This article provides an overview of MRI as a dynamic imaging modality as well as recent updates on the role of MRI in the evaluation of female pelvic floor disorders, including pelvic organ prolapse (POP), rectal prolapse, and defecatory dysfunction.
Pelvic floor disorders in women are common, and demand for treatment is high. Recently, multidisciplinary guidelines for dynamic MRI have been published to reflect this need. Despite criticisms that MRI is an expensive modality, cost-analysis studies are demonstrating utility for MRI in surgical decision-making trees for patients at risk for treatment failure after POP repairs. Novel measures such as anterior pelvic area and levator volumes are being used to predict and study patients with and at risk for POP. Recent standardized radiographic guidelines as reviewed in this paper will likely lead to improved reproducibility of dynamic MRI techniques across institutions, making complex pelvic floor assessment increasingly accessible to patients while creating opportunities for novel and collaborative research.
本文概述了 MRI 作为一种动态成像方式，以及 MRI 在女性盆底疾病评估中的最新作用，包括盆腔器官脱垂（POP）、直肠脱垂和排便功能障碍。
女性盆底疾病很常见，治疗需求很高。最近，已经发布了多学科动态 MRI 指南，以反映这一需求。尽管有人批评 MRI 是一种昂贵的方式，但成本分析研究表明，对于有 POP 修复后治疗失败风险的患者，MRI 对手术决策树有帮助。目前正在使用新的指标，如骨盆前区和提肛肌体积，来预测和研究 POP 患者及其风险。本文回顾的最新标准化放射学指南可能会导致各机构之间动态 MRI 技术的重复性提高，使复杂的盆底评估更容易为患者所接受，同时为新的合作研究创造机会。
