The Ovarian-Adnexal Reporting and Data System (O-RADS) US risk stratification management system is designed to provide consistent interpretations, decrease or eliminate ambiguity in reports resulting a higher probability of accuracy assigning malignancy ovarian other adnexal masses, recommendation for each category. It was developed by an international multidisciplinary committee sponsored the American College Radiology applies standardized reporting tool based on 2018 published lexicon...

PURPOSE: To compare ultrasonography (US), magnetic resonance (MR) imaging, and computed tomography (CT) for diagnosing staging advanced ovarian cancer. MATERIALS AND METHODS: US, CT, MR imaging were performed in 280 patients. Images read by three radiologists from each of the five hospitals. Image analysis included determination malignancy within peritoneum (11 sites), lymph nodes (10 hepatic parenchyma. The standard reference was based on surgical histopathologic findings. Statistical...

To determine the optimal imaging modality for diagnosis and staging of ovarian cancer.Two hundred eighty women suspected to have cancer were enrolled in a prospective study before surgery. Doppler ultrasonography (US), computed tomography (CT), magnetic resonance (MR) used evaluate mass; conventional US, CT, MR stage spread.All three modalities had high accuracy (0.91) overall malignancy. In ovaries, was higher than that CT significantly US (0.78). extraovarian pelvis abdomen, similar...

Ultrasound (US) is an extremely useful diagnostic imaging modality because of its real-time capability, noninvasiveness, portability, and relatively low cost. It carries none the potential risks ionizing radiation exposure or intravenous contrast administration. For these reasons, numerous medical specialties now rely on US not only for diagnosis guidance procedures, but also as extension physical examination. In addition, many school educators recognize usefulness this technique aid to...

The First International Consensus Conference on Adnexal Masses was convened to thoroughly examine the state of science and formulate recommendations for clinical assessment management. panel included representatives societies in fields gynecology, gynecologic oncology, radiology, pathology clinicians from Europe, Canada, United States. In States, there are approximately 9.1 surgeries per malignancy compared European Ovarian Tumor Analysis center trials, with only 2.3 (oncology centers) 5.9...

PURPOSE: To determine whether color and pulsed Doppler ultrasound (US) can be used to differentiate benign from malignant ovarian masses. MATERIALS AND METHODS: Forty-four masses identified with sonography in 40 patients were confirmed at surgery (n = 35) or followed up resolution US 9). Color calculate the lowest pulsatility index (PI) resistance (RI) for each mass. RESULTS: enabled detection of arterial flow 24 36 six eight PI was lower than (P .002), as RI .001). Both indexes demonstrated...

This multidisciplinary consensus update aligns prior Society of Radiologists in Ultrasound (SRU) guidelines on simple adnexal cysts with recent large studies showing exceptionally low risk cancer associated cysts. Most small do not require follow-up. For larger or less well-characterized cysts, follow-up second opinion US help to ensure that solid elements are missed and also useful for assessing growth benign tumors. In postmenopausal women, reporting greater than 1 cm should be done...

Obstetric sonograms of 26 fetuses with echogenic material in the gallbladder were reviewed to describe sonographic findings and clinical significance. Gestational age at time diagnosis ranged from 28 42 weeks (mean, 36.2 weeks). The foci associated distal shadowing eight (30%), comet-tail artifact nine (35%), no (35%). No hemolytic anemias, other predisposing risk factors, or sequelae biliary tract disease identified any infants. Postnatal pathologic follow-up studies available 17 cases. In...

Ovarian stromal hyperthecosis (SH) has variable clinical importance but can cause hyperandrogenism, particularly in premenopausal women. Sonography is often used to evaluate the ovaries of women with there little published regarding sonographic appearance SH. The primary purpose this study was describe features SH.A computerized search our institution's pathology and imaging databases from 1996 through 2007 performed identify patients histologically proven SH who had pelvic sonography before...

Premenopausal women who present with acute pelvic pain frequently pose a diagnostic dilemma, exhibiting nonspecific signs and symptoms, the most common being nausea, vomiting, leukocytosis. Diagnostic considerations encompass multiple organ systems, including obstetric, gynecologic, urologic, gastrointestinal, vascular etiologies. The selection of imaging modality is determined by clinically suspected differential diagnosis. Thus, careful evaluation such patient should be performed narrowed...

Adnexal masses are a common problem clinically and imaging-wise, transvaginal US (TVUS) is the first-line imaging modality for assessing them in vast majority of patients. The findings US, however, should be correlated with history laboratory tests, as well any patient symptoms. Simple cysts uniformly benign, most warrant no further interrogation or treatment. Complex carry more significant implications, usually engender serial ultrasound(s), minority cases warranting pelvic MRI....
