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…

The aim of a gynecological ‘one-stop bleeding clinic’ is to identify the cause of the bleeding and, if possible, to exclude endometrial carcinoma. Most of these outpatient clinics are based on the use of transvaginal sonography (TVS) with e…

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…

The presence of acoustic streaming in ovarian cysts can be determined by ultrasound imaging and provides an indication of the viscosity of the cyst content. It has previously been demonstrated that the absence of acoustic streaming in endom…

Although (sub)echogenic foci are common, especially after term pregnancy (T.Van den Bosch et al., Ultrasound Obstet Gynecol 2003; 22 (suppl 1):146–7), their histological correlate is not well established. Some authors hypothesized that smal…

OBJECTIVE: To assess the accuracy of new transvaginal ultrasound-scan-based markers and to compare them to conventional ultrasound methods used in the detection of common pelvic pathology in women with chronic pelvic pain (CPP). DESIGN: A …

An estimated one of every 10 gynecologic visits—and half of all diagnostic laparoscopies—are occasioned by chronic pelvic pain (CPP), a condition that often presents a difficult clinical problem. The most common disorders found at laparosco…

BACKGROUND: To evaluate the accuracy of transvaginal ultrasonography (TVS) for the detection of ectopic pregnancies (EPs) in women undergoing surgery for presumed ectopic pregnancy. METHODS: A prospective, observational study. Women were d…

Endometriosis is defined by the presence of endometrial tissue outside the uterus. Clinical and basic research in endometriosis has been hampered severely by the lack of accurate noninvasive diagnostic techniques. Transvaginal ultrasonograp…

To develop transvaginal ultrasound scan (TVS) based “soft markers” to improve the definition of a normal scan in women undergoing diagnostic laparoscopy for chronic pelvic pain (CPP). 120 consecutive patients had TVS 1–2 weeks before diagno…

To assess what factors in a patients history and which transvaginal ultrasound findings are most predictive of pathology in women with chronic pelvic pain (CPP). Prospective study. 120 consecutive women with CPP completed a questionnaire de…

To detect the presence and location of endometriosis in women undergoing diagnostic laparoscopy for chronic pelvic pain (CPP). Prospective study. 120 consecutive women with CPP had TVS 1–2 weeks before laparoscopy. All patients had a negati…

To evaluate the accuracy, user variability and impact of experience on the subjective assessment of transvaginal based soft markers in the evaluation of women with chronic pelvic pain undergoing laparoscopy. Prospective study. 38 consecutiv…

This review discusses uterine adenomyosis as a (co-)factor in female subfertility. The clinical presentation of adenomyosis uteri is reviewed as well as recent developments in non-invasive imaging modalities for the condition. Different tre…
