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. In postmenopausal women, reporting of simple cysts greater than 1 cm should be done to document their presence in the medical record, but such findings are common and follow-up is recommended only for simple cysts greater than 3-5 cm, with the higher 5-cm threshold reserved for simple cysts with excellent imaging characterization and documentation...

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...

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. The curriculum and competency assessment tools were developed based on existing national and international guidelines for the performance of obstetric and gynecologic ultrasound examinations and thus are intended to represent the minimum requirement for such training...

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...

Immune response (Ir) genes, originally proposed by Baruj Benacerraf to explain differential antigen-specific responses in animal models, have become synonymous with the major histocompatibility complex (MHC). We discovered a non-MHC-linked Ir gene in a T cell receptor (TCR) locus that was required for CD8+ T cell responses to the Plasmodium berghei GAP5040-48 epitope in mice expressing the MHC class I allele H-2Db . GAP5040-48 -specific CD8+ T cell responses emerged from a very large pool of naive Vβ8.1+ precursors, which dictated susceptibility to cerebral malaria and conferred protection against recombinant Listeria monocytogenes infection...

The IDEA (International Deep Endometriosis Analysis group) statement is a consensus opinion on terms, definitions and measurements that may be used to describe the sonographic features of the different phenotypes of endometriosis. Currently, it is difficult to compare results between published studies because authors use different terms when describing the same structures and anatomical locations. We hope that the terms and definitions suggested herein will be adopted in centers around the world. This would result in consistent use of nomenclature when describing the ultrasound location and extent of endometriosis...

The MUSA (Morphological Uterus Sonographic Assessment) statement is a consensus statement on terms, definitions and measurements that may be used to describe and report the sonographic features of the myometrium using gray-scale sonography, color/power Doppler and three-dimensional ultrasound imaging. The terms and definitions described may form the basis for prospective studies to predict the risk of different myometrial pathologies, based on their ultrasound appearance, and thus should be relevant for the clinician in daily practice and for clinical research...

The idiotypes expressed by T cells involved in responses to a particular antigen are very similar to those on immunoglobulin (Ig) molecules specific for the same antigen. However, the T-cell antigen receptors do not use the same variable region genes as the Ig heavy chain molecules. Here, Kent HayGlass and his colleagues review the evidence for this interesting puzzle and suggest that the idiotypes expressed by 8 cells to which maturing T cells are exposed determine the final T-cell idiotype repertoire.

OBJECTIVE: To evaluate the performance of first-trimester nuchal translucency (NT) measurement by providers (physician-sonologists and sonographers) within the Nuchal Translucency Quality Review (NTQR) program. METHODS: After training and credentialing providers, the NTQR monitored performance of NT measurement by the extent to which an individual's median multiple of the normal median (MoM) for crown-rump length (CRL) was within the range 0.9-1.1 MoM of a published normal median curve...

OBJECTIVES: To describe the clinical history and ultrasound findings in women with decidualized endometriomas surgically removed during pregnancy. METHODS: In this retrospective study, women with a histological diagnosis of decidualized endometrioma during pregnancy who had undergone preoperative ultrasound examination were identified from the databases of seven ultrasound centers. The ultrasound appearance of the tumors was described on the basis of ultrasound images, ultrasound reports and research protocols (when applicable) by one author from each center using the terms and definitions of the International Ovarian Tumor Analysis (IOTA) group...

Prenatal detection of fetal anomalies is one of the major goals of obstetrical ultrasound. The primary reason is the options that are often offered to the family and caregivers from therapy in selected cases to special care at delivery to termination of the pregnancy. An important aspect of the diagnosis is to determine whether the anomaly is expected to be lethal or associated with severe physical or mental impediments. This goal is often difficult to accomplish without a clear diagnosis. A systematic approach is essential when an abnormality is first identified sonographically to help the practitioner discover certain patterns of associated defects...

The Society of Radiologists in Ultrasound (SRU) convened a panel of specialists from gynecology, radiology, and pathology to arrive at a consensus regarding the management of ovarian and other adnexal cysts imaged sonographically in asymptomatic women. The panel met in Chicago, IL, on October 27-28, 2009, and drafted this consensus statement. The recommendations in this statement are based on analysis of current literature and common practice strategies, and are thought to represent a reasonable approach to asymptomatic ovarian and other adnexal cysts imaged at ultrasonography...
