An observational study in Endometriosis, Adenomyosis of Uterus and Leiomyoma (Uterine Fibroids), sponsored by Semmelweis University. Recruiting at 1 site in Hungary. Open to female participants aged 18 Years to 45 Years. Per ClinicalTrials.gov, last updated 2026-09-18.
Sponsored by Semmelweis University · Observational
The goal of this observational study is to develop and validate artificial intelligence (AI)-based algorithms that support ultrasound diagnosis of endometriosis, adenomyosis, myometrial masses, uterine malformations, and impaired endometrial receptivity in women aged 18-45 years. The main questions it aims to answer are:
Can AI algorithms, applied to standardized transvaginal ultrasound images, accurately detect and classify endometriosis and adenomyosis in real time during routine examination? Can AI-based ultrasound assessment predict the histological dignity of myometrial masses, and the likelihood of successful assisted reproduction (AR/IVF) outcome from endometrial features?
Participants attending the Department of Obstetrics and Gynecology, Semmelweis University, with clinical suspicion of endometriosis or adenomyosis, a confirmed myometrial mass scheduled for surgery, a suspected uterine anomaly, or scheduled IVF treatment, will undergo standardized transvaginal ultrasound examination (following the IDEA, MUSA, and IETA protocols) alongside collection of clinical, questionnaire, and, where surgery is performed, histopathological data. Imaging and clinical data will be used to build a database supporting the development and validation of the AI algorithms.
920 studies on the registry are indexed under Endometriosis; 266 are open to participants now.
This study's planned enrollment of 1,600 is above the median of 135 across 349 observational studies indexed under Endometriosis.

The study population comprises patients aged 18-45 years who attend the Department of Obstetrics and Gynecology at Semmelweis University. A total of 1600 participants will be enrolled: 1200 for the endometriosis/adenomyosis cohort, 200 for the myometrial mass dignity-prediction cohort, and 200 for the cohort addressing other benign infertility-related conditions and AR/IVF outcome prediction.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Women aged 18-45 years with clinical suspicion of endometriosis, in whom the diagnosis is subsequently confirmed by laparoscopy or laparotomy with histological analysis of the resected specimen (peritoneal, ovarian, or deep infiltrating endometriosis). No intervention is administered; participants undergo a standardized transvaginal ultrasound examination (IDEA protocol) and complete clinical and quality-of-life questionnaires (NRS, EHP-30) as part of routine care.
Women aged 18-45 years with clinical suspicion of adenomyosis, assessed by standardized transvaginal ultrasound (MUSA protocol) for direct and indirect sonographic features, morphological subtype, and severity. No intervention is administered; assessment occurs as part of routine gynecological care.
Women aged 18-45 years with a previously confirmed uterine leiomyoma scheduled for surgical treatment. Participants undergo standardized ultrasound assessment of leiomyoma location, size, and sonographic features prior to surgery, with post-surgical histopathological correlation. No intervention is administered beyond standard-of-care surgical treatment already planned.
Women aged 18-45 years undergoing ultrasound examination for suspected congenital (Müllerian) uterine anomaly or other intracavitary uterine pathology. Participants undergo standardized ultrasound assessment; no intervention is administered.
Women aged 18-45 years scheduled for IVF treatment or embryo transfer, without confirmed uterine or endometrial pathology other than adenomyosis. Participants undergo standardized ultrasound assessment of endometrial thickness, morphology, and vascularity (IETA protocol) around the window of implantation, linked to subsequent assisted reproduction treatment and pregnancy outcome. No intervention is administered.
Diagnostic accuracy of the AI algorithm for detection of endometriosis and adenomyosis on transvaginal ultrasound
Sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) of the AI-based detection algorithm for endometriosis and adenomyosis, assessed against the reference standard of surgical findings and histopathological confirmation (for participants undergoing surgery) or, where surgery is not performed, expert consensus review of the standardized ultrasound examination.
Time frame: 3 years
Plan to share: No — The dataset contains transvaginal ultrasound images and linked histopathological and clinical data, which carry a high re-identification risk even after anonymization, particularly given the imaging modality and the relatively narrow, well-defined patient population. Data processing and storage are governed by a data-sharing agreement between Semmelweis University and GE HealthCare Hungary Ltd., under which anonymized data are accessible only to authorized GE HealthCare personnel on a secure, access-restricted, encrypted server, in compliance with the EU General Data Protection Regulation (GDPR). This arrangement does not extend to third-party researchers outside the collaboration.
