Sex differences in acute health service contact after release from prison in Australia: a data linkage study.

OBJECTIVES: Women released from prison typically experience worse health outcomes than their male counterparts. We examined sex differences in the patterns, characteristics, and predictors of acute health service contact (AHSC) (i.e. ambulance and/or emergency department use) after release from prison. STUDY DESIGN: Data linkage study. METHODS: Baseline survey data from 1307 adults (21% women) within six weeks of expected release from prisons in Queensland, Australia (2008-2010) were linked prospectively with state-wide ambulance and emergency department, correctional, mental health, and death records. Crude and adjusted incidence rates and incidence rate ratios of AHSC were calculated overall and by sex. An Andersen-Gill model was fit to examine whether sex predicted AHSC. The interaction effect between sex and each model covariate was tested. RESULTS: The crude incidence rates of AHSC after release from prison were 1.4 (95% confidence interval [CI]: 1.3-1.5) and 1·1 (95%CI: 1.1-1.2) per person-year for women and men, respectively. The relationship between perceived physical health-related functioning at the baseline and AHSC was modified by sex (P = 0·039). The relationship between perceived health-related functioning and AHSC also differed among women. Compared to women who perceived their physical health as fair or good at the baseline, women who perceived their physical health as poor were at greater risk of AHSC (hazard ratio = 2.4, 95%CI: 1.4-3·9, P = 0.001) after release from prison. CONCLUSIONS: Among people released from prison, women's and men's AHSC differs depending on how they perceive their own physical health. The specific needs of women and men must be considered in transitional support policy and planning to improve their health outcomes.

Diagnostic value of diffusion-weighted imaging (DWI) for the assessment of the small bowel in patients with inflammatory bowel disease.

AIM: To evaluate diffusion-weighted imaging (DWI) compared to standard magnetic resonance imaging (sMRI) in the assessment of inflammatory lesions of the small bowel. MATERIALS AND METHODS: Two readers retrospectively analysed MRI images of the small bowel including DWI followed by capsule endoscopy (CE) and ileocolonoscopy (ICS) in 30 consecutive patients with a suspected or established diagnosis of inflammatory bowel disease. Small bowel CE and the combination of CE + ICS were used as the standards of reference. Inflammatory lesions of the small bowel detected at endoscopy were compared with the findings of (1) sMRI alone (MRI without DWI), (2) DWI alone, and (3) sMRI in combination with DWI (sMRI + DWI). The sensitivity, specificity, and accuracy were calculated for all three readouts. The results of the three readouts were compared with each other. RESULTS: Using CE + ICS as the standard of reference, the mean sensitivity and specificity for the detection of inflammatory lesions of the small bowel at sMRI were 55.2% and 99.5%, at DWI 60% and 99%, and at sMRI + DWI 70% and 99%. Interobserver agreement between the two readers was very good (k=0.87-0.95). Two lesions in different patients were only detected at DWI. CONCLUSION: DWI of the small bowel not only allowed for the detection of inflammatory lesions with high accuracy, but also enabled the identification of additional lesions that were not found using sMRI alone.

Intellectual disability and patient activation after release from prison: a prospective cohort study.

BACKGROUND: Intellectual disability and patient activation may be important drivers of inequities in health service access and health outcomes for people with intellectual disability transitioning from prison to the community. We assessed the association between intellectual disability and patient activation after prison release and examined whether this association varied, depending on whether intellectual disability was identified prior to prison release. METHODS: Overall, 936 prisoners were screened for intellectual disability by using the Hayes Ability Screening Index and completed the Patient Activation Measure (PAM) within 6 weeks of prison release and again at 1, 3 and 6 months post-release. We estimated the association between intellectual disability status and PAM scores by using a multilevel linear model, adjusting for sociodemographic, behavioural, health and criminogenic factors. We used propensity score matching to estimate the impact of being identified with intellectual disability prior to release from prison on the change in mean PAM score after prison release. RESULTS: Compared with those who screened negative for intellectual disability, ex-prisoners who screened positive, both with and without prior identification of intellectual disability, had significantly decreased mean PAM scores [(B = -4.3; 95% CI: -6.3, -2.4) and (B = -4.5; 95% CI: -6.8, -2.3), respectively] over 6 months of follow-up. Among those who reported being identified with intellectual disability prior to release from prison, a significant increase in PAM score at the 6-month follow-up interview (B = 5.89; 95% CI: 2.35, 9.42; P = 0.001) was attributable to being identified with intellectual disability prior to release. CONCLUSIONS: Ex-prisoners screening positive for possible intellectual disability have decreased patient activation for at least 6 months after release from prison. However, individuals whose possible intellectual disability is unidentified appear to be particularly vulnerable. Incarceration is a pivotal opportunity for the identification of intellectual disability and for initiating transitional linkages to health and intellectual disability-specific community services for this marginalised population.

Trajectories of psychological distress after prison release: implications for mental health service need in ex-prisoners.

BACKGROUND: Understanding individual-level changes in mental health status after prison release is crucial to providing targeted and effective mental health care to ex-prisoners. We aimed to describe trajectories of psychological distress following prison discharge and compare these trajectories with mental health service use in the community. METHOD: The Kessler Psychological Distress Scale (K10) was administered to 1216 sentenced adult prisoners in Queensland, Australia, before prison release and approximately 1, 3 and 6 months after release. We used group-based trajectory modeling to identify K10 trajectories after release. Contact with community mental health services in the year following release was assessed via data linkage. RESULTS: We identified five trajectory groups, representing consistently low (51.1% of the cohort), consistently moderate (29.8%), high increasing (11.6%), high declining (5.5%) and consistently very high (1.9%) psychological distress. Mood disorder, anxiety disorder, history of self-harm and risky drug use were risk factors for the high increasing, very high and high declining trajectory groups. Women were over-represented in the high increasing and high declining groups, but men were at higher risk of very high psychological distress. Within the high increasing and very high groups, 25% of participants accessed community mental health services in the first year post-release, for a median of 4.4 contact hours. CONCLUSIONS: For the majority of prisoners with high to very high psychological distress, distress persists after release. However, contact with mental health services in the community appears low. Further research is required to understand barriers to mental health service access among ex-prisoners.

Comparison of social circumstances, substance use and substance-related harm in soon-to-be-released prisoners with and without intellectual disability.

BACKGROUND: The transition out of prison is likely to be a challenging time for prisoners with intellectual disability (ID). However, little evidence exists to inform interventions for people with ID making this transition. In this study we aimed to describe social circumstances, patterns of substance use and substance-related harm in soon-to-be-released prisoners with ID. We compare this group with those without ID, to better understand how the health-related needs of this group compare with the 'mainstream' prison population. METHODS: Data came from face-to-face, confidential interviews with 1325 adult prisoners in seven adult prisons in Queensland, Australia. Prisoners with ID were identified using the Hayes Ability Screening Index (HASI). We used cross-sectional data to examine (i) demographics and criminographics; (ii) social circumstances; and (iii) substance use and substance use related harm. We compared characteristics of those with and without ID using univariable logistic regression. RESULTS: Prisoners with ID (n = 115) were more likely than their peers without ID to be male, to identify as Indigenous Australian, and to report low educational attainment (<10 years) and pre-incarceration unemployment. Those with ID reported a high prevalence of poly-drug use (28.0%), unsafe tattooing (51.1%), unsafe sex (91.0%) and HCV infection (55.6%), although differences with their peers were non-significant. CONCLUSIONS: The health and social needs of prisoners with ID transitioning into the community are a significant concern for researchers, policy makers and practitioners. Our findings highlight the need for proactive, appropriate and targeted service responses from disability, health and justice sectors.

Inter-rater reliability of the Hayes Ability Screening Index in a sample of Australian prisoners.

BACKGROUND: Reliable ascertainment of intellectual disability (ID) is important to identify those with special needs, in order for those needs to be met in the criminal justice system. Although the Hayes Ability Screening Index (HASI) is valid and widely used for the identification of possible ID, the risk of inter-rater bias between researchers when scoring the HASI has not yet been established. The current paper estimates the inter-rater reliability of the HASI in a sample of Indigenous and non-Indigenous prisoners in Western Australia. METHODS: We estimated intra-class correlation coefficients (ICC) for the consistency of agreement among three blinded raters using a two-way random-effects model assessing the inter-rater agreement of the HASI. Kappa was also estimated for the dichotomous HASI screening threshold outcome between the raters. RESULTS: The HASI exhibited very good within-subject consistency of agreement for Section B (ICC = 0.95; 95%CI:0.94-0.96), Section C (ICC = 0.97; 95%CI: 0.96-0.98) and Section D (ICC = 0.90; 95%CI: 0.87-0.92) subscales and for the total scaled score (ICC = 0.97; 95%CI: 0.96-0.98). The inter-rater reliability of the dichotomous adult ID screening threshold (<85) was also very good (Kappa = 0.95). CONCLUSIONS: The current study provides new evidence that the HASI has a low risk of bias from between-rater scoring and can be reliably scored by both non-clinicians and clinicians with little training, when administered in prison settings. Pre-scoring training should focus on the more subjective 'clock-drawing' section, in order to maximise inter-rater reliability.

Addition of diffusion-weighted imaging can improve diagnostic confidence in bowel MRI.

AIM: To evaluate whether the addition of diffusion-weighted imaging (DWI) in bowel abdominal magnetic resonance imaging (MRI) can improve diagnostic confidence. MATERIALS AND METHODS: One hundred and eleven consecutive patients with suspected or known inflammatory bowel disease (n = 59), tumour disease (n = 31), unspecific abdominal pain (n = 16), and suspected graft-versus-host disease (n = 5) underwent bowel MRI using a 1.5 T MRI machine. In addition to T2-weighted (T2W) and contrast-enhanced T1-weighted (CE-T1W) data, axial and coronal DWI sequences were collected (b = 50, 500, 1000). Diagnostic confidence for lesion detection with and without DWI was evaluated using a four-point Likert scale [1 = certainly no lesion(s), 2 = probably no lesion(s), 3 = probably lesion(s), 4 = certainly lesion(s)]. RESULTS: In 11 of 111 patients (10%), the diagnostic confidence was improved by DWI. In seven patients, readers changed their diagnosis from "probable" to "certain presence of lesions". In another four patients, lesions were diagnosed based on DWI, which were not delineated on CE-T1W and T2W imaging. CONCLUSION: DWI of the bowel can provide additional information to the reader and, therefore, improve diagnostic confidence. Hence, additional DWI should be integrated into a standard bowel MRI protocol.

First-pass contrast-enhanced renal MRA at 7 Tesla: initial results.

OBJECTIVE: The aim of this study was to assess the feasibility of first-pass contrast-enhanced renal MR angiography (MRA) at 7 T. METHODS: In vivo first-pass contrast-enhanced high-field examinations were obtained in eight healthy subjects on a 7-T whole-body MRI. A custom-built body transmit/receive radiofrequency (RF) coil and RF system suitable for RF shimming were used for image acquisition. For dynamic imaging, gadobutrol was injected intravenously and coronal unenhanced, arterial and venous data sets using a T1-weighted spoiled gradient-echo sequence were obtained. Qualitative image analysis and assessment of artefact impairment were performed by two senior radiologists using a five-point scale (5 = excellent, 1 = non-diagnostic). SNR and CNR of the perirenal abdominal aorta and both main renal arteries were assessed. RESULTS: Qualitative image evaluation revealed overall high-quality delineation of all assessed segments of the unenhanced arterial vasculature (meanunenhanced 4.13). Nevertheless, the application of contrast agent revealed an improvement in vessel delineation of all the vessel segments assessed, confirmed by qualitative (meanunenhanced 4.13 to meancontrast-enhanced 4.85) and quantitative analysis (SNR meanunenhanced 64.3 to meancontrast-enhanced 98.4). CONCLUSION: This study demonstrates the feasibility and current constraints of ultra-high-field contrast-enhanced renal MRA relative to unenhanced MRA.

Physical health outcomes in prisoners with intellectual disability: a cross-sectional study.

BACKGROUND: People with intellectual disability (ID) in the general population and people in prison experience unrecognised medical conditions and inadequate disease prevention. Among prisoners, those with an ID may be particularly disadvantaged. The aim of this study was to identify demographic, health and health-related characteristics of adult prisoners who screened positive for ID. METHODS: Cross-sectional data were collected via face-to-face administration of a structured questionnaire in seven prisons in Queensland, Australia, between 2008 and 2010. Participants were adult prisoners within 6 weeks of release from custody. We identified ID using a pragmatic screening tool. Prisoners who scored <85 on the Hayes Ability Screening Index and either (a) reported having attended a special school or (b) reported having been diagnosed with an ID were considered to have screened positive for ID. We compared the characteristics of participants who screened positive and negative for ID using univariable and multivariable logistic regression. RESULTS: Screening positive for ID was associated with younger age, identifying as Indigenous and lower educational achievement. Prisoners who screened positive for ID were more likely to have been diagnosed with medical conditions such as heart disease (odds ratio; 95% confidence interval = 2.1; 1.0-4.2) and hearing problems (2.2; 1.3-3.7), after adjustment for age, sex, education level and Indigenous status. Screen-positive prisoners were less likely to have received preventive care interventions such as testing for hepatitis A infection (0.4; 0.2-0.6), and immunisation for tuberculosis (0.4; 0.2-0.8). Prisoners with possible ID were more likely to be obese (1.7; 1.1-2.7). CONCLUSIONS: Adult prisoners who screen positive for ID have worse health outcomes than their non-disabled peers. An improved understanding of physical health characteristics prior to release can direct treatment and support pathways out of the criminal justice system and inform transitional planning of health services for this profoundly disadvantaged group.

New look at renal vasculature: 7 tesla nonenhanced T1-weighted FLASH imaging.

PURPOSE: To investigate the feasibility of 7 Tesla (T) nonenhanced high field MR imaging of the renal vasculature and to evaluate the diagnostic potential of various nonenhanced T1-weighted (T1w) sequences. MATERIALS AND METHODS: Twelve healthy volunteers were examined on a 7T whole-body MR system (Magnetom 7T, Siemens Healthcare Sector) using a custom-built eight-channel radiofrequency (RF) transmit/receive body coil. Subsequent to RF shimming, the following sequences were acquired (i) fat-saturated two-dimensional (2D) FLASH, (ii) fat-saturated 3D FLASH, and a (iii) fat-saturated 2D time-of-flight MR angiography (TOF MRA). SNR and CNR were measured in the aorta and both renal arteries. Qualitative analysis was performed with regard to vessel delineation (5-point scale: 5 = excellent to 1 = nondiagnostic) and presence of artifacts (5-point scale: 5 = no artifact present to 1 = strong impairment). RESULTS: The inherently high signal intensity of the renal arterial vasculature in T1w imaging enabled moderate to excellent vessel delineation in all sequences. Qualitative (mean, 4.7) and quantitative analysis (SNR(mean) : 53.9; CNR(mean) : 28.0) demonstrated the superiority of TOF MRA, whereas 2D FLASH imaging provided poorest vessel delineation and was most strongly impaired by artifacts (overall impairment 3.7). The 3D FLASH MRI demonstrated its potential for fast high quality imaging of the nonenhanced arterial vasculature, providing homogeneous hyperintense vessel signal. CONCLUSION: Nonenhanced T1w imaging in general and, TOF MRA in particular, appear to be promising techniques for good quality nonenhanced renal artery assessment at 7 Tesla.

Impact of dual diagnosis on healthcare and criminal justice costs after release from Queensland prisons: a prospective cohort study.

BACKGROUND: People released from prison have poorer health than the general public, with a particularly high prevalence of mental illness and harmful substance use. High-frequency use of hospital-based services is costly, and greater investment in transitional support and primary care services to improve the health of people leaving prison may therefore be cost-effective. METHODS: A prospective cohort study of 1303 men and women released from prisons in Queensland, Australia, between 2008 and 2010, using linked data was performed. We calculated healthcare costs and the cost of re-incarceration. We compared healthcare costs to the general public, and assessed the impact of past mental illness, substance use disorder, and dual diagnosis on both healthcare and criminal justice costs. RESULTS: Healthcare costs among the cohort were 2.1-fold higher than expected based on costs among the public. Dual diagnosis was associated with 3.5-fold higher healthcare costs (95% CI 2.6-4.6) and 2.8-fold higher re-incarceration costs (95% CI 1.6-5.0), compared with no past diagnosis of either mental illness or substance use disorder. CONCLUSIONS: People released from prison incur high healthcare costs, primarily due to high rates of engagement with emergency health services and hospital admissions. Comorbid mental illness and substance use disorders are associated with high health and criminal justice costs among people recently released from prison.

Modifiable risk factors for external cause mortality after release from prison: a nested case-control study.

AIM: People released from prison are at higher risk of mortality from potentially preventable causes than their peers in the general population. Because most studies of this phenomenon are reliant on registry data, there is little health and behavioural information available on those at risk, hampering the development of targeted, evidence-based preventive responses. Our aim was to identify modifiable risk and protective factors for external cause and cause-specific mortality after release from prison. METHODS: We undertook a nested case-control study using data from a larger retrospective cohort study of mortality after release from prison in Queensland, Australia between 1994 and 2007. Cases were 286 individuals who had died from external causes (drug overdose, suicide, transport accidents, or violence) matched with 286 controls on sex, Indigenous status, and release date. We extracted data from detention, case-management, and prison medical records. RESULTS: Factors associated with increased risk of external cause mortality included use of heroin and other opioids in the community [odds ratio (OR) = 2.20, 95% CI 1.41-3.43, p < 0.001], a prescription for antidepressants during the current prison sentence (OR = 1.94, 95% CI 1.02-3.67, p = 0.042), a history of problematic alcohol use in the community (OR = 1.54, 95% CI 1.05-2.26, p = 0.028), and having ever served two or more custodial sentences (OR = 1.51, 95% CI 1.01-2.25, p = 0.045). Being married (OR = 0.45, 95% CI 0.29-0.70, p < 0.001) was protective. Fewer predictors were associated with cause-specific mortality. CONCLUSIONS: We identified several behavioural, psychosocial, and clinical markers associated with mortality from preventable causes in people released from prison. Emerging evidence points to interventions that could be targeted at those at increased risk of external cause mortality. These include treatment and harm reduction programmes (for substance use), improving transitional support programmes and continuity of care (for mental health), diversion and drug reform (for repeat incarceration) and nurturing stable relationships during incarceration. The period of imprisonment and shortly after release provides a unique opportunity to improve the long-term health of ex-prisoners and overcome the disadvantage associated with imprisonment.

[MR colography: technique, indications, and findings]. / MR-Kolonographie: Technik, Indikationen und Befunde.

Magnetic resonance imaging (MRI) has evolved as a powerful tool that has been applied more and more in recent years for the assessment of gastrointestinal structures, owing to its unsurpassed soft tissue contrast, lack of radiation exposure, and implementation of fast scanning techniques. As a virtual endoscopic technique, MR colography (MRC) makes it possible to image inflammatory processes and tumor disease of the large intestine with a high degree of accuracy. In this article we describe current techniques and applications of MRC and give an overview of clinical studies comparing MRC with other diagnostic procedures.

Deep Brain Nuclei T1 Shortening after Gadobenate Dimeglumine in Children: Influence of Radiation and Chemotherapy.

BACKGROUND AND PURPOSE: Intrinsic T1-hyperintense signal has recently been reported in the deep gray nuclei on brain MR imaging after multiple doses of gadolinium-based contrast agents. Most reports have included adult patients and excluded those undergoing radiation or chemotherapy. We investigated whether T1 shortening is also observed in children and tried to determine whether radiochemotherapy is a risk factor for this phenomenon. MATERIALS AND METHODS: In this single-center retrospective study, we reviewed clinical charts and images of all patients 18 years of age or younger with ≥4 gadobenate dimeglumine-enhanced MRIs for 6 years. Seventy-six children (mean age, 9.3 years; 60 unconfounded by treatment, 16 with radiochemotherapy) met the selection criteria (>4 MR imaging examinations; mean, 8). T1 signal intensity ratios for the dentate to pons and globus pallidus to thalamus were calculated and correlated with number of injections, time interval, and therapy. RESULTS: Among the 60 children without radiochemotherapy, only 2 had elevated T1 signal intensity ratios (n = 20 and 16 injections). Twelve of the 16 children with radiochemotherapy showed elevated signal intensity ratios. Statistical analysis demonstrated a significant signal intensity ratio change for the number of injections (P < .001) and amount of gadolinium (P = .008), but not for the interscan time interval (P = .35). There was a significant difference in the average signal intensity ratio change between those with and without radiochemotherapy (P < .001). Chart review revealed no new neurologic deficits in any patients, related to their underlying conditions and prior surgeries. CONCLUSIONS: Compared with published adult series, children show a similar pattern of T1 hyperintense signal changes of the dentate and globus pallidus after multiple gadobenate dimeglumine injections. The T1 signal changes in children may have a later onset but are accelerated by radiochemotherapy.

Attitudes towards seclusion and restraint in mental health settings: findings from a large, community-based survey of consumers, carers and mental health professionals.

AIMS: There are growing calls to reduce, and where possible eliminate, the use of seclusion and restraint in mental health settings, but the attitudes and beliefs of consumers, carers and mental health professionals towards these practices are not well understood. The aim of this study was to compare the attitudes of mental health service consumers, carers and mental health professionals towards seclusion and restraint in mental health settings. In particular, it aimed to explore beliefs regarding whether elimination of seclusion and restraint was desirable and possible. METHODS: In 2014, an online survey was developed and widely advertised in Australia via the National Mental Health Commission and through mental health networks. The survey adopted a mixed-methods design, including both quantitative and qualitative questions concerning participants' demographic details, the use of seclusion and restraint in practice and their views on strategies for reducing and eliminating these practices. RESULTS: In total 1150 survey responses were analysed. A large majority of participants believed that seclusion and restraint practices were likely to cause harm, breach human rights, compromise trust and potentially cause or trigger past trauma. Consumers were more likely than professionals to view these practices as harmful. The vast majority of participants believed that it was both desirable and feasible to eliminate mechanical restraint. Many participants, particularly professionals, believed that seclusion and some forms of restraint were likely to produce some benefits, including increasing consumer safety, increasing the safety of staff and others and setting behavioural boundaries. CONCLUSIONS: There was strong agreement across participant groups that the use of seclusion and restraint is harmful, breaches human rights and compromises the therapeutic relationship and trust between mental health service providers and those who experience these restrictive practices. However, some benefits were also identified, particularly by professionals. Participants had mixed views regarding the feasibility and desirability of eliminating these practices.

Blue rubber bleb nevi (BRBN) are rare vascular malformations of the integument and mucous membranes. Little is known about coherence between these nevi and malignant diseases. We report on a young man with progressive BRBN syndrome representing a thitherto unknown malignant melanoma.

Resumption of injecting drug use following release from prison in Australia.

INTRODUCTION: Ex-prisoners with a history of injecting drug use (IDU) experience disproportionate drug-related harm. Rapid resumption of substance use following prison release is common and evidenced in high rates of overdose mortality. However, few studies have documented the rate of IDU resumption following prison release or identified risk factors for relapse. METHODS: Structured interviews were conducted with 533 adults with a history of IDU in Queensland, Australia prior to release from prison and approximately 1, 3 and 6 months post-release. Incidence of self-reported IDU resumption was calculated overall and for each follow-up interval. Risk factors associated with time to resumption of IDU were estimated using discrete-time survival analysis. RESULTS: IDU resumption was reported by 41% of participants during a median of 98days of follow-up (IQR=94-121), an overall crude incidence of 1.06 per person-year. The highest rate was observed in the first month (23%; crude incidence 2.24 per person-year). In adjusted discrete-time survival analyses, being unemployed at the previous interview (AHR=1.59; 95%CI:1.10-2.30), shorter incarceration (≤90days vs. >365days; AHR=2.20; 95%CI:1.33-3.65), and IDU during the index incarceration (AHR=2.80; 95%CI:1.92-4.09) were significantly associated with time to IDU resumption; parole was protective (AHR=0.66; 95%CI:0.47-0.92). CONCLUSIONS: Evidence-based efforts to prevent IDU in prison and IDU resumption after release are important for both prisoner and public health. Enhancing opportunities for employment and capitalising on the short-term benefits of parole for ex-prisoners may delay resumption of IDU after release from prison. These strategies should complement rather than replace harm reduction efforts for this high-risk population.

A Review of Scientific Topics and Literature in Abdominal Radiology in Germany--Part 2: Abdominal Parenchymal Organs.

UNLABELLED: The working group for abdominal and gastrointestinal diagnosis is a group of the German Radiological Society (DRG) focusing clinically and scientifically on the diagnosis and treatment of the gastrointestinal tract as well as the parenchymal abdominal organs. In this article we give an up-to-date literature review of scientific radiological topics especially covered by German radiologists. The working group experts cover the most recent relevant studies concerning liver-specific contrast media with an emphasis on a new classification system for liver adenomas. Additionally studies regarding selective internal radiotherapy (SIRT) are reviewed. For the pancreas the most important tumors are described followed by an introduction to the most recently introduced functional imaging techniques. The manuscript concludes with some remarks on recent studies and concerning chronic pancreatitis as well as autoimmune pancreatitis. KEY POINTS: • Different subtypes of liver adenomas with different therapeutic consequences can be differentiated by MRI • Most recently published studies focus on liver imaging with extracellular liver specific contrast media as well as diffusion weighted imaging. They consider this new method having a high diagnostic potential. • For pancreatic neoplasm diagnosis diffusion--as well as perfusion--imaging is considered as a highly promising method.

A Review of Scientific Topics and Literature in Abdominal Radiology in Germany - Part 1: Gastrointestinal Tract.

UNLABELLED: The working group for abdominal and gastrointestinal diagnosis is a group of the German Radiological Society (DRG) focusing clinically and scientifically on the diagnosis and treatment of the gastrointestinal tract with all parenchymatous abdominal organs. In addition to the clinical and scientific further development of abdominal radiology, the education of radiologists within this core discipline of radiology is one of the major aims. In this article we give an up-to-date literature review of scientific radiological topics especially covered by German radiologists. This manuscript focuses on the most recent literature on the diagnosis of the stomach, small bowel, colon and rectum. The review with a focus on the most recent studies published by German radiologists concludes with a synopsis of mesenterial bleeding and ischemia followed by a critical appraisal of the current literature on conventional abdominal radiography. KEY POINTS: Based on recent literature and guidelines there is a change of paradigms regarding the diagnosis of esophagus and gastric cancer towards CT, which is considered equally to endosonography. For small bowel imaging in Crohn's disease ultrasound as well as MRI with a new focus on DWI are the most important imaging modalities scientifically. For colonic diagnosis virtual colonoscopy has replaced the conventional radiological methods. For staging of rectal carcinoma as well as for therapeutic stratification a high resolution MRI of the pelvis is of paramount interest. Multislice CT is considered the most important modality to assess mesenteric ischemia or bleeding.

Magnetic resonance imaging of the bowel: today and tomorrow.

Magnetic resonance imaging of the small bowel has been feasible for more than 15 years. This review is meant to give an overview of typical techniques, sequences and indications. Furthermore, newly evaluated promising techniques are presented, which have an impact on the advance of MR imaging of the small and large bowel.
