磁共振成像盆底三维重建的方法及意义

磁共振成像(MRI)盆底三维重建可以了解盆底解剖,协助盆底缺陷诊断。目前,MRI盆底三维重建的内容包括骨盆、盆腔器官、盆底肌肉、韧带等,是研究盆底的最新方法。笔者对年轻未育、足月单胎妊娠晚期、广泛性全子宫切除术后、盆腔器官脱垂(pelvic organ prolapse,POP)患者的盆底研究发现,通过运用该方法可以直观观察不同状态的女性盆底、了解盆底的解剖状况并反映功能异常,可协助诊断盆底功能障碍性疾病,是较超声更为直观先进的方法。但盆底三维重建技术基于较为昂贵的MRI检查数据,且该技术的掌握相对困难,因而适合科学研究,临床推广有一定难度。

Method and significance of 3D reconstruction of pelvic floor based on MRI.

The 3D reconstruction of pelvic floor based on MRI can help to understand pelvic floor anatomy and assist the diagnosis of pelvic floor defect.At present，the 3D reconstruction of pelvic floor based on MRI include pelvis，pelvic organs，pelvic floor muscles，ligaments and so on，which is the latest method of studying pelvic floor.The author has researched the pelvic floor of young nullipara，the women at full-term late pregnancy or with radical hysterectomy and POP patients，and found that with this method the pelvic floor can be observed in different states，which helps to understand the anatomy and function of pelvic floor abnormalities，assist the diagnosis of pelvic floor dysfuctions，which is more advanced than pelvic ultrasound.But the three-dimensional reconstruction of pelvic floor is based on MRI examination，which is more expensive，and the technology is relatively difficult to grasp，so it is suitable for scientific research，but has some difficulties in clinical promotion.
