| 摘 要： | 目的：对比分析16层螺旋CT中腰椎间盘轴位扫描与容积扫描后通过工作站多平面重组（MPR）的优劣。方法：随机抽取16层螺旋CT中的腰椎间盘轴位扫描与容积扫描后经MPR完成的受检者各50例,将其分为A、B两组。分别从图像的质量、辐射剂量、扫描时间三方面,对两种扫描方法做出对比分析。结果：除外脊柱侧弯、腰骶角大于机架最大倾角等因素,两种方法所获腰椎间盘图像,均完全满足腰椎间盘病变的诊断要求,图像质量无明显差异;辐射剂量就同样个数的腰椎间盘来讲,轴位扫描法明显少于容积扫描法,其剂量不到容积扫描法的1/2;完成整个扫描过程所用时间,两种扫描方法无明显差异。结论：对椎间盘的CT检查,最好采用轴位扫描法,以减少病人所受的辐射剂量。

| Abstract: | Objective: To have a contrastive study of the advantages and disadvantages of the axial scanning and volume scanning after multi-planar reconstruction(MPR) at the workstation for the lumbar discs with 16-slice spiral CT.Methods: Randomly select cases by the axial scanning(Group A) and the volume scanning after multi-planar reconstruction(Group B) with 16-slice spiral CT and each group contains 50 cases.Analyzing contrastively on the quality of the images,radiation dose,scanning time of the two scanning mode... |
