MRI may provide alternative assessment of adnexal torsion. We evaluated an MRI appendicitis protocol for torsion identification.Methods: Retrospective chart and image review was performed for girls with appendicitis MRI exams from 2013 to 2019. Ovarian volumes, stromal T2 signal, and apparent diffusion coefficient (ADC) ratios were tabulated. Ovarian and paratubal cysts' size and location were recorded as well as presence or absence of torsion. Statistical analysis was performed.Results: Six hundred-fifty cases were included, eight with torsion. Higher ovarian volumes and volume ratios were found with torsion (p < 0.0001 and p < 0.0001, respectively). Ovarian volume ratio less than 4:1 had 99.7% negative predictive value (NPV). Ovarian volume less than 20 mL had 99.8% NPV. Five of six cases with 7 cm or larger adnexal cysts were torsed. T2 signal and ADC ratios overlapped between torsed and untorsed groups. No torsed adnexa appeared normal on MRI.Conclusion: Torsed cases tended to have larger ovaries and higher volume ratios. Adnexal cysts greater than 7 cm diameter were likely to be torsed. No torsion cases had normal adnexae on MRI. Normal appearing adnexae on MRI are very unlikely to be torsed.","PeriodicalId":11623,"journal":{"name":"Emergency Radiology","volume":" ","pages":"339-349"},"PeriodicalIF":1.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143992354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the effects of a CTPA protocol combining slow contrast medium injection and low tube voltage on radiation exposure and image quality.Methods: We retrospectively analyzed 82 patients undergoing CT scans for cancer treatment efficacy or follow-up, and simultaneous PTE exclusion. Patients were divided into two groups. Those in Group A (n = 43) received slow contrast injection (0.7-1.5 mL/s), and those in Group B (n = 39) received rapid injection (2.6-4.2 mL/s). All CT scans were performed using a multi-detector row CT scanner with optimized tube voltage and current settings. Contrast medium doses were adjusted based on the patient's body weight.Results: Group A had significantly lower radiation exposure compared with Group B. PTE was diagnosed in eight patients in Group A and seven in Group B, with no significant difference in prevalence rates. While Group B indicated higher mean CT values in the CTPA phase, the difference in the mean CT value of the pulmonary artery was only 29.6 Hounsfield units. Group A demonstrated superior contrast enhancement in parenchymal organs during the second phase.Conclusion: The slow-injection CTPA method proved effective for simultaneous PTE exclusion and cancer treatment evaluation, maintaining diagnostic accuracy with reduced risks associated with rapid injection.","PeriodicalId":11623,"journal":{"name":"Emergency Radiology","volume":" ","pages":"369-376"},"PeriodicalIF":1.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143514961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulation included 65 cases, with three focusing on orthopedic trauma: sacral ala, femoral neck, and pediatric tibial/Toddler's fractures. Faculty graded residents' responses using a standardized 10-point rubric and categorized errors as observational (failing to identify key findings) or interpretive (incorrect conclusions despite correct identification of findings).Results: 321 residents evaluated sacral ala fracture radiographs and received an average score of 1.29/10, with 8.71 points lost to observational errors. Only 6% produced effective reports (scores ≥ 7), while 80% made critical errors (scores < 2). For femoral neck fracture CT images (n = 316 residents), the average score was 2.48/10, with 6.71 points lost to observational errors. 25% produced effective reports, and 66% made critical errors. Pediatric tibial/Toddler's fracture radiographs (n = 197 residents) yielded an average score of 2.94/10, with 6.60 points lost to observational errors. 29% generated effective reports, while 71% made critical errors.Conclusion: Radiology residents demonstrated significant difficulty in identifying these orthopedic trauma cases, with errors primarily attributed to observational deficiencies. These findings suggest a need for targeted educational interventions in radiology residency programs to improve the identification of these fractures.","PeriodicalId":11623,"journal":{"name":"Emergency Radiology","volume":" ","pages":"387-394"},"PeriodicalIF":1.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142946562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advanced imaging techniques such as multidetector CT (MDCT) quickly provide detailed 3D images with high spatial resolution, making it ideal for rapid assessment of a variety of esophageal pathologies. This pictorial essay presents 10 illustrative cases to highlight the clinical applications of MDCT and its critical role in diagnosing conditions like perforation, foreign body impaction, inflammatory or infectious esophagitis, achalasia, fistulae, and neoplasms. Optimized CT protocols, such as contrast-enhanced imaging and advanced postprocessing techniques like maximum intensity projection (MIP) images and volumetric rendering technique (VRT), in addition to 3D cinematic rendering, are crucial in improving diagnostic accuracy and enhancing visualization of anatomical structures. The cases presented emphasize the importance of early detection and timely management of esophageal conditions, as small delays can lead to significantly increased morbidity and mortality. Ultimately, a multidisciplinary approach that coordinates clinical, radiological, and pathological evaluations ensures appropriate management and improved patient outcomes in esophageal emergencies.","PeriodicalId":11623,"journal":{"name":"Emergency Radiology","volume":" ","pages":"447-455"},"PeriodicalIF":1.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143973290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to determine if the hypoattenuating berry sign (HBS) can identify ruptured aneurysms in SAH patients with multiple aneurysms.Methods: Patients who had multiple aneurysms and underwent NECT were retrospectively recruited. The HBS, blood score, size and location of aneurysm were independently analyzed. The attenuation value of HBS and surrounding SAH were recorded. The independent factors of HBS in determination of ruptured aneurysms were analyzed using multivariable logistic regression.Results: Fifty-three patients (mean age 64.2 ± 10.9 years, 83.0% female) with 112 aneurysms were enrolled. In the univariate analysis, aneurysm size, aneurysm status (ruptured), and blood score were significantly correlated with the occurrence of HBS. In the multivariate analysis, only aneurysm status showed a significant association with HBS. Aneurysms with HBS were larger than those without (6.8 ± 4.2 mm versus 4.2 ± 1.2 mm, P < 0.001), and those measured via NECT were larger than those measured via DSA (7.2 ± 3.8 mm vs. 6.8 ± 4.2 mm, P < 0.001). HBS was found in 51.8% of all aneurysms and in 87.7% of ruptured aneurysms on NECT. Raters had high agreement on aneurysm size (ICC = 0.829), HBS presence (kappa = 0.928), and blood score (kappa = 0.780).Conclusions: The HBS can be used to detect ruptured aneurysm in patient with SAH and multiple aneurysms.","PeriodicalId":11623,"journal":{"name":"Emergency Radiology","volume":" ","pages":"361-368"},"PeriodicalIF":1.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143398577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Summary statistics, correlation, and regression analyses were performed.Results: A total of 164 physicians participated, with an average age of 33.8 (± 7.69) years; 52.4% were radiologists and 47.6% were emergency physicians. Participants exhibited good knowledge, attitudes, and confidence. Higher attitude scores (β = 0.28; p < 0.001) and having a POCUS machine (β = 1.70; p = 0.01) were associated with higher knowledge. Higher knowledge (β = 0.64; p < 0.001) predicted better attitudes, while attitude (β = 0.21; p = 0.01), specialty radiologist (β = 8.5; p < 0.001), age (β = 0.23; p < 0.001), and number of monthly scans (β = 0.01; p = 0.01) predicted confidence.Conclusion: Radiologists and emergency physicians in Jordan demonstrated good POCUS knowledge, attitudes, and confidence.
