The role of ultrasound differs considerably across the 6 cancers. In cases of endometrial and GTD, ultrasound is used to guide initial diagnosis, risk stratification, and surgical planning. In postmenopausal bleeding, a transvaginal ultrasound can assess endometrial thickness and determine the need for further evaluation. In cervical cancer, transrectal ultrasound allows local tumor assessment and brachytherapy guidance. Ovarian and fallopian tube cancers rely on ultrasound as the first-line tool for adnexal mass assessment and contribute to the Risk of Malignancy Index. For vaginal cancer, sonography has a complementary role in the anatomic assessment of the primary tumor. In vulvar cancer, ultrasound use is limited, as it is mainly for lymph node evaluation in early disease, when used in conjunction with clinical examination and cross-sectional imaging. Although ultrasound has limitations when assessing nodal spread or distant metastases, it can be used in combination with cross-sectional imaging and serial biomarkers to provide a complete evaluation. This review aims to summarize the ultrasound-relevant content from the 2025 FIGO update reports and serve as a practical reference for radiologists.","PeriodicalId":49116,"journal":{"name":"Ultrasound Quarterly","volume":"42 2","pages":""},"PeriodicalIF":1.1,"publicationDate":"2026-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148007089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study retrospectively reviewed the clinical records of patients who underwent US-CNB or EUS-FNA biopsy for pancreatic lesions between January 2019 and 2022. For each patient, demographic information and information on lesion size, location, and type were obtained. A total of 229 subjects were recruited into the study, with 140 in the US-CNB group and 89 subjects in the EUS-FNA group. The results revealed higher diagnostic efficiency in the US-CNB group compared with the EUS-FNA group, with efficiencies of 96.4% and 70.8%, respectively (P<0.001). Multivariate logistic regression showed that, after adjusting for confounders, US-CNB remained an independent predictor (OR=3.051, P=0.011). After propensity score matching, US-CNB continued to demonstrate significantly higher diagnostic efficiency compared with EUS-FNA (98.4% vs. 71.0%, P<0.001). Diagnostic performance parameters were evaluated in 105 patients with histopathologically established final diagnosis and at least 1 year of follow-up. In addition, US-CNB demonstrated higher sensitivity and specificity when compared with EUS-FNA, which were 92.7% and 83%, respectively. In this retrospective cohort, US-CNB demonstrated higher sample adequacy and sensitivity compared with EUS-FNA for the diagnosis of pancreatic lesions.

Currently, there is an unmet need for practical tools that help trainees reliably detect pneumonia-related ultrasound findings. In this technical innovation study, we evaluated a semi-automated, artificial intelligence (AI)-assisted system designed to identify clinically relevant lung abnormalities, including pleural line thickening, consolidation morphology, and B-line patterns. Our computerized analysis demonstrated the system's technical capability to accurately detect these structural changes with minimal user interaction. Although our primary aim was to assess diagnostic feasibility, the intuitive nature and real-time visual annotations provided by this AI tool highlight its strong potential for future integration into educational contexts.

A retrospective analysis was conducted at Mayo Clinic's Florida and Arizona campuses, including 200 premenopausal and perimenopausal women with chronic pelvic pain, infertility, or suspected endometriosis. Sonographers performed a uterine sliding maneuver during transvaginal ultrasound, and the acquisition times were recorded. Sonographer experience and the time required to perform the sliding sign were analyzed using Microsoft Excel. The median acquisition time for the uterine sliding sign was 26 seconds, with no statistically significant difference based on sonographer experience. The addition of this maneuver extended the ultrasound examination by <1 minute on average, regardless of sonographer experience level. Incorporating the uterine sliding sign into routine pelvic ultrasound protocols is a quick and efficient method that enhances the detection of deep endometriosis, potentially reducing the significant diagnostic delay associated with endometriosis.

Cases identified between 2016 and 2023 were reviewed for demographic, clinical, and imaging features on computed tomography (CT), magnetic resonance imaging (MRI), and US. Seven patients (6 male, 1 female; mean age 61 ± 8 y) were included, with presentations of abdominal pain (n=2), hematuria (n=1), and incidental detection (n=4). The mean maximal tumor diameter was 2.4 cm (range: 1.4-4.8 cm); 6 lesions were round and 1 was bilobed. On CT, masses demonstrated low attenuation (mean 15 HU) with variable enhancement (mean 23 HU). MRI in 5 cases demonstrated predominantly T1 hypointense and T2 hyperintense lesions, with 1 lesion showing mixed T2 signal intensity; 3 cases showed enhancement, including septa or a mural nodule. Two hyperechoic lesions demonstrated enhancement on MRI, with enhancement corresponding to the hyperechoic portions of the mixed echogenic mass. US in 5 cases showed 3 uniformly hyperechoic, 1 mixed echogenic, and 1 septated hypoechoic mass, all demonstrating posterior acoustic enhancement. CEUS in 1 case revealed septal enhancement. Although CT and MRI features may mimic cysts, US most commonly demonstrates a hyperechoic lesion with posterior acoustic enhancement and may provide important additional diagnostic information when other imaging findings are equivocal.","PeriodicalId":49116,"journal":{"name":"Ultrasound Quarterly","volume":"42 2","pages":""},"PeriodicalIF":1.1,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147787026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This pilot study evaluated the reliability of rectus femoris (RF) muscle US measurements [cross-sectional area (CSA) and shear-wave elastography (SWE) stiffness] and investigated their relationship with CT-derived truncal muscle mass. Forty healthy living liver donors undergoing abdominal CT were included. CT-derived skeletal muscle area and skeletal muscle index at T12 and L3 were quantified using deep learning. US B-mode and SWE RF images obtained with manual and automated measurements. Reliability was assessed using intraclass correlation (ICC). Agreement between manual and automated methods was evaluated using the Dice coefficient. US and CT measurements associations were evaluated using Pearson correlation and multiple linear regression. Inter-reader agreement for manual US CSA was excellent (ICC=0.95, 95% CI: 0.88-0.97). Test-retest reliability of SWE was good (ICC=0.78, 95% CI: 0.67-0.87). Automated and manual methods showed strong agreement (Dice coefficient 0.94) and good reliability (ICC=0.85, 95% CI: 0.75-0.91).
