The most prevalent findings were as follows: in the abdomen-obstructive uropathy (in 12.2%), pyelonephritis (in 6.4%), cholecystitis (in 5.8%), and enterocolitis (in 5.8%); in the chest-pneumonia (in 23.7%), pleural effusion (in 12.9%), and pulmonary contusion (in 5.4%); and in the head-extracranial soft tissue edema (in 11.9%), stroke (in 10.7%), and brain contusion (in 7.9%).Conclusion: Our findings demonstrate the importance of using CT for proper diagnosis and clinical management in emergency departments. Our data also contribute to establishing the most prevalent radiological findings in each anatomical region, thus promoting rapid, efficient clinical practice in emergency settings.","PeriodicalId":20842,"journal":{"name":"Radiologia Brasileira","volume":"57 ","pages":"e20240068"},"PeriodicalIF":0.0,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11737095/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143010507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A single observer quantified the thickness of the extraocular muscles and the degree of proptosis. Clinical and biochemical variables were analyzed to determine whether they correlated with CT changes, GO activity, and GO severity.Results: Our sample included data from 67 patients with GO (134 orbits), 50 (74.6%) of whom were female. There were positive correlations between the clinical activity score and increase in thyroid-stimulating factor/free thyroxine, between the severity of GO and the increase in the thickness of the extraocular muscles, and between the degree of proptosis and muscle thickness.Conclusion: Orbital CT proved effective in detecting thickening of the extraocular muscles and proptosis in patients with GO, changes that correlated significantly with clinical and biochemical variables. Muscle thickening was associated with the severity of GO and could be a biomarker of the risk of vision loss.","PeriodicalId":20842,"journal":{"name":"Radiologia Brasileira","volume":"57 ","pages":"e20240040en"},"PeriodicalIF":0.0,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11734998/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143010498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The following ultrasound examinations were performed: soft tissue, thyroid, cervical, breast, transvaginal, pelvic gynecology, total abdomen, upper abdomen, and kidney/urinary tract in B-mode, with color Doppler, or both.Results: The sample consisted of 478 women who underwent 1,274 ultrasound examinations. The mean age was 40.0 years (range, 22-73 years). Over half (58.2%) of the women were single, 50.2% were White, and 59.6% self-identified as heterosexual. An ultrasonographic finding of uterine myoma was associated with older age (p = 0.022), higher body mass index (p = 0.022), and being tattooed (p = 0.040). An ultrasonographic finding of simple ovarian cyst was associated with sexual orientation (p = 0.020), whereas a finding of adenomyosis were associated with older age (p = 0.012). An ultrasonographic finding of polycystic ovaries was associated with younger age (p < 0.001). The most common ultrasonographic findings were uterine myoma (in 13.6%), biliary lithiasis (in 13.4%), and renal lithiasis (in 11.5%).Conclusion: The most common ultrasonographic findings in female inmates were uterine myoma, biliary lithiasis, and renal lithiasis.","PeriodicalId":20842,"journal":{"name":"Radiologia Brasileira","volume":"57 ","pages":"e20240086"},"PeriodicalIF":0.0,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11630634/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142807900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single or multiple FBs may be retained at different sites including the gastrointestinal tract, the genitourinary system, the respiratory tract, and the soft tissues, all of which warrant medical attention. More importantly, ensuing, serious complications related to harmful positioning of these objects can significantly hamper normal function of any involved organ system. Because various FBs may be detected throughout the body, it is important that radiologists are also familiar with a myriad of life-threatening complications associated with retained items, including impaction, obstruction, perforation, hemorrhage, embolization, chemical dissolution, poisoning, and sepsis. Imaging plays a key role in the detection, localization, and characterization of FBs. Radiologists need to describe in exhaustive detail suspected items with regard to the anatomical location, type, shape, and composition of the object under investigation. Clinicians can then predict whether the foreign object(s) will pass through the body uneventfully or need to be addressed in a surgical procedure.","PeriodicalId":20842,"journal":{"name":"Radiologia Brasileira","volume":"57 ","pages":"e20240057"},"PeriodicalIF":0.0,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11630635/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142807827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
