Middle compartment defects, a common subtype of pelvic floor dysfunction (PFD), are primarily characterized by the prolapse of the uterus or vaginal vault. Magnetic resonance imaging (MRI) has emerged as a valuable diagnostic tool for PFD, offering superior soft tissue resolution while eliminating exposure to ionizing radiation. This review comprehensive summarizes current applications of MRI in the diagnosis and treatment of PFD, covering measurement methods, manifestations of three-level structural defects, postoperative efficacy evaluation, vaginal axial assessment, and evaluation of the mesh status. The authors suggest that MRI enables precise preoperative evaluation of three-level defects, thereby facilitating the development of personalized treatment plans. Additionally, MRI provides an accurate postoperative assessment of surgical outcomes and mesh status, offering a new basis for postoperative assessment. MRI demonstrates unique value in the diagnosis and treatment of middle compartment defects.
中盆腔缺陷是盆底功能障碍（PFD）的一种常见亚型，主要特征为子宫或阴道穹窿脱垂。磁共振成像（MRI）已成为PFD的一种有价值的诊断工具，它提供了卓越的软组织分辨率，同时避免了电离辐射暴露。本综述全面总结了MRI在PFD诊断和治疗中的当前应用，涵盖测量方法、三级结构缺陷的表现、术后疗效评估、阴道轴向评估以及网片状态评估。作者认为，MRI能够对三级缺陷进行精确的术前评估，从而有助于制定个性化的治疗方案。此外，MRI为手术结果和网片状态提供准确的术后评估，为术后评估提供了新的依据。MRI在中盆腔缺陷的诊断和治疗中显示出独特的价值。
