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}

We evaluated three different strategies measures for quantification of hepatic steatosis in two matched groups: homogeneous and heterogeneous steatosis. We considered p < 0.05 significance level in all made tests.Results: In heterogeneous steatosis group, the strategy with a region of interest (ROI) of 1 cm2 to measure the signal intensity in the most altered area showed significant variations in the quantification, while the average of four ROIs of 1 cm2 or representative target area in axial section did not vary significant. In diffuse hepatic steatosis, any strategy used showed no significant difference. The intraclass correlation coefficient ranged between 0.96 and 0.99, with 95% confidence interval of 0.93-0.99.Conclusion: The quantification of fat liver by magnetic resonance imaging using only one ROI is less representative, especially in heterogeneous steatosis.
