目的:探讨较完善的腰椎退变的CT扫描技术。 材料和方法:随机抽取有临床症状行CT扫描者391例。175例行层厚,间隔各5mm,L_3～S_1区间连续扫描。7例在L_5、S_1间盘区间给15°角加扫1～2层。(连续扫描组)。216例行层厚2mm,间隔3mm,L_(3,4),L_(4,5),L_5,S_1三个间盘各自为区间的间断扫描。(各区间扫描组)。将两组数据对照,进行回顾性分析。 结果:连续扫描组椎管、脊膜囊、黄韧带、椎板的上下关节突、侧隐窝、椎弓根等解剖关系显示清楚。但
Objective: To investigate the more perfect CT scan of lumbar degeneration. Materials and Methods: A total of 391 CT scan patients with clinical symptoms were randomly selected. 175 routine thickness, 5mm intervals, continuous scanning L_3 ~ S_1 interval. 7 cases in L_5, S_1 disk interval to 15 ° angle plus 1 to 2 layers. (Continuous scanning group). Two hundred and sixty-one patients with 2 mm thickness and an interval of 3 mm were scanned intermittently for the interval of L_ (3,4), L_ (4,5), L_5 and S_1. (Each interval scanning group). Two sets of data control, a retrospective analysis. Results: The anatomy of the spinal canal, the spina bifida, the ligamentum flavum, the superior and inferior articular processes, the lateral recess and the pedicle of the vertebral plate were clearly shown in the continuous scanning group. but
