Endometriosis is a chronic condition affecting approximately 1 in 10 women of childbearing age, significantly impacting their daily lives, mental health, and quality of life. This study explores the relationship between chronic pain, patien…

BACKGROUND: Over the past decade, transvaginal ultrasound (TVUS) has revolutionized the diagnosis of deep endometriosis. We can now accurately describe and evaluate lesions in multiple compartments of the pelvis, increasing diagnostic capac…

OBJECTIVE: The aim of the study was to evaluate the diagnostic accuracy for parametria endometriosis (PE) of transvaginal sonography (TVS) performed following a systematic approach for the assessment of the lateral parametria. DESIGN: A di…

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…

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…

OBJECTIVE: To determine the pooled recurrence rate of benign adnexal masses/cysts (namely simple cyst, endometrioma, hydrosalpinx, peritoneal cyst) after transvaginal ultrasound-guided aspiration, with or without sclerotherapy. DATA SOURCE…

OBJECTIVE:: Some recent studies have explored how the experience in the observers change their performance in the endometriosis detection using MRI but the effects of the clinical information remains uncertain. The purpose of this study was…

INTRODUCTION: Endometriosis is a hormone-dependent benign chronic disease that requires a chronic medical therapy. Although currently available drugs are efficacious in treating endometriosis-related pain, some women experience partial or n…

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…

INTRODUCTION: Suppression of sex-steroid secretion is required in a variety of gynecological conditions. This can be achieved using gonadotropin releasing hormone (GnRH) agonists that bind pituitary gonadotropin receptors and antagonize the…

1To whom correspondence should be addressed We studied the role of colour Doppler energy (CDE) (or power Doppler) imaging in the differentiation between endometriomas and other adnexal masses in premeno-pausal non-pregnant women. A total of…

Deep pelvic endometriosis is defined as subperitoneal infiltration of endometrial implants in the uterosacral ligaments, rectum, rectovaginal septum, vagina, or bladder. Although laparoscopy and biopsy remain the gold standard for diagnosis…

Several imaging options are available today to diagnose endometriosis. Currently, the two techniques most used are sonography and magnetic resonance imaging (MRI). Three-dimensional (3D) sonography has proved to be particularly sensitive in…

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…

Among gynecological malignancies, ovarian cancer is the most frequent cause of death. Image mining algorithms have been predominantly used to give the physicians a more objective, fast, and accurate second opinion on the initial diagnosis m…

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…

OBJECTIVES: The aim of this study was to evaluate the interobserver agreement for diagnosis of deep endometriosis of the rectovaginal septum using introital 3-dimensional (3D) sonography. METHODS: Two experienced observers (observers A and…

The diagnosis rate of deep pelvic endometriosis is increasing. Endometrial stromal sarcoma (ESS) is a rare neoplasm. Extragenital ESS is an extremely uncommon event. Very few cases of extragenital ESS have been reported to date. The diagnos…

PURPOSE: To compare the diagnostic accuracy of MRI and "tenderness-guided" transvaginal ultrasonography (tg-TVUS) in the identification of recto-sigmoid endometriosis. MATERIALS AND METHODS: Institutional Review Board approval for this stu…

OBJECTIVES: The purpose of this study was to assess whether a single determination of the serum cancer antigen 125 (CA-125) level provides additional information to sonography for specific diagnosis of benign adnexal masses in premenopausal…

In this study we aimed to assess the diagnostic accuracy of transvaginal ultrasound for assigning a specific diagnosis to benign adnexal masses in pre- and postmenopausal women. The study comprised 2146 adnexal masses in 1980 women. 1420 wo…

BACKGROUND: Magnetic resonance imaging (MRI) is a promising technique in the study of endometriosis, allowing a complete mapping of lesions before surgery. However, the value of MRI in the diagnosis of endometriosis in the bladder, in super…

OBJECTIVE: To evaluate the diagnostic accuracy of introital three-dimensional (3D) transvaginal sonography for preoperative detection of rectovaginal septal endometriosis. DESIGN: Ultrasonographic results were compared with surgical and hi…

PURPOSE: Determining if Magnetic Resonance Imaging (MRI) accuracy in diagnosing endometriosis is related to radiologist's expertise. METHODS AND MATERIALS: Written informed consent was obtained from all patients. This study is compliant to…
