RESUMEN
Isolated gallbladder rupture are rare injuries. We present a case of gallbladder traumatic rupture in a 47-year-old patient involved in a motor vehicle collision, that presented abdominal pain with maximal intensity in the right upper quadrant.CT is the imaging technique of choice to diagnosis this entity, however the final diagnosis of gallbladder rupture is confirmed with laparoscopy. Cholecystectomy is the definitive treatment.

Purpose: The aim of this multicentric study is to illustrate how the COVID-19 pandemic lockdown affected the workload and outcomes of radiological examinations in emergency radiology. Material and methods: The exams performed in the radiology departments of 4 Italian hospitals during 3 weeks of the Italian lockdown were retrospectively reviewed and compared to the exams conducted during the same period in 2019. Only exams from the emergency department (ED) were included. Two radiologists from each hospital defined the cases as positive or negative findings, based on independent blind readings of the imaging studies. In the case of differences in the evaluation, consensus was reached amongst them via discussion. Continuous measurements are presented as median and interquartile range, while categorical measurements are presented as frequency and percentage; p-values were calculated using the t-test, Mann-Whitney test, and the c2 test. Results: There were 745 patients (53% male; 62 years [44-78]) who underwent radiological examinations in 2020 vs. 2623 (52% male; 56 years [35-76]) in 2019 (p < 0.001). Furthermore, the total number of ED exams dropped from 3206 (2019) to 939 (2020), with a relative increase of CT examinations from 23% to 33% (p < 0.001). The percentage of patients with a positive finding was significantly higher in 2020 (355, 48%) compared to 2019 (684, 26%) (p < 0.001). Conclusions: Our findings show that despite the reduction of emergency radiological examinations, there was a rela-tive increase in the number of positive cases. These significant findings are crucial to ensure better organization of radiology departments and improve patient management during similar health emergencies in the future.
RESUMEN
OBJECTIVES: Guidelines recommend chest radiography (CR) in the workup of suspected acute aortic syndromes (AASs) if the pretest clinical probability is low. However, the diagnostic impact of CR integration for the rule-in and rule-out of AASs is unknown. METHODS: We performed a secondary analysis of the ADvISED multicenter study. Emergency department outpatients were eligible if an AAS was clinically suspected. Clinical probability was defined with the aortic dissection detection risk score (ADD-RS). CR was evaluated blindly by a radiologist, who judged on mediastinum enlargement (ME) and other signs. RESULTS: In 2014 through 2016, a total of 1,129 patients were enrolled and 1,030 were analyzed, including 48 (4.7%) with AASs. ADD-RS/ME and ADD-RS/any CR sign (aCRs) integration were more accurate than ADD-RS alone (area under the curve = 0.8 and 0.78 vs. 0.66, p < 0.001). The sensitivity and specificity of the integrated strategies were 66.7% (95% confidence interval [CI] = 51.5% to 79.9%) and 82.5% (95% CI = 79.9% to 84.8%) for ADD-RS/ME and 68.8% (95% CI = 53.6% to 80.9%) and 76.5% (95% CI = 73.7% to 79.1%) for ADD-RS/aCRs, respectively. The sensitivity and specificity of CR per se were 54.2% (95% CI = 39.2% to 68.6%) and 92.4% (95% CI = 90.5% to 93.9%) for ME and 60.4% (95% CI = 45.3% to 74.2%) and 85.2% (95% CI = 82.9% to 87.4%) for aCRs. The agreement (κ) between attending physicians and radiologists for ME was 0.44 (95% CI = 0.35 to 0.54). ADD-RS/ME rule-in (ADD-RS ≤ 1 and ME-present, or ADD-RS > 1) applied to 204 versus 130 patients with ADD-RS > 1, including 14 with AAS and 60 false-positives (FP). ADD-RS/aCRs rule-in (ADD-RS ≤ 1 and aCRs-present, or ADD-RS > 1) applied to 264 patients, including 15 with AAS and 119 FP. ADD-RS/ME rule-out (ADD-RS ≤ 1 and ME-absent) applied to 826 (80.2%) patients, including 16 with AAS (33.3% of cases). ADD-RS/aCRs rule-out (ADD-RS ≤ 1 and aCRs-absent) applied to 766 patients (74.4%), including 15 with AAS (31.3% of cases). CONCLUSIONS: CR integration with clinical probability assessment showed modest rule-in efficiency and insufficient sensitivity for conclusive rule-out.

OBJECTIVES: To compare the CACS and CAD severity assessed by MDCT in neuropathic type-2 diabetic patients with and without Charcot-neuroarthropathy (CN). METHODS: Thirty-four CN asymptomatic-patients and 36 asymptomatic-patients with diabetic-neuropathy (DN) without CN underwent MDCT to assess CACS and severity of CAD. Patients were classified as positive for significant CAD in presence of at least one stenosis >50 % on MDCT-coronary-angiography (MDCT-CA). Groups were matched for age, sex and traditional CAD risk-factors. The coronary-angiography (CA) was performed in all patients with at least a significant stenosis detected by MDCT-CA, both as reference and eventually as treatment. RESULTS: CN patients showed higher rates of significant CAD in comparison with DN subjects [p < 0.001], while non-significant differences were observed in CACS (p = 0.980). No significant differences were also observed in CACS distribution in all subjects for stenosis ≥/<50 % (p = 0.814), as well as in both groups (p = 0.661 and 0.559, respectively). The MDCT-CA showed an overall diagnostic-accuracy for significant CAD of 87%. CONCLUSIONS: These preliminary data suggest that CN-patients have a higher prevalence of severe CAD in comparison with DN-patients, while coronary plaques do not exhibit an increased amount of calcium. MDCT may be helpful to assess the CV risk in such asymptomatic type-2-diabetic patients with autonomic-neuropathy. KEY POINTS: Type 2-diabetic-patients with CN result having more severe coronary artery plaque-burden. MDCT-CA may stratify the CV risk in type 2-diabetic-patients with CN. Adequate diagnostic is mandatory for optimal management of type 2-diabetic-patients with CN.

In the past, thoracic and cardiac imaging were two distinct specialties of radiology. The technical evolution, however, has changed their boundaries with an important impact on CT imaging practices and has opened the new era of "cardiothoracic" imaging, due to the strong anatomic, mechanical, physiologic, physiopathologic, and therapeutic cardiopulmonary correlations. Modern thoracic radiologists can no longer avoid the assessment of heart and coronary arteries, as they used to do with earlier generations of CT scanner. The advent of ECG gating and state-of-art CT scanner faster rotation speed, high spatial and temporal resolution, high-pitch mode, shorter acquisition time, and dedicated cardiac reconstruction algorithms has opened new possibilities for chest imaging, integrating cardiac morphologic and even functional information within a diagnostic chest CT scan. The aim of this review is to briefly show and summarize the concept of integrated cardiothoracic imaging, which redefines the boundaries of chest CT imaging, opening the door to a new radiologic specialty.
