摘要
目的探讨闭孔神经16层螺旋 CT 多平面重建同层显示的影像学特点及临床价值。方法选取60例闭孔神经正常成人志愿者,31例闭孔神经病变者。使用美国 GE 公司制造的 Lightspeed 16层螺旋 CT 对腰椎进行扫描,在工作站 ADW4.1,利用 UNIX 系统 DICOM 格式对闭孔神经进行多平面重建,取其同层显示层面,观察其影像学解剖特点并分析其病变者的主要异常表现。结果16层螺旋 CT 在斜冠状面及斜矢状外旋切面可同层显示闭孔神经起点至骨盆闭孔处的整体形态、粗细、走行方向、长度、毗邻关系及张力状态;而病变者同样可理想地显示其异常的基本表现。结论16层螺旋 CT 多平面重建可理想地同层显示闭孔神经的起点至骨盆闭孔处的解剖学特点及疾病下的基本表现。它对临床闭孔神经有关疾病的诊断及治疗具有极重要的应用价值。
Objective To explore the features of obturator nerve （ON） by high-resolution CT （HRCT） at the same slice with multiplanar planer reconstruction techniques and clinic value thereof. Methods The normal lumbar vertebral bodies of 60 healthy adults and the abnormal lumbar vertebral bodies of 31 patients with ON disorders were scanned with 16-slice spiral CT, multiplanar reconstruction was conducted in the Workstation ADW4.1, with UNIX system and DICOM form. The images at the same slice were studied. Results The shapes, thickness, direction, length, adjourning relationship, and tension could be shown at the same slice of oblique and coronal section or oblique and sagittal plane with rotation in external sides on the way from the starting point of dural sac to foramen obturatum in pelvis, meanwhile the manifestations of abnormal ON also could be shown. Condusion The anatomical features and abnormal manifestation of ON at the same slice with 16-slice spiral CT using the multiplanar reconstruction techniques can be fully shown from the starting point of dural sac to the foramen obturatum in pelvis . This technique is very important in diagnosis and treatment of diseases of obturator nerve.
