An Observational Study of Patients With Endometriosis to Evaluate the Usefulness of the MEDL Score, a New Method for Evaluating Endometriosis Using MRI

Completed

• Conditions: Endometriosis

• Registration Number: NCT04846582
• Lead Sponsor: Chugai Pharmaceutical

Brief Summary

The purpose of this study is to confirm the reproducibility that the MEDL score can be evaluated by Magnetic Resonance Imaging (MRI) in the similar way as laparoscopy, the gold standard for the evaluation of the disease state of endometriosis, in order to establish the MEDL score, a new evaluation index for endometriosis using MRI. Approximately 70-90 patients with endometriosis diagnosed by imaging and who are candidates for fertility-preserving surgery will be recruited retrospectively or prospectively, and the disease status of endometriosis will be evaluated using preoperative MR images, laparoscopic surgery videos, etc. The relationship between the condition and clinical symptoms, such as pain, is also considered.
