静、动态MRI用于盆底功能障碍肛提肌评价的研究进展

盆底功能障碍是由于盆底支持结构薄弱所引起的包括盆腔器官脱垂、排尿及排便功能障碍等一系列症状的疾病。肛提肌是支持盆底的主要结构,静态MRI具有较高的软组织分辨力,能客观地评价肛提肌的形态及结构,动态MRI能实时反映肛提肌的运动及功能,为其全面评估提供客观依据。就静、动态MRI在盆底功能障碍中对肛提肌评价的应用及研究进展予以综述。

Research progress of static and dynamic magnetic resonance imaging in evaluation of levator ani muscle for patients with pelvic floor dysfunction

Pelvic floor dysfunction including a series diseases such as pelvic organ prolapse, urinary and fecal dysfunction caused by weakness of pelvic supporting system. Levator ani muscle consists of the main component of pelvic supporting system. Static magnetic resonance imaging permits detailed assessment of anatomic structures owing to its high soft tissue resolution. Dynamic magnetic resonance imaging permits the observation of movement and functional evaluation of levator ani muscle. These provide objectively evidence for the complementary evaluation. In this article we reviewed the application and research progress of static and dynamic magnetic resonance imaging in evaluation of levator ani muscle for patients with pelvic floor dysfunction.
