BACKGROUND: Women with endometriosis often experience gastrointestinal symptoms. Gonadotropin-releasing hormone (GnRH) analogs are used to treat endometriosis; however, some patients develop gastrointestinal dysmotility following this treat…

In multicentre studies, measurements will vary between centres for various reasons (e.g. subjectivity of measurements, differences in equipment, deviations from the protocol and differences in patient populations). The aim of this interim a…

To estimate the prevalence of ultrasound features of adenomyosis in gynecologically asymptomatic premenopausal women 20–39 years old. This is a prospective observational study. 644 volunteers 20–39 years old recruited from a Swedish populat…

To assess ultrasonographic features of adnexal endometriomas in relation to patient age in premenopausal patients. Retrospective cross-sectional analysis of 5914 adnexal masses from the International Ovarian Tumor Analysis (IOTA) study. All…

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,…

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 en…

Transvaginal ultrasound plays a pivotal role in the management of non-pregnant women with abnormal vaginal bleeding. No other imaging technique has a role in the triage of these women. In women with postmenopausal bleeding, ultrasound is us…

To review the currently available literature regarding the role of ultrasonography in the management of uterine fibroids. Literature review of articles concerning the conservative treatment of uterine fibroids. Ultrasound examination allows…

BACKGROUND: To compare different ultrasound-based international ovarian tumour analysis (IOTA) strategies and risk of malignancy index (RMI) for ovarian cancer diagnosis using a meta-analysis approach of centre-specific data from IOTA3. ME…

OBJECTIVE: To estimate the diagnostic accuracy and interobserver agreement in predicting intracavitary uterine pathology at offline analysis of three-dimensional (3D) ultrasound volumes of the uterus. METHODS: 3D volumes (unenhanced ultras…

To describe the clinical history and ultrasound findings in women with decidualized endometriomas. Women with a histological diagnosis of decidualized endometrioma during pregnancy who had undergone preoperative ultrasound examination were …

OBJECTIVES: To describe the ultrasound characteristics of endometriomas in pre- and postmenopausal patients and to develop rules that characterize endometriomas. METHODS: All patients included in the International Ovarian Tumor Analysis (I…

OBJECTIVE: To determine the ability of acoustic streaming to discriminate between endometriomas and other adnexal masses. METHODS: We used data from 1938 patients with an adnexal mass included in Phase 2 of the International Ovarian Tumor …

This article summarises the ultrasound features of a number of gynaecological emergencies: ectopic pregnancy, haemorrhagic corpus luteum, twisted adnexa, pelvic inflammatory disease, acute myoma necrosis, haematocolpos and haematometra. The…

OBJECTIVES: To determine the sensitivity and specificity of subjective evaluation of gray-scale and Doppler ultrasound findings (here called pattern recognition) when used by experienced ultrasound examiners with regard to making a specific…

AIM: To evaluate the performance of subjective evaluation of ultrasound findings (pattern recognition) to discriminate endometriomas from other types of adnexal masses and to compare the demographic and ultrasound characteristics of the tru…

Haemorrhagic corpus luteum cysts are common causes of acute pelvic pain in women of fertile age. At ultrasound examination, corpus luteum cysts are characterised by spiderweb-like contents but they may also contain bizarre-looking blood clo…

To describe the US characteristics of masses that, based on pattern recognition, are presumed to be an endometrioma. The IOTA study included 3513 patients with an adnexal mass. All patients were scanned following the same US protocol. The U…

To define which US characteristics are suggestive for endometriosis and with which ultrasound features “atypical” endometriomas (Eomas) present. The IOTA study included 3513 patients with an adnexal mass. Histologically proven Eomas were in…

Acoustic streaming is the movement of fluid in a cyst due to energy transfer from the US wave. A previous study reported that absence of acoustic streaming could be a typical characteristic of an endometrioma (Eoma). The aim is to examine w…

To determine the diagnostic performance of subjective evaluation of ultrasound findings (pattern recognition) with regard to making a specific diagnosis in adnexal masses. Some 1066 patients in the International Ovarian Tumor Analysis study…

OBJECTIVES: To describe changes in endometrial and subendometrial volume and vascularity during the normal menstrual cycle using three-dimensional (3D) power Doppler ultrasonography. METHODS: Fourteen healthy volunteers, 24-44 years old wi…

This chapter summarizes the diagnostic performance (sensitivity, specificity, positive and negative likelihood ratios) of ultrasound, computer tomography, and magnetic resonance imaging in the diagnosis of various gynecological diseases and…

Pelvic pain (acute or chronic) is a common symptom in women of all ages. Ultrasonography is the least invasive investigative tool available to the clinician. Transvaginal probes produce high-resolution images of the pelvic organs, providing…
