Endometriosis
Conditions
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.

Exclusion criteria
* Patients who had surgery for endometriosis prior to the surgery included in this study * Patients deemed inappropriate by the principal investigator * Patients who obtained their voluntary consent but later withdrew their consent
