The association between endometriotic ovarian cysts (EOC) and deep infiltrating endometriosis (DIE) is well known, although DIE is still often under diagnosed. The objective of this study is to evaluate the performance of transvaginal ultra…

Due to the high sensitivity and specificity reported, the detection rate of rectosigmoid (RS) endometriosis by an ultrasonographic (US) evaluation of an expert have to be considered a gold standard comparable to laparoscopy. No information …

BACKGROUND: Methods available for assessing the learning curve, such as a predefined number of procedures or direct mentoring are lacking. Our aim was to describe the use of a statistical method to identify the minimal training length of an…

OBJECTIVES: To evaluate the diagnostic accuracy of 2-dimensional (2D) and 3-dimensional (3D) transvaginal ultrasonography (US) in comparison with magnetic resonance imaging (MRI) for identification of deep infiltrating endometriosis. METHO…

Objective To study the degree of interobserver agreement for already known two-dimensional (2D) and three-dimensional (3D) sonography criteria of adenomyosis. Methods Fifty cases (25 adenomyosis cases, 25 non-adenomyosis cases) were studied…

To assess if a structured off-line training program improves diagnostic performance of gynecologist in evaluation of patients with deep infiltrating endometriosis (DIE). A two week training program was conducted. One day was devoted to theo…

OBJECTIVE: To perform a systematic review of studies comparing the accuracy of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) in diagnosing deep infiltrating endometriosis (DIE) including only studies in which patients u…

STUDY QUESTION: Do sonographic characteristics of ovarian endometriomas vary with age in premenopausal women? SUMMARY ANSWER: With increasing age, multilocular cysts and cysts with papillations and other solid components become more common…

To assess the diagnostic performance of extended transvaginal ultrasound (EXTU) for diagnosing deep infiltrating endometriosis (DIE). Furthermore describe the use of high sliding sign for predict obliteration of pelvis and fixed ovaries. Pr…

OBJECTIVES: To review the diagnostic accuracy of transvaginal ultrasound (TVS) in the preoperative detection of rectosigmoid endometriosis in patients with clinical suspicion of deep infiltrating endometriosis (DIE), comparing enhanced (E-T…

OBJECTIVE: To review the diagnostic accuracy of transvaginal ultrasound (TVS) in the preoperative detection of endometriosis in the uterosacral ligaments (USL), rectovaginal septum (RVS), vagina and bladder in patients with clinical suspici…

Objective: To evaluate prospectively an ultrasound-based scoring system as a method for triaging symptomatic women presenting with an adnexal mass for surgical treatment. Methods: 151 symptomatic women scheduled for surgical treatment at ou…

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 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…

To evaluate the diagnostic accuracy of transvaginal ultrasound (TVUS) in the preoperative detection of deep endometriosis, using the pathologic and/or surgical data as a reference standard. An extensive search was performed in Medline (Pubm…

To compare two-dimensional ultrasonography (2DUS), three dimensional ultrasonography (3DUS) and magnetic resonance (MR) in the detection of deep endometriosis. The study included 147 patients scheduled for surgery from January 2009 to Decem…

OBJECTIVES: The purpose of this study was to assess the diagnostic performance of extended transvaginal sonography for diagnosing deep infiltrating endometriosis. METHODS: A prospective study was conducted comprising 51 women (mean age, 32…

Deep infiltrating endometriosis (DIE) is a disease that affects approximately 8–15% of fertile women. Because of this high prevalence, ultrasound examination has become a mainstay in clinical practice, which is supported by substantial evid…

Linked Comment: Ultrasound Obstet Gynecol 2014; 44: 710–718 The diagnosis of deep infiltrating endometriosis (DIE) by ultrasound has gained attention in the last decade. As a clinician, this is an important step forward in the management of…

The aim of the present study was to evaluate the diagnostic accuracy of three-dimensional (3D) ultrasonography in comparison with magnetic resonance imaging (MRI). This diagnostic test study included 117 patients scheduled for surgery becau…

To assess the diagnostic performance of extended transvaginal ultrasound (EXTU) for diagnosing deep infiltrating endometriosis (DIE) and use of high sliding sign for predict obliteration of pelvis and fixed ovaries. Further the use of low s…

STUDY QUESTION: In the use of 'tenderness-guided' transvaginal ultrasound, is the diagnostic accuracy of three-dimensional (3D) ultrasonography better than two-dimensional (2D) ultrasonography in the identification of deep endometriosis? S…

OBJECTIVE: To assess the diagnostic confidence of multiple readers in the magnetic resonance imaging (MRI) diagnosis of endometriosis. METHODS: Sixty-five patients (mean age 33; range 19-45 years) who had undergone MRI were retrospectively…

OBJECTIVE: To compare two different methods (manual sampling of the entire cyst and semi-automated spherical sampling from the central part of the cyst) for calculating the mean gray value (MGV) from the cystic content in endometriomas usin…
