Intestinal endometriosis occurs in 4% to 37% of women with deep endometriosis (DE). Noninvasive diagnosis of presence and characteristics of rectosigmoid endometriosis permits the best counseling of patients and ensures best therapeutic planning. Magnetic resonance enema (MR-e) is accurate in diagnosing DE. After colon cleansing, rectal distention and opacification improves the performance of MR-e in diagnosing rectosigmoid endometriosis. MR imaging cannot optimally assess the depth of penetration of endometriosis in the intestinal wall. There is a need for multicentric studies with a larger sample size to evaluate reproducibility of MR-e in diagnosis of rectosigmoid endometriosis for less experienced radiologists.
肠道子宫内膜异位症发生于4%至37%的深部子宫内膜异位症（DE）女性患者中。对直肠乙状结肠子宫内膜异位症的存在及特征进行无创诊断，可为患者提供最佳咨询，并确保最佳治疗方案的制定。磁共振灌肠造影（MR-e）在诊断DE方面较为准确。结肠清洁后，直肠扩张及显影可提高MR-e对直肠乙状结肠子宫内膜异位症的诊断效能。磁共振成像无法最佳地评估子宫内膜异位症在肠壁的浸润深度。需要开展多中心、大样本量研究，以评估MR-e在直肠乙状结肠子宫内膜异位症诊断中对经验较少的放射科医生的可重复性。
