摘　　要：目的探讨CT、"C"臂双相导引经皮穿刺腰椎间盘造影(CTD)的技术。方法对IDET治疗腰椎间盘突/膨出患者中的45例进行CT、"C"臂导引下腰椎间盘造影。其中5例做单层面的造影,40例做两个椎间盘层面,共85个椎间盘层面。85个椎间盘中5个位于L3~4、43个位于L4~5、37个位于L5~S1。结果45例椎间盘层面CT即刻扫描,38例椎间盘层面术后2小时CT再次扫描。观察到19例造影剂聚集在髓核内,39例造影剂不同程度同心圆样从髓核溢出,到达纤维环内、中、外层,27例见髓核内造影剂呈笔尖状,不同宽度带状穿过椎间盘后方的纤维环到达椎管内。结论在CT、"C"臂导引下经皮腰椎间盘穿刺、造影时,可观察穿刺针在椎间盘内的位置,能降低假阳性率,并在CT横断位图像上观察到造影剂在环、髓核内的分布,明确椎间盘纤维环、髓核的病理表现。Objective To discuss the operating methods of CT and "C"-arm X-ray guiding diphase percutaneous puncture lumbar diskography(CTD).Methods There were 49 patients with lumbar disc protrusion or bulge aclepted percutaneous intradiscal electrothermal therapy(IDET),of them 45 patients had been given a preoperative CTD.Five cases single decks and 40 cases two dects opacification were done,85 discus intervertebralis ducts in all.About 85 disci intervertebrales,5 were L_3-4,43 were L_4-5 and 37 were L_5-S_1.Results ...
