简要总结
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.

结局指标
主要结局
At least one measurable parameter (yes/no) on tractography in patients with or without endometriosis.
时间窗: 3 months
Evaluate the ability of the diffusion tensor sequence to visualize normal or pathological pelvic nerve plexuses (hypogastric and sciatic) in pelvic endometriosis. These parameters will be measured on MRI tractography images.
Proportion of patients with at least one relevant parameter evaluated by MRI-based tractography, in patients with or without endometriosis
时间窗: Between 7 and 60 days after inclusion
Number of patients (with or without endometriosis) in whom at least one parameter could be evaluated, divided by the total number of patients (with or without endometriosis) who attended an MRI-based tractography. Parameters expected to be evaluable with MRI-based tractography: * total volume * lengths * number of branches * tortuosity MRI will be exploited by independant readers, blinded from patients'clinical characteristics and diagnosis
