About

This research focuses on evaluating the ability of diffusion tensor imaging (DTI) to detect nerve damage in pelvic endometriosis. The primary objective is to visualize pelvic nerve plexuses to better understand the mechanisms of endometriosis-related neuropathic pain. Secondary objectives include comparing nerve damage between women with and without endometriosis.

To answer this question, it is planned to include 110 women with symptoms compatible with endometriosis, in Paris hospitals (Hôpital Cochin and HEGP). This research is funded by Assistance Publique - Hôpitaux de Paris. The expected duration of the research is 2 years, with individual participation of 3 months.

The research process will be as follows:

• Visit 0 (V0): Initial consultation to assess your state of health, complete pain questionnaires (EHP5, EHP30, DN4, EVA), and obtain your informed consent. Prescription of MRI.
• Visit 1 (V1): MRI with diffusion tensor imaging (DTI) within 60 days of V0. The MRI examination will be 10 minutes longer than the usual MRI. An intramuscular injection of glucagon hydrochloride will be given as part of the treatment.
• Visit 2 (V2): Follow-up consultation at 3 months, where the results of the standard MRI sequences will be discussed.

Research constraints and modalities:

• The addition of the DTI sequence extends the routine MRI by 10 minutes.
• You must attend each scheduled appointment. If you are unable to attend, please inform your doctor.
• No additional medications, treatments or samples are required for this study. You will be expected to follow your usual endometriosis treatments, with no specific restrictions on the drugs used, but please report any use of alternative medicine to your doctor.

No additional hospitalization is planned.

Patients with symptoms compatible with possible endometriosis

Experimental group

Description:

Patients will have an initial gynecological surgery consultation to determine the indication for MRI to diagnose and/or assess pelvic endometriosis. MRI will be performed at the HEGP, comprising a T2-weighted isotropic thin-section (3D) cube sequence (1 mm3), and a T1-weighted isotropic 3D DIXON sequence (1 mm3), for a total duration of 20 minutes (including set-up). Patients will also have a pelvic ultrasound if they have not already had one at a center specializing in endometriosis. They will have a further consultation after the MRI, so that the gynecological surgeon can discuss therapeutic management. All these procedures are performed as part of routine management.

Other: MRI
