O-RADS US Risk Stratification and Management System: A Consensus Guideline from the ACR Ovarian-Adnexal Reporting and Data System Committee.

The Ovarian-Adnexal Reporting and Data System (O-RADS) US risk stratification and management system is designed to provide consistent interpretations, to decrease or eliminate ambiguity in US reports resulting in a higher probability of accuracy in assigning risk of malignancy to ovarian and other adnexal masses, and to provide a management recommendation for each risk category. It was developed by an international multidisciplinary committee sponsored by the American College of Radiology and applies the standardized reporting tool for US based on the 2018 published lexicon of the O-RADS US working group. For risk stratification, the O-RADS US system recommends six categories (O-RADS 0-5), incorporating the range of normal to high risk of malignancy.

Three-Dimensional Volume Imaging in Gynecology.

3D ultrasound imaging of the female pelvis is one of the most important recent advances in diagnostic imaging. Volume acquisitions can provide a large number of images of the pelvic organs simultaneously and in any plane or orientation desired. The coronal plane of the uterus is only visible when reconstructed from a volume and is key to imaging the uterus for indications such as uterine anomalies, IUD positioning, locations of fibroids and polyps, or early pregnancies.

Simple Adnexal Cysts: SRU Consensus Conference Update on Follow-up and Reporting.

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 of cancer associated with simple adnexal cysts. Most small simple cysts do not require follow-up. For larger simple cysts or less well-characterized cysts, follow-up or second opinion US help to ensure that solid elements are not missed and are also useful for assessing growth of benign tumors.

Congenital Uterine Malformation by Experts (CUME): diagnostic criteria for T-shaped uterus.

Objectives: To identify uterine measurements that are reliable and accurate to distinguish between T-shaped and normal/arcuate uterus, and define T-shaped uterus, using Congenital Uterine Malformation by Experts (CUME) methodology, which uses as reference standard the decision made most often by several independent experts.

Methods: This was a prospectively planned multirater reliability/agreement and diagnostic accuracy study, performed between November 2017 and December 2018, using a sample of 100 three-dimensional (3D) datasets of different uteri with lateral uterine cavity indentations, acquired from consecutive women between 2014 and 2016. Fifteen representative experts (five clinicians, five surgeons and five sonologists), blinded to each others' opinions, examined anonymized images of the coronal plane of each uterus and provided their independent opinion as to whether it was T-shaped or normal/arcuate; this formed the basis of the CUME reference standard, with the decision made most often (i.

Intra- and Inter-Rater Agreement Describing Myometrial Lesions Using Morphologic Uterus Sonographic Assessment: A Pilot Study.

Objectives: To evaluate the intra- and inter-rater agreement for myometrial lesions using Morphologic Uterus Sonographic Assessment terminology.

Methods: Thirteen raters with high (n = 6) or medium experience (n = 7) assessed 30 3-dimensional ultrasound clips with (n = 20) and without (n = 10) benign myometrial lesions. Myometrial lesions were reported as poorly or well defined and then systematically evaluated for the presence of individual features.

Ovarian-Adnexal Reporting Lexicon for Ultrasound: A White Paper of the ACR Ovarian-Adnexal Reporting and Data System Committee.

Ultrasound is the most commonly used imaging technique for the evaluation of ovarian and other adnexal lesions. The interpretation of sonographic findings is variable because of inconsistency in descriptor terminology used among reporting clinicians. The use of vague terms that are inconsistently applied can lead to significant differences in interpretation and subsequent management strategies.

Obstetric and gynecologic ultrasound curriculum and competency assessment in residency training programs: consensus report.

Ultrasound imaging has become integral to the practice of obstetrics and gynecology. With increasing educational demands and limited hours in residency programs, dedicated time for training and achieving competency in ultrasound has diminished substantially. The American Institute of Ultrasound in Medicine assembled a multisociety task force to develop a consensus-based, standardized curriculum and competency assessment tools for obstetric and gynecologic ultrasound training in residency programs.

Proceedings: Beyond Ultrasound First Forum on Improving the Quality of Ultrasound Imaging in Obstetrics and Gynecology.

The Beyond Ultrasound First Forum was conceived to increase awareness that the quality of obstetric and gynecologic ultrasound can be improved, and is inconsistent throughout the country, likely due to multiple factors, including the lack of a standardized curriculum and competency assessment in ultrasound teaching. The forum brought together representatives from many professional associations; the imaging community including radiology, obstetrics and gynecology, and emergency medicine among others; in addition to government agencies, insurers, industry, and others with common interest in obstetric and gynecologic ultrasound. This group worked together in focus sessions aimed at developing solutions on how to standardize and improve ultrasound training at the resident level and beyond.

Diagnosis and management of patients with enhanced myometrial vascularity associated with retained products of conception.

Objectives: To assess the complication rate, including estimated amount of blood loss, in patients undergoing dilation and curettage (D&C) for the treatment of retained products of conception with markedly enhanced myometrial vascularity mimicking arteriovenous malformation.

Methods: This was a retrospective medical-records review study of patients with retained products of conception with enhanced myometrial vascularity presenting to our ultrasound unit between August 2015 and August 2017. Color/power Doppler imaging was used subjectively to identify the degree and extent of vascularity.

Counting ovarian antral follicles by ultrasound: a practical guide.

This Consensus Opinion summarizes the main aspects of several techniques for performing ovarian antral follicle count (AFC), proposes a standardized report and provides recommendations for future research. AFC should be performed using a transvaginal ultrasound (US) probe with frequency ≥ 7 MHz. For training, we suggest a minimum of 20-40 supervised examinations.

Congenital Uterine Malformation by Experts (CUME): better criteria for distinguishing between normal/arcuate and septate uterus?

Objectives: To assess the level of agreement between experts in distinguishing between septate and normal/arcuate uterus using their subjective judgment when reviewing the coronal view of the uterus from three-dimensional ultrasound. Another aim was to determine the interobserver reliability and diagnostic test accuracy of three measurements suggested by recent guidelines, using as reference standard the decision made most often by experts (Congenital Uterine Malformation by Experts (CUME)).

Methods: Images of the coronal plane of the uterus from 100 women with suspected fundal internal indentation were anonymized and provided to 15 experts (five clinicians, five surgeons and five sonologists).
