BACKGROUND: Conventionally, rectal endometriotic nodules have been considered as poorly vascularized. However, new, more sensitive, Doppler techniques have been developed recently for assessing microvascularization. These new techniques mig…

Transvaginal ultrasound is effective in diagnosing endometriosis involving the rectosigmoid bowel. Some authors suggest enhanced detection of rectosigmoid involvement with bowel preparation. Conversely, conflicting views argue that bowel pr…

In recent years, due to the development of standardized diagnostic protocols associated with an improvement in the associated technology, the diagnosis of pelvic endometriosis using imaging is becoming a reality. In particular, transvaginal…

OBJECTIVES: The aim of this study was to compare the accuracy of seven classical Machine Learning (ML) models trained with ultrasound (US) soft markers to raise suspicion of endometriotic bowel involvement. MATERIALS AND METHODS: Input dat…

In the present pictorial we show the ultrasonographic appearances of endometriosis in atypical sites. Scar endometriosis may present as a hypoechoic solid nodule with hyperechoic spots while umbilical endometriosis may appear as solid or pa…

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…

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…

OBJECTIVE: To estimate the diagnostic value of transvaginal ultrasonography in the detection of pelvic adhesions in women suspected of having endometriomas at ultrasonography. DESIGN: Prospective observational study. SETTING: Academic Dep…

OBJECTIVE: To evaluate the reproducibility and the accuracy of B-mode ultrasonographic features of three different kinds of benign ovarian cysts: ovarian endometrioma, mature teratoma, and serous cyst. METHODS: Digitally stored B-mode sono…

OBJECTIVE: To determine whether interleukin-8 (IL-8) serum levels are correlated with pelvic pain in patients with ovarian endometriomas. DESIGN: Prospective study. SETTING: Tertiary-care university hospital. PATIENT(S): Interleukin-8 se…

Vascular endothelial growth factor (VEGF) serum levels and VEGF and cellular expression were prospectively analyzed in 60 patients (group A consisted of asymptomatic patients or patients presenting mild dysmenorrhea; 30 women comprised grou…
