Foggia Prostate Cancer Risk Calculator 2.0: A Novel Risk Calculator including MRI and Bladder Outlet Obstruction Parameters to Reduce Unnecessary Biopsies.

Risk calculator (RC) combining PSA with other clinical information can help to better select patients at risk of prostate cancer (PCa) for prostate biopsy. The present study aimed to develop a new Pca RC, including MRI and bladder outlet obstruction parameters (BOOP). The ability of these parameters in predicting PCa and clinically significant PCa (csPCa: ISUP GG ≥ 2) was assessed by binary logistic regression. A total of 728 patients were included from two institutions. Of these, 395 (54.3%) had negative biopsies and 161 (22.11%) and 172 (23.6%) had a diagnosis of ISUP GG1 PCa and csPCa. The two RC ultimately included age, PSA, DRE, prostate volume (pVol), post-voided residual urinary volume (PVR), and PIRADS score. Regarding BOOP, higher prostate volumes (csPCa: OR 0.98, CI 0.97,0.99) and PVR ≥ 50 mL (csPCa: OR 0.27, CI 0.15, 0.47) were protective factors for the diagnosis of any PCa and csPCa. AUCs after internal validation were 0.78 (0.75, 0.82) and 0.82 (0.79, 0.86), respectively. Finally, decision curves analysis demonstrated higher benefit compared to the first-generation calculator and MRI alone. These novel RC based on MRI and BOOP may help to better select patient for prostate biopsy after prostate MRI.

Arrhythmic myocarditis in an adolescent male: A unique presentation of multi-organ inflammatory syndrome (MIS-C).

Although children with Covid-19 generally present with mild symptoms or are often asymptomatic, there is increasing recognition of a delayed multi-organ inflammatory syndrome (MIS-C) following SARS-CoV-2 infection. We report the case of MIS-C associated arrhythmic myocarditis which recovered after anti-inflammatory therapy and immunoglobulin infusion.

MRI morphological evaluation of humeral head bone profile inside region of the biceps pulley reflection.

OBJECTIVE: Evaluating humeral head bone profile inside biceps reflection pulley area in order to identify possible anatomical variants and any causes predisposing to tendon's instability of the long head of the biceps. MATERIALS AND METHODS: This retrospective study analyzed 326 patients, 183 males and 143 females (age 15-88 years; average 51.5 years), who underwent MRI examination between 2013 and 2019. Biceps pulley reflection area morphology of 192 right shoulders and 134 left shoulders was assessed analyzing 309 MRI and 17 MR arthrography (MRA) shoulder exams. We investigated age and gender and the frequency of morphological variants among the patient groups. RESULTS: Four possible morphological variants were identified: 95 with convex shape; 127 with flat shape; 77 with spiculated shape; and 12 with mixed morphology. Fifteen humeral bone profiles were not classifiable. CONCLUSIONS: MRI was effective in defining humeral head anatomic variants inside the biceps pulley reflection area. The most frequent variants were flat or convex types.

Radiologist-rheumatologist multidisciplinary approach in the management of axial spondyloarthritis: a Delphi consensus statement.

OBJECTIVES: The aim of this study was to develop a Delphi consensus statement between rheumatologists and radiologists for the diagnosis and monitoring of axial spondyloarthritis (axial-SpA). METHODS: Following an extensive literature search to identify unmet needs and potential goals for a multidisciplinary approach, a scientific board comprising 28 Italian hospital-based rheumatologists (n=19) and radiologists (n=9) identified 8 "starting points", resulting in the development of 23 consensus statements covering issues from current practice guidelines to specific MRI protocols for the assessment of axial-SpA. Each participant anonymously expressed a level of agreement for each statement using a 5-point Likert scale (1="strongly disagree"; 5="strongly agree") via an online Delphi method.Total cumulative agreement (TCA) was defined as the sum of the percentage of response to items 4 ("agree") and 5 ("absolutely agree"). Consensus was defined as ≥80% total cumulative agreement for each statement. RESULTS: After the first round of voting (28 participants), positive consensus was reached for 28/31 (90.3%) statements. Statements without consensus (n=3) were discussed in a face-to-face plenary session prior to the second vote (28 participants). After the second round voting, positive consensus was attained for all 31 statements, with mean final TCA of 95.5% (range 82.1-100%). CONCLUSIONS: This Delphi consensus statement provides an aid to rheumatologists and radiologists for the diagnosis and monitoring of axial-SpA.

Maxillary Sinus Mass as First Presentation of Silent Metastatic Renal Cell Carcinoma.

Renal cell carcinoma accounts for more than 3% of all malignant diseases. Metastatic disease to the head and neck ranges from 15% to 30%. The 5-year survival rate after nephrectomy is 60% to 75%, but with multiorgan metastases the 5-year survival rate is significantly lower, 0% to 7%. The authors present the case of a patient with a progressive, painless right facial swelling over the maxillary area of 3-month's duration associated with a considerable decrease of right visual acuity. Cranial computed tomography scan and magnetic resonance imaging showed a maxillary sinus mass extending to the orbital cavity and 2 choroidal and retinal thickenings. The mass biopsy was performed by Caldwell-Luc procedure and pathology report suggested metastatic renal cell carcinoma. Following histological findings, a total body computed tomography scan showed a heterogeneous mass at the middle-lower portion of the right kidney measuring approximately 8 × 12 × 4 cm with associated ipsilateral renal vein thrombosis. The patient was referred to the Oncology Department for further treatment. Unfortunately, 3 months after the mass biopsy, the patient died due to complications of multiorgan failure. Although metastases of renal cell carcinoma to the head and neck are very rare, it should be first suspected when investigating a metastatic tumor in this region.

Percutaneous Computed Tomography-Guided Lung Biopsies using a Virtual Navigation Guidance: Our Experience.

OBJECTIVE: To evaluate the effectiveness of a virtual CT-guided navigation system (Sirio-MASMEC Biomed) in performing lung biopsies, with greater attention to lesions smaller than 1 cm, compared to the traditional procedure. METHODS: This study was approved by the Ethics Committee of our Institute. Two hundred patients were prospectively selected. Of these, 100 were subjected to percutaneous procedure with the use of Sirio and 100 to traditional CT-guided percutaneous procedure. The two methods were compared in terms of absorbed dose, procedure time, complications, and number of non-diagnostic specimens (diagnostic success). RESULTS: Sirio has shown a significant reduction in the absorbed dose and procedure times (p < 0.05), with a lower incidence of complications compared to the traditional procedure. Sirio has also allowed to carry out biopsies of lesions' diameter ≤10 mm, obtaining fewer non diagnostic specimens thus resulting more effective in terms of diagnostic success. CONCLUSIONS: The use of Sirio in sampling biopsy showed a statistically significant reduction in terms of performed scans and procedural time with lower incidence of post-procedural complications compared to the traditional percutaneous procedure, especially for lesions ≤10 mm. The best diagnostic result, the reduction of the dose absorbed and procedural complications makes the procedures more reliable, safety and less invasive. In addition, the reduction of execution time will increase the number of daily interventional procedures improving clinical management.

Can Diffusion-Weighted Imaging and Related Apparent Diffusion Coefficient be a Prognostic Value in Women With Breast Cancer?

PURPOSE: To analyze diffusion-weighted imaging (DWI) and the related apparent diffusion coefficient (ADC) in women with breast cancer, correlating these values with the presence at 3 years of distant metastases, and to demonstrate that DWI-Magnetic Resonance Imaging (MRI) and related ADC values may represent a prognostic value in the study of women with breast cancer. MATERIALS AND METHODS: Sixty women (aged 45-73 years) affected with breast cancer with a follow-up in 3 years were enrolled. On DWI, we obtained the ADC values, and these were correlated with the clinical condition of patients at 3 years. Moreover, tumour size, lymph node status, and molecular markers, including estrogens receptor, progesterone receptor, Ki-67 index, and human growth factor receptor 2 protein, were correlated with ADC values. This study was approved by the Scientific Committee of our institution. RESULTS: We considered patients with metastasis at 3 years (12 patients - 20%) and without metastasis (48 patients - 80%). The mean ADC value in patients with no metastases at 3 years was 1.06 ± 0.38, while for patients with metastases it was 0.74 ± 0.34 (p = .011). The receiver-operator curve analysis identified a value of 0.75 (<0.75 with risk to develop metastasis) as the best predictive cutoff for ADC values, with the highest sensitivity (81.25%) and higher specificity (66.67%). After regression analysis, ADC value, positivity to estrogen-progestin receptors, and presence of lymph nodes were the only prognostic factors found to be statistically significant. CONCLUSIONS: DWI-MRI and related ADC values may represent a prognostic value in women with breast cancer.

Magnetic Resonance Imaging in the Pre-Surgical Staging of Breast Cancer: Our Experience.

PURPOSE: To investigate the clinical impact of magnetic resonance imaging (MRI) in the detection of multifocal-multicentric breast cancers, already identified by mammography and ultrasound, and analyzed histologically, to evaluate its role in preoperative staging. MATERIALS AND METHODS: From January 2012 to February 2014, 188 patients, aged 28 to 74 years, newly diagnosed with breast cancer on conventional imaging (mammography and ultrasound) were enrolled. They underwent preoperative contrast-enhanced 3T MRI. Patients underwent surgery according to international guidelines. Results of all diagnostic procedures were compared. RESULTS: Among the 188 patients, 163 (87%) had a unilateral and unifocal tumor at both conventional imaging; MRI diagnosed 22/22 (100%) of multifocal and multicentric tumors, the combination of mammography and ultrasound diagnosed 12/22 (54%), and mammography alone diagnosed 8/22 (36%) multifocal and multicentric tumors. MRI prompted a change in surgical strategy in 10/188 (5%) patients. This change comprised mastectomy instead of conservative surgery (n = 7) and more extensive conservative surgery (n = 3). CONCLUSIONS: MRI was confirmed to show higher sensitivity than conventional imaging in detecting multifocal and multicentric breast cancers.

Prolonged QT and myocardium recovery after primary PCI: a cMRI study.

BACKGROUND: The presence of viable stunned myocardium recovering after primary angioplasty is not easy to identify in the early phase of acute myocardial infarction (AMI) by noninvasive bed-side methods. We therefore aimed to assess whether a simple electrocardiogram parameter may be of help in identifying the presence of stunned viable myocardium recovering after reperfusion with primary angioplasty. MATERIALS AND METHODS: A total of 14 consecutive patients with ST-elevation AMI (STEMI) were enrolled in the study and underwent QT duration assessment after admission: the difference between QT corrected (QTc) in the ischaemic areas and QTc values in nonischaemic areas was therefore calculated and compared with the presence and the extension of viable stunned myocardium, assessed by comparing akinetic/dyskinetic areas at admission echocardiography with akinetic/dyskinetic areas and extension of scar at 6-month cardiac magnetic resonance imaging (cMRI). RESULTS: In subjects with viable recovering myocardium, 75% had a QTc max > 440 ms (vs. 17%, P = 0·03); higher differential QTc values and smaller scar areas were found (33 ms vs. -17 ms, 14% vs. 27%, P = 0·03, 0·06 respectively). Differential QTc values > 0 were able to identify the presence of viable myocardium with an odds ratio of 35 (P < 0·05, sensitivity 88%, specificity 83%, positive predictive power 88%, negative predictive power of 83%). Differential QTc values were related to the extension of viable recovering myocardium (P < 0·001). CONCLUSION: Viable myocardium recovering after primary angioplasty in STEMI may be predicted by the presence of increased QTc values in ischaemic areas in comparison with nonischaemic areas.

Spleen assessment after laparoscopic transperitoneal left adrenalectomy: preliminary results.

BACKGROUND: Several laparoscopic approaches to the adrenal gland have been described. We prefer the lateral transabdominal approach. The aim of this study is to evaluate prospectively the presence of any anatomical and dynamic changes in the spleen after laparoscopic transperitoneal left adrenalectomy (LTLA), which can cause an increased risk of early and late complications. METHODS: We have evaluated 21 patients before and 6 months after surgery in order to verify the possible presence of a wandering spleen. A clinical and instrumental follow-up [ultrasound (US), magnetic resonance (MR)] were performed. During US protocol, in supine, right lateral, and orthostatic position, the longitudinal and anteroposterior diameter of the spleen and the resistive index within 3 cm of the origin of the splenic artery in three different measurements averaged were measured. MR protocol evaluated, in supine and right lateral position, the splenic volume and its distances from the diaphragm dome and the lateral margin of the costal arch. RESULTS: p Values calculated for each parameter were not statistically significant. Our results confirm the absence of any anatomical and dynamic changes in the spleen after LTLA. CONCLUSIONS: The most common complications after laparoscopic adrenalectomy are well known and widely described. Our experience does not exclude the occurrence of a wandering spleen, but allows us to state that a rightful mobilization of the pancreaticosplenic block can avoid this event, and in agreement with other authors, the presence of a wandering spleen remains an isolated complication.

Magnetic resonance enterography changes after antibody to tumor necrosis factor (anti-TNF) alpha therapy in Crohn's disease: correlation with SES-CD and clinical-biological markers.

BACKGROUND: In recent years, the use of MRI in patients with Crohn's disease (CD) has increased. However, few data are available on how MRI parameters of active disease change during treatment with anti-TNF and whether these changes correspond to symptoms, serum biomarkers, or endoscopic appearance. The aim of this study was to determine the changes over time in MRI parameters during treatment with anti-TNF in patients with CD, and to verify the correlation between MRI score, endoscopic appearance and clinical-biological markers. METHODS: We performed a prospective single centre study of 27 patients with active CD (18 males and 9 females; median age of 27,4 ys; age range, 19-49). All patients underwent ileocolonoscopy and MRI at baseline and 26 weeks after anti-TNF therapy. Endoscopic severity was graded according to the Simple Endoscopic Score for Crohn's Disease (SES-CD) and Magnetic Resonance Index of Activity (MaRIA) was calculated. Patients underwent clinical evaluation (CDAI) and the C-reactive protein (CRP) level was measured. The associations between variables were assessed with Pearson's bivariate correlation analysis. RESULTS: A total of 135 intestinal segments were studied. The median patient age was 27,4 years, 67 % were male and the mean disease duration was 6,1 years. For induction of remission, 18 patients were treated with infliximab and 9 with adalimumab. The mean SES-CD and MaRIA scores significantly changed at week 26 (SES-CD: 14,7 ± 8,9 at baseline vs. 4,4 ± 4,6 at 26 weeks - p < 0.001; MaRIA: 41,1 ± 14,8 at baseline vs. 32,8 ± 11,7 at 26 weeks - p < 0.001). Also the CDAI and serum levels of CRP decreased significantly following treatment (p < 0.001). The overall MaRIA correlated with endoscopic score and with clinical activity (CDAI) both at baseline and at week 26 (p < 0.05). The correlation between overall MaRIA and CRP was significant only at week 26 (p < 0.001). CONCLUSIONS: The MaRIA has a good correlation with SES-CD, a high accuracy for prediction of endoscopic mucosal healing and is a reliable indicator to monitor the use of TNF antagonists in patients with CD.

Diffusion weighted imaging and apparent diffusion coefficient in 3 tesla magnetic resonance imaging of breast lesions.

OBJECTIVE: To evaluate the utility of diffusion-weighted-imaging (DWI) and apparent-diffusion-coefficient (ADC) in a 3T magnetic-resonance-imaging (MRI) study of breast cancer. In particular, the study aims to classify ADC-values according to histology either for benign or malignant lesions. METHODS: 110 Breast MRI with MRI-DWI sequences and quantitative evaluation of the ADC were retrospectively reviewed. Results obtained with MRI-DWI and with biopsy were analyzed and ADC values were compared to histological results. RESULTS: MRI showed a 95.5% sensitivity and a 83.7% specificity. The mean ADC values of benign and malignant lesions were 2.06 ± 0.19 and 1.03 ± 0.07 mm(2)/s, respectively (p < .05). CONCLUSIONS: DWI and ADC-values could help distinguishing malignant and benign breast masses.

Italian Registry of Cardiac Computed Tomography.

PURPOSE: Cardiac CT (CCT) is an imaging modality that is becoming a standard in clinical cardiology. We evaluated indications, safety, and impact on patient management of routine CCT in a multicenter national registry. MATERIALS AND METHODS: During a period of 6 months, 47 centers in Italy enrolled 3,455 patients. RESULTS: CCT was performed mainly with 64-slice CT scanners (73.02 %). Contrast agents were administrated in 3,185 patients (92.5 %). Mean DLP changes with type of scanner and was lower in >64 row detector scanner. The most frequent indication for CCT was suspected CAD (44.8 %), followed by calcium scoring (9.6 %), post-angioplasty/stenting (8.3 %), post-CABGs (7.5 %), study of cardiac anatomy (4.22 %) and assessment in patients with known CAD (4.1 %) and acute chest pain (1.99 %). Most of the CCTs were performed in outpatient settings (2,549; 74 %) and a minority in inpatient settings (719, 20.8 %). Adverse clinical events (mild-moderate) occurred in 26 examinations (0.75 %). None of them was severe. In 45.3 % of the cases CCT findings impacted patient management. CONCLUSION: CCT is performed with different workloads in participating centers. It is a safe procedure and its results have a strong impact on patient management.

Magnetic resonance imaging of penile paraffinoma: case report.

BACKGROUND: Penile paraffinoma is a well-known delayed complication of paraffin oil injection into the penis for penile girth augmentation but its MRI features have not been previously described. CASE PRESENTATION: A 35-year-old Ukraine man presented with erectile dysfunction, voiding difficulty and an irregular, hard and painful penile mass that had progressively grown over the last year. He reported having received, seven years before, several penile injections of paraffin oil for penile girth augmentation. On physical examination, the mass was tender, poorly delimited, and involved the whole penile shaft and the cranial part of the scrotum. Preoperative MRI, performed to determine the extent of tissue to be removed and the possibilities of penile reconstruction, showed a newly-formed homogeneous tissue, compressing but not infiltrating Buck's fascia, iso-hypointense relative to muscle on T1-weighted sequences, and with a low signal intensity at T2-weighted sequences. On T1-weighted fat suppressed sequences, it did not enhance with contrast administration. MRI data were confirmed by surgical findings, as the newly-formed scar tissue did not infiltrate Buck's fascia. Pathology confirmed the diagnosis of penile paraffinoma. CONCLUSION: MRI seems to provide an adequate imaging of the histological events occurring after injection of paraffin oil in the subcutaneous tissues. Penile paraffinoma remains a clinical diagnosis, but MRI features may be helpful in planning an adequate surgical strategy and, in selected cases, establishing the differential diagnosis with other penile diseases, including cancer.

Radiofrequency thermal ablation of renal tumors.

Percutaneous radiofrequency ablation (PRFA) of renal malignancies is currently a therapeutic option for patients who are not able to undergo surgery. Some authors consider PRFA as the therapeutic standard in the treatment of renal neoplasms in non-operable patients due to comorbid conditions and in patients with mild-moderate renal failure, to preserve residual renal functionality. The use of PRFA has become more and more widespread due to a rise in the incidental detection of renal cell carcinomas with the ever-increasing use of Imaging for the study of abdominal diseases. Clinical studies indicate that RF ablation is an effective therapy with a low level of risk of complications, which provides good results in selected patients over short and medium term periods of time, however up to now few long-term studies have been carried out which can confirm the effectiveness of PRFA.

Left Ventricle Noncompaction Phenotype: Cause or Consequence?

Left ventricular noncompaction (LVNC) is commonly described as a congenital cardiomyopathy characterized by prominent myocardial trabeculae and deep intertrabecular recesses extending in the left ventricular chamber. Clinical presentation can differ considerably from asymptomatic individuals to those presenting with heart failure and other serious complications. Diagnosis is usually made by two-dimensional transthoracic echocardiography or cardiac magnetic resonance. Moreover, even if strain parameters are significantly reduced in patients with LVNC, they are not routinely investigated. Here, we report the case of a previously symptomless patient admitted to the hospital for pulmonary edema. Two-dimensional transthoracic echocardiography showed severe valvular heart disease and left ventricle pronounced trabeculation and remodeling, although speckle tracking echocardiography (STE) demonstrated only mild strain reduction. We, therefore, explore the possibility that STE may be useful to differentiate LVNC cardiomyopathy from LVNC phenotype due to severe remodeling.

Vertebral and Femoral Bone Mineral Density (BMD) Assessment with Dual-Energy CT versus DXA Scan in Postmenopausal Females.

This study aimed to demonstrate the potential role of dual-energy CT in assessing bone mineral density (BMD) using hydroxyapatite-fat material pairing in postmenopausal women. A retrospective study was conducted on 51 postmenopausal female patients who underwent DXA and DECT examinations for other clinical reasons. DECT images were acquired with spectral imaging using a 256-slice system. These images were processed and visualized using a HAP-fat material pair. Statistical analysis was performed using the Bland-Altman method to assess the agreement between DXA and DECT HAP-fat measurements. Mean BMD, vertebral, and femoral T-scores were obtained. For vertebral analysis, the Bland-Altman plot showed an inverse correlation (R2: -0.042; RMSE: 0.690) between T-scores and DECT HAP-fat values for measurements from L1 to L4, while a good linear correlation (R2: 0.341; RMSE: 0.589) was found for measurements at the femoral neck. In conclusion, we demonstrate the enhanced importance of BMD calculation through DECT, finding a statistically significant correlation only at the femoral neck where BMD results do not seem to be influenced by the overlap of the measurements on cortical and trabecular bone. This outcome could be beneficial in the future by reducing radiation exposure for patients already undergoing follow-up for chronic conditions.

Comparison between Gleason score and apparent diffusion coefficient obtained from diffusion-weighted imaging of prostate cancer patients.

OBJECTIVES: To correlate the apparent diffusion coefficient (ADC) of prostate cancer patients with pathological Gleason scores (GS). METHODS: 40 patients with GS 2 + 3, 3 + 3, 3 + 4, or 4 + 4 were selected. The magnetic resonance imaging (MRI) study was performed adding axial diffusion-weighted imaging (DWI) sequences to the standard MRI protocol. ADC values obtained were correlated with the GS data. RESULTS: Statistically significant differences of ADC (p < .05) were found among GS groups with a trend of decreasing ADC values with increasing GS. CONCLUSIONS: The ADC values may help clinicians to delineate prostate carcinoma, recognizing its high- or low-grade compartments.

[Role of urographic 64 CT examination for the evaluation of kidney inflammation diseases]. / Ruolo della TC 64-strati con metodica urografica nelle patologie flogistiche renali.

In the study of inflammatory kidney diseases, the use of integrated imaging is considered the best diagnostic approach. However, given the high cost of radiological examinations, the radiologist is responsible for the choice of the best method to solve the question asked by the clinician. In this paper are presented the main imaging methods for the study of pyelonephritis and, based on our experience, it is emphasized the role of multidetector Computed Tomography urographic technique in the identification, characterization and subsequent follow-up of inflammatory kidney diseases.
