RESUMO
PURPOSE: Bladder neck stricture (BNS) is a bothersome disease which may affect patients after trauma or prostatic surgery. It is frustrating due to the low durable success rate of currently available surgical techniques. The aim of the study is to explore the efficacy of a novel technique. MATERIALS & METHODS: The surgical protocol was developed by two high case-volume surgeons. The technique consists of Holmium laser incisions at 3-6-9-12 o'clock. Subsequently, triamcinolone acetonide 40 mg is injected. Two months later, the BNS is endoscopically checked in operatory room and re-procedure take place, if necessary (max 3 times). Failure was defined as the need of definitive urinary diversion. Subjective satisfaction was measured through PGI-I Questionnaire. RESULTS: A total of 45 patients were enrolled. Median age was 63 (IQR 59-69) years and BNS developed by different causes. Naïve BNS procedure patients were 12 (26.7%), others 33 (73.3%) underwent median 2 (IQR 1-4) previous urethrotomies, including 16 other surgeries. Suprapubic bladder catheter was present in 34 patients (75.6%). No complications were registered. Re-procedure at control was necessary in 24 patients (53.3%) for a median of 1 (IQR 1-3) procedures. At median follow-up of 18 months, failures were 4 (8.9%) and urinary incontinence was reported in 2 patients (4.5%) who required incontinence surgery. Median PGI-I was 2. CONCLUSIONS: Our technique of BNS treatment allows good outcomes and high rate of subjective improvement amongst patients. Moreover, naïve patients seem to have better results. However, longer follow-up and higher sample size are mandatory to further assess these data.

BACKGROUND: The ectopic pelvic kidney, a common renal anomaly, is often smaller and malformed, with a shorter and sometimes tortuous ureter (1). Muscle-invasive bladder cancer (MIBC), constituting 15-25% of bladder cancer cases (2), mandates radical cystectomy with a 50% 5-year survival rate (2). Despite the growing use of robot-assisted radical cystectomy (RARC) (3, 4), there is limited data on its application in ectopic kidneys. Only one RARC case has been reported (5), in contrast to numerous open radical cystectomies (1, 6) involving an ectopic kidney. PATIENT AND METHODS: After being diagnosed with T2 high-grade urothelial carcinoma, the 66-year-old patient, previously treated with multiple transurethral resections and adjuvant BCG therapy, received neoadjuvant chemotherapy. Preoperative staging CT revealed a 2.6 x 2.2 cm bladder neoformation and an ectopic right pelvic kidney. RESULTS: Using the da Vinci Surgical System, radical cystectomy with ileal conduit (sec Wallace II) and lymphadenectomy were performed. During the demolition phase, the shorter right ureter was dissected with care to avoid damage to the renal pedicle. The reconstructive phase included intracorporeal urinary diversion (ICUD) and uretero-ileal anastomosis, facilitated by the favorable position of the kidney. The 8-hour console surgery resulted in minimal blood loss. Discharged on day 16 due to COVID-19, the patient exhibited positive outcomes. A 2-month CT follow-up revealed no cancer recurrence, metastasis, hydronephrosis, and complete regression of the lymphocele. Imaging follow-up continues without postoperative adjuvant chemotherapy. CONCLUSION: Robotic surgery with intracorporeal urinary diversion holds potential for right-sided pelvic kidney cases, but additional studies are necessary for validation.

OBJECTIVES: To develop a structured reporting (SR) template for whole-body CT examinations of polytrauma patients, based on the consensus of a panel of emergency radiology experts from the Italian Society of Medical and Interventional Radiology. METHODS: A multi-round Delphi method was used to quantify inter-panelist agreement for all SR sections. Internal consistency for each section and quality analysis in terms of average inter-item correlation were evaluated by means of the Cronbach's alpha (Cα) correlation coefficient. RESULTS: The final SR form included 118 items (6 in the "Patient Clinical Data" section, 4 in the "Clinical Evaluation" section, 9 in the "Imaging Protocol" section, and 99 in the "Report" section). The experts' overall mean score and sum of scores were 4.77 (range 1-5) and 257.56 (range 206-270) in the first Delphi round, and 4.96 (range 4-5) and 208.44 (range 200-210) in the second round, respectively. In the second Delphi round, the experts' overall mean score was higher than in the first round, and standard deviation was lower (3.11 in the second round vs 19.71 in the first round), reflecting a higher expert agreement in the second round. Moreover, Cα was higher in the second round than in the first round (0.97 vs 0.87). CONCLUSIONS: Our SR template for whole-body CT examinations of polytrauma patients is based on a strong agreement among panel experts in emergency radiology and could improve communication between radiologists and the trauma team.

Electric scooters have become very popular over the past five years. However, their growing popularity and their easy availability are strongly related to an increasing number of injuries. These accidents are more common among young people and typically occurred during the night. The great majority of patients admitted to an emergency department receive at least one imaging examination, which commonly is an X-ray or a computed tomography scan. In electric scooter trauma, the head, maxillofacial region, and upper and lower extremities are more vulnerable than the thoracoabdominal region and spine. Among fractures, the nasal bone, radius and tibia are most involved. Intracranial injuries are rare but are an important cause of disability and possible death. Although most patients with electric scooter trauma are discharged home, these accidents often require outpatient follow-up and sometimes hospitalization. Due to the growing number of this type of trauma, it is important for an emergency radiologist to know the pattern of injuries.

BACKGROUND: Low-intensity shockwave therapy (Li-SWT) is a promising option for the treatment of erectile dysfunction (ED). Many devices with different characteristics in terms of generators, shockwaves, set-up parameters and procedure protocols are commercially available. In this report, we present our experience with the main shockwave technologies currently in use in clinical practice for ED treatment. METHODS: A retrospective national, multi-institutional study was performed to compare the effects of different shockwave technologies in ED patients. All of the subjects underwent 8 consecutive weekly physical treatments with SWT under either a focused or non-focused regimen: 3,000 shocks per session at 0.09 mJ/mm2 and 10,000 shocks per session at 15 Hz and 90 mJ, respectively. Efficacy was evaluated by comparing pre- and post-treatment Sexual Health Inventory in Men (SHIM) scores, International Index of Erectile Function (IIEF-5) and Erection Hardness Score (EHS). Possible relationships between type of shockwave generator, source, morphology and type of ED were investigated. RESULTS: A total of 94 men were included in the analysis. There were no significant differences in the baseline clinical characteristics or demographics. The mean (SD) increase in the scores from questionnaires evaluated at 8 weeks was clinically and statistically significant, with overall improvements of +5.49, +5.47 and +1.18 (p<0.0001) in the IIEF-5, SHIM, and EHS scores, respectively. The increases in these scores were evaluated by a multiple regression analysis, in relation to the shockwave generator, type of ED, shockwave source and morphology, but none of the factors examined predicted improvement. No side effects were reported with any device. CONCLUSIONS: SWT is a clinically effective and safe treatment for ED that is independent of the generator type, source, shockwave morphology emitted, type of ED and perhaps treatment protocol.

This article discusses three important pieces of work that the Competition and Markets Authority has completed over the last year. The first two are market studies: The Mobile Ecosystems Market Study was launched over concerns that Apple and Google have too much control over operating systems (iOS and Android), app stores (App Store and Play Store), and web browsers (Safari and Chrome) that together form their 'ecosystems'; the Electric Vehicles Charging Market Study took actions and provided recommendations in a nascent but critically important market. The final piece of work is "State of Competition": a research project that assesses the evolution of competition in the UK over the past two decades.
RESUMO
OBJECTIVES: To investigate whether diet restriction affects quality of colon cleansing and patient tolerance during reduced bowel preparation for CT colonography (CTC). METHODS: Asymptomatic and symptomatic patients were enrolled in this pragmatic, single-centre, randomised trial. All patients were randomly assigned (1:1 ratio, blocks of ten) to receive a reduced bowel preparation and faecal tagging with (Diet-Restriction-Group [DR]) or without (No-Diet-Restriction-Group [NDR]) dietary restriction. Five readers performed a blinded subjective image analysis, by means of 4-point Likert-scales from 0 (highest score) to 3 (worst score). Endpoints were the quality of large bowel cleansing and tolerance to the assigned bowel preparation regimen. The trial is registered at ClinicalTrial.gov (URomLSDBAL1). RESULTS: Ninety-five patients were randomly allocated to treatments (48 in NDR-group, 47 in DR-group). Both groups resulted in optimal colon cleansing. The mean residual stool (0.22, 95%CI 0.00-0.44) and fluid burden (0.39, 95%CI 0.25-0.53) scores for patients in DR-group were similar to those in patients in NDR-group (0.25, 95%CI 0.03-0.47 [p = 0.82] and 0.49, 95%CI 0.30-0.67 [p = 0.38], respectively). Tolerance was significantly better in NDR-group. CONCLUSION: A reduced bowel preparation in association with faecal tagging and without any dietary restriction demonstrated optimal colon cleansing effectiveness for CTC, providing better patient compliance compared with dietary restriction. KEY POINTS: ⢠Dietary restriction in reduced bowel preparation regimen can be avoided. ⢠The quality of colon cleansing is not affected by dietary restriction. ⢠The quality of faecal tagging is not affected by dietary restriction. ⢠Avoidance of dietary restriction improves patients' tolerance for CTC.

OBJECTIVES: To assess the opinion on structured reporting (SR) and its usage by radiologist members of the Italian Society of Medical Radiology (SIRM) via an online survey. METHODS: All members received an email invitation to join the survey as an initiative by the SIRM Imaging Informatics Chapter. The survey included 10 questions about demographic information, definition of radiological SR, its usage in everyday practice, perceived advantages and disadvantages over conventional reporting and overall opinion about SR. RESULTS: 1159 SIRM members participated in the survey. 40.3 % of respondents gave a correct definition of radiological SR, but as many as 56 % of them never used it at work. Compared with conventional reporting, the most appreciated advantages of SR were higher reproducibility (70.5 %), better interaction with referring clinicians (58.3 %) and the option to link metadata (36.7 %). Risk of excessive simplification (59.8 %), template rigidity (56.1 %) and poor user compliance (42.1 %) were the most significant disadvantages. Overall, most respondents (87.0 %) were in favour of the adoption of radiological SR. CONCLUSIONS: Most radiologists were interested in radiological SR and in favour of its adoption. However, concerns about semantic, technical and professional issues limited its diffusion in real working life, encouraging efforts towards improved SR standardisation and engineering. KEY POINTS: ⢠Despite radiologists' awareness, radiological SR is little used in working practice. ⢠Perceived SR advantages are reproducibility, better clinico-radiological interaction and link to metadata. ⢠Perceived SR disadvantages are excessive simplification, template rigidity and poor user compliance. ⢠Improved standardisation and engineering may be helpful to boost SR diffusion.

Small bowel jejunoileal diverticulosis is an uncommon and usually asymptomatic condition. Complications may occur such as acute diverticulitis including infection or perforation, bleeding, small bowel obstruction and volvulus. Herein we report a case of a 76 years-old woman with acute left side abdominal pain and tenderness. A clinical suspected diagnosis of colonic diverticulitis was formulated. She underwent Ultrasound that revealed a collapsed small bowel loop with a large sac-like out-pouching lesion with mixed content (fluid and pockets of air) associated to hyperechogenicity of perilesional fat. Because of the atypical US findings, the patient underwent abdominopelvic CT that confirmed that the large sac-like out-pouching was a jejunal inflamed diverticulum. The patient underwent emergency surgery. Radiologist should be aware of imaging findings of jejunoileal diverticulitis in order to achieve a prompt diagnosis.
RESUMO
APOE ε4 allele is the major genetic risk factor for Alzheimer's Disease (AD). Furthermore, APOE methylation pattern has been described to be associated with the disease and to follow a bimodal pattern, with a hypermethylated CpG island and a hypomethylated promoter region. However, little is known about the methylation levels in the APOE 5'UTR region. Here, the methylation of two regions (R1 and R2) within APOE 5'UTR was investigated in both peripheral blood mononuclear cells (PBMCs) and hippocampus (HIC) samples to identify differentially methylated CpG sites and to associate clinical, genetic features and cerebrospinal fluid (CSF) biomarkers levels. DNA was extracted from PBMCs of 20 AD and 20 healthy controls (HC) and from 6 AD and 3 HC HIC samples. The methylation analysis was carried out by means of pyrosequencing. In AD PBMCs we found that R1 region displayed a higher methylation level, while the opposite trend was observed in R2. The presence of ε4 allele highlighted a marked increase in R1 methylation level and a decrease in R2. In AD PBMCs and HIC, age progression resulted to be associated with an increase in the methylation level of R1. Lastly, the methylation of a CpG site in R2 was found to be related to CSF biomarkers. Despite the lack of a statistical significance, the outcome from this exploratory analysis highlighted the presence of a difference in methylation in APOE 5'UTR in PBMCs of AD patients which seemed to be associated also with APOE genotype, age and CSF biomarkers level.
RESUMO
BACKGROUND: Recurrent and complex stone disease may be considered a challenging disease. In 2018, the Calculus group of the SIU (Italian Society of Urology) set itself the goal of establishing the minimum requirements for a center that could continuously manage urolithiasis pathology, named a Stone Center. In this study we present the results of a pilot survey carried out in 2019 with the aim of drawing a map of the situation of Italian urological centers dealing with urinary stones. METHODS: A total of 260 national urology departments dealing with urolithiasis surgery were contacted for this study. A survey was issued to each of the centers to determine the number of patients treated for urinary stones and the amount of procedures performed per year: 1) extracorporeal shock wave lithotripsy ESWL; 2) ureterorenoscopy URS; 3) retrograde intrarenal surgery RIRS; 4) percutaneous nephrolithotomy PCNL. RESULTS: Out of 260 centers contacted, 188 fulfilled the survey. Outcomes were quite variable, with approximately 37% of the centers lacking a lithotripter, and 46% of those that did have it performing fewer than 100 treatments per year. In terms of endoscopic procedures, more than 80% of the centers contacted performed URS or RIRS; however, when it came to percutaneous lithotripsy, these numbers dropped significantly; 33% of the centers contacted did not perform PCNL, and of those who did, 18% had less than 5 years of experience as a center. CONCLUSIONS: Our survey shows a very heterogeneous national picture about urolithiasis treatments. Our goal is to create national paradigms to be able to define stone centers where the patient suffering from complex urinary stones can find a network of professionals with an adequate armamentarium suitable for the management of their pathology.

The central nervous system (CNS) is surrounded by three membranes called meninges. Specialised fibroblasts, originating from the mesoderm and neural crest, primarily populate the meninges and serve as a binding agent. Our goal was to compare fibroblasts from meninges and skin obtained from the same human-aged donors, exploring their molecular and cellular characteristics related to CNS functions. We isolated meningeal fibroblasts (MFs) from brain donors and skin fibroblasts (SFs) from the same subjects. A functional analysis was performed measuring cell appearance, metabolic activity, and cellular orientation. We examined fibronectin, serpin H1, ß-III-tubulin, and nestin through qPCR and immunofluorescence. A whole transcriptome analysis was also performed to characterise the gene expression of MFs and SFs. MFs appeared more rapidly in the post-tissue processing, while SFs showed an elevated cellular metabolism and a well-defined cellular orientation. The four markers were mostly similar between the MFs and SFs, except for nestin, more expressed in MFs. Transcriptome analysis reveals significant differences, particularly in cyclic adenosine monophosphate (cAMP) metabolism and response to forskolin, both of which are upregulated in MFs. This study highlights MFs' unique characteristics, including the timing of appearance, metabolic activity, and gene expression patterns, particularly in cAMP metabolism and response to forskolin. These findings contribute to a deeper understanding of non-neuronal cells' involvement in CNS activities and potentially open avenues for therapeutic exploration.

BACKGROUND: Stone nomogram by Micali et al., able topredict treatment failure of shock-wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) in the management of single 1-2 cm renal stones, was developed on 2605 patients and showed a high predictive accuracy, with an area under ROC curve of 0.793 at internal validation. The aim of the present study is to externally validate the model to assess whether it displayed a satisfactory predictive performance if applied to different populations. METHODS: External validation was retrospectively performed on 3025 patients who underwent an active stone treatment from December 2010 to June 2021 in 26 centers from four countries (Italy, USA, Spain, Argentina). Collected variables included: age, gender, previous renal surgery, preoperative urine culture, hydronephrosis, stone side, site, density, skin-to-stone distance. Treatment failure was the defined outcome (residual fragments >4 mm at three months CT-scan). RESULTS: Model discrimination in external validation datasets showed an area under ROC curve of 0.66 (95% 0.59-0.68) with adequate calibration. The retrospective fashion of the study and the lack of generalizability of the tool towards populations from Asia, Africa or Oceania represent limitations of the current analysis. CONCLUSIONS: According to the current findings, Micali's nomogram can be used for treatment prediction after SWL, RIRS and PNL; however, a lower discrimination performance than the one at internal validation should be acknowledged, reflecting geographical, temporal and domain limitation of external validation studies. Further prospective evaluation is required to refine and improve the nomogram findings and to validate its clinical value.

PURPOSE: To assess the effect of computer-aided detection (CAD) as a second reader on the sensitivity and specificity of computed tomographic (CT) colonography in detecting 6-9-mm colorectal cancer (CRC) lesions. MATERIALS AND METHODS: Individuals with clinical indications for colonoscopy--either for symptoms or as part of participating in a surveillance program or CRC screening--were prospectively enrolled at one of 10 academic centers between July 2007 and May 2009. Institutional review board approval was obtained at each clinical site, and all participants provided written informed consent. All participants underwent CT colonography and colonoscopy on the same day. Experienced readers interpreted the CT colonography images unassisted and then reviewed all colorectal lesion-like structures pinpointed by the CAD algorithm. Segmental unblinding of CT colonoscopy findings at colonoscopy was utilized. The sensitivity and specificity of unassisted and CAD-assisted reading in identifying individuals with 6-9-mm lesions were calculated and compared by means of pairwise analysis. RESULTS: A total of 618 participants (mean age, 57.9 years; 54.5% male) were included in the final analysis. Of these participants, 464 (75.1%) had no lesions 6 mm or larger, and 52 (8.4%) had 6-9-mm lesions. The sensitivity of CT colonography with unassisted reading and that with CAD-assisted reading in identifying individuals with 6-9-mm lesions was 65.4% (95% confidence interval [CI]: 50.9%, 78.0%) and 76.9% (95% CI: 63.2%, 87.5%; P = .016), respectively. No significant change in specificity was observed: The specificity of CT colonography with unassisted and that with CAD-assisted reading was 91.8% (95% CI: 88.9%, 94.1%) and 90.9% (95% CI: 88.0%, 93.4%; P = .063), respectively. Evaluation of CAD candidates required an additional 1.6 minutes (25th-75th percentile: 1.0 minute to 3.4 minutes). CONCLUSION: The addition of CAD to reading performed by experienced readers resulted in a significant benefit in the detection of 6-9-mm polyps at CT colonography in this cohort.

(1) Background: While females start their gynecological examinations during puberty, only few men decide to be visited by urologists in their youth. Given the participation in the EcoFoodFertility research project, our department had the opportunity to screen young males that were supposedly healthy. (2) Results: from January 2019 to July 2020, we evaluated 157 patients with sperm, blood analysis, and uroandrological examinations. The inclusion criteria were age 18-40 and absence of previous urological disease (urology-naïve). The primary endpoint of the study was to record uroandrological diseases that are occasionally discovered during examination in asymptomatic young men. The average age was 26.9 years (range 18-40); average testicular volume was 15.7 mL (range 12-22 mL); and 45.2% reported abnormal semen analysis: 62 cases of teratozoospermia, 27 asthenozoospermia, 18 oligozoospermia, and 2 azoospermia were discovered respectively; 4/157 patients were diagnosed with hypogonadism; 2 cases with suspicious testicular mass resulted in testicular cancer; and 31 suspected varicoceles and 8 patients with mild sexual dysfunctions were managed. (3) Conclusions: an uroandrological evaluation of young asymptomatic males allowed for the prompt diagnosis of different urological conditions, including cancerous ones, in our series. Despite being debatable, combining urological counselling with physical examination, semen analysis, and a laboratory profile could be useful and cost-effective in order to ameliorate male health.
RESUMO
BACKGROUND: The prevalence of kidney stones tends to increase worldwide due to dietary and climate changes. Disease management involves a high consumption of healthcare system resources which can be reduced with primary prevention measures and prophylaxis of recurrences. In this field, collaboration between general practitioners (GPs) and hospitals is crucial. METHODS: a panel composed of general practitioners and academic and hospital clinicians expert in the treatment of urinary stones met with the aim of identifying the activities that require the participation of the GP in the management process of the kidney stone patient. RESULTS: Collaboration between GP and hospital was found crucial in the treatment of renal colic and its infectious complications, expulsive treatment of ureteral stones, chemolysis of uric acid stones, long-term follow-up after active treatment of urinary stones, prevention of recurrence and primary prevention in the general population. CONCLUSIONS: The role of the GP is crucial in the management and prevention of urinary stones. Community hospitals which are normally led by GPs in liaison with consultants and other health professional can have a role in assisting multidisciplinary working as extended primary care.

BACKGROUND: Green Light laser enucleation of the prostate (GreenLEP) is an endoscopic treatment to treat bladder outlet obstruction in men with large prostate (>100 cc). Herein, we describe our GreenLEP series and describe its safety and efficacy. METHODS: Between February 2014 and April 2019, 120 patients from a single center underwent en-bloc GreenLEP with early apical release. All procedures were performed with the AMS XPS laser generator (set: 120 W for vaporization and 20 W for coagulation). Morcellation was carried out with the Wolf Piranha morcellator. Data concerning the pre-, intra- and postoperative outcomes were prospectively collected. The follow-up data at 6, 12 months and at the last control were collected. RESULTS: The median age was 66.0 (IQR: 61.0-71.0) years; 37.5% of the patients were under antiplatelet/anticoagulant therapy, 15.0% had indwelling catheter history. The median prostate volume and the baseline PSA value were 98.5 mL (IQR 83.0-130.0) and 4.2 ng/mL (IQR: 3.2-6.8), respectively. The median operative and lasing time were 65.0 (IQR: 51.0-83.5) and 6.0 (IQR: 6.0-10.0) minutes, respectively. In the postoperative period 1 patient was transfused. The median follow-up was 18.0 (IQR: 12.0-39.5) months. All patients had significant improvement in terms of improvement of uroflowmetry (median from 9 mL/sec [IQR 7.8, 11.0] to 20.0 [IQR 18.0, 22.0], P<0.001) and symptoms control (IPSS median score from 26.0 mL/sec [IQR 22.0, 28.0] to 7.0 [IQR 6.0, 8.0], P<0.001]) over time. After 12 months 1 patient complained of stress incontinence (1 pad/day) and 1 of "de novo" wet urgency. CONCLUSIONS: En-bloc GreenLEP with early apical release is a safe and effective procedure even for large volume prostates. It allows us to limit the use of laser energy and shorten the operating times with stable and satisfactory long-term outcomes.

Here, we aim to describe COVID-19 pathology across different tissues to clarify the disease's pathophysiology. Lungs, kidneys, hearts, and brains from nine COVID-19 autopsies were compared by using antibodies against SARS-CoV-2, macrophages-microglia, T-lymphocytes, B-lymphocytes, and activated platelets. Alzheimer's Disease pathology was also assessed. PCR techniques were used to verify the presence of viral RNA. COVID-19 cases had a short clinical course (0-32 days) and their mean age was 77.4 y/o. Hypoxic changes and inflammatory infiltrates were present across all tissues. The lymphocytic component in the lungs and kidneys was predominant over that of other tissues (p < 0.001), with a significantly greater presence of T-lymphocytes in the lungs (p = 0.020), which showed the greatest presence of viral antigens. The heart showed scant SARS-CoV-2 traces in the endothelium-endocardium, foci of activated macrophages, and rare lymphocytes. The brain showed scarce SARS-CoV-2 traces, prominent microglial activation, and rare lymphocytes. The pons exhibited the highest microglial activation (p = 0.017). Microthrombosis was significantly higher in COVID-19 lungs (p = 0.023) compared with controls. The most characteristic pathological features of COVID-19 were an abundance of T-lymphocytes and microthrombosis in the lung and relevant microglial hyperactivation in the brainstem. This study suggests that the long-term sequelae of COVID-19 derive from persistent inflammation, rather than persistent viral replication.

The advent of multidetector computed tomography (MDCT) revolutionized abdominal imaging. In particular, the definitive assessment of CT injection protocols, for the evaluation of the liver parenchyma, is still a critical issue for radiologists. Over the last years, this feature encouraged several authors to address their efforts to find the most accurate delay between the contrast medium injection and the effective scan-start, for the identification and characterization of liver lesions. Technological developments of the present century such as number of slices, submillimetric collimation, and the use of multiple dynamic post-contrast phases per single examination, may all contribute to increase the radiation exposure of single patients. The aim of this review is to propose liver imaging protocols, taking into consideration different clinical needs such as patients with chronic liver disease, healthy patients with focal liver lesion, and oncological patients to minimize radiation exposure. Finally, two recent innovations in MDCT which illustrate the potential application of multi-energy computed tomography (MECT) and perfusion computed tomography (CTp) when evaluating liver parenchyma will be discussed in a short closing paragraph.
