To evaluate reproductive results of patients presenting adenomyosis under Morphological Uterus Sonographic Assessment (MUSA) criteria who underwent assisted reproductive techniques (ART) using oocyte donation or preimplantation genetic test…

BACKGROUND: Transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) are used for the clinical diagnosis of adenomyosis. OBJECTIVES: To compare the diagnostic accuracy of TVS and MRI for the diagnosis of adenomyosis. SEARCH STRA…

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 evaluate the accuracy of transvaginal sonography (TVS) for detecting parametrial deep endometriosis, using laparoscopy as the reference standard. METHODS: A search was performed in PubMed/MEDLINE and Web of Science for studie…

The role of ultrasound in the detection of the parametrial localisation of deep endometriosis although associated with ureteral stenosis and linked with a complex surgery with a high risk of intra and post-operative complications, is poor i…

To determine the pooled recurrence rate of benign adnexal masses/cysts (namely simple cyst, endometrioma, hydrosapinx, peritoneal cyst) after transvaginal ultrasound-guided aspiration, with or without sclerotherapy. A search of studies publ…

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: To analyze the reproducibility of ultrasonographic (US) findings of rectosigmoid endometriosis among examiners with different level of expertise using stored three-dimensional (3D) volumes of the posterior compartment of the pelv…

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 endometriosis of uterosacral ligaments. Input data to the models was retrieved…

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 forniceal endometriotic involvement. Input data to the models was retrieved fr…

Two main theories have been proposed to explain the origin of adenomyosis. The first theory postulated that adenomyosis results from invagination of the endometrial basalis into the myometrium as a repair mechanism after injury. Alternative…

Uterine contractions may affect the thickness and features of the myometrial wall as well as the shape of the uterine cavity. The transient nature of these changes can be appreciated during real-time two-dimensional ultrasound examination a…

The aim of this study was to evaluate the use of ultrasound (US) soft markers to raise suspicion of uterosacral involvement in women suspected of having deep endometriosis. We included in this prospective observational study all patients wi…

Objective: To determine whether Vitamin D serum levels are correlated with pelvic pain in patients with ovarian endometriomas. Design: Prospective study. Setting: Tertiary-care university hospital. Patient(s): vitamin D serum le…

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…

The aim of this study was to evaluate the use of ultrasound (US) soft markers as a first-line imaging tool to raise suspicion of forniceal involvement in women suspected of having deep endometriosis. We included in this prospective observat…

To analyse the reproducibility of ultrasonographic (US) findings of rectosigmoid endometriosis among examiners with different level of expertise using stored 3D volumes of posterior compartment of the pelvis as a part of SANABA (Sardinia-Na…

the aim of this study was to compare the accuracy of seven classical machine learning models of ultrasound (US) soft markers in raising suspicion of bowel involvement using a dataset with previously published results. The data driven strate…

To assess non-expert interobserver agreement for sonographic diagnosis of adenomyosis. 47 videoclips and 3D volumes (25 cases with adenomyosis and 22 cases without adenomyosis according to expert subjective impression) were evaluated by one…

This chapter reviews ultrasound findings related to primary dysmenorrhea and adenomyosis. Dysmenorrhea is defined as the presence of painful cramps of uterine origin during menstruation and constitutes one of the most common problems in wom…

Pelvic pain is a common complaint in women of all ages and may be due to many different causes. Whatever the cause of the pain, a thorough clinical history and physical examination is mandatory. Pelvic pain may be acute or chronic. This cha…

OBJECTIVES: The aim of this study was to evaluate the use of ultrasound (US) soft markers as a first-line imaging tool to raise suspicion of rectosigmoid (RS) involvement in women suspected of having deep endometriosis. METHODS: We include…

OBJECTIVE: To assess the learning curves of trainees during a structured offline/hands-on training program for the ultrasonographic diagnosis of deep infiltrating endometriosis (DIE). METHODS: Four trainees (all Ob/Gyn postgraduates with a…
