| 摘 要： | 目的:评价64排螺旋CT血管造影在下肢动脉闭塞性及狭窄性病变中应用价值。方法:采用美国GE公司生产LightSpeedVCT对52例患者进行下肢血管造影检查。扫描层厚0.625 mm,管电压120 KV、管电流130-205 mAs,扫描时间约为10秒。图像后处理技术多采用VR、MIP、MPR、cMPR,图像分析密切结合原始轴位图像。结果:67支血管未见明确病变,CTA显示狭窄血管共77支,5支血管闭塞;狭窄≥50%,≤75%共21支;狭窄≤50%共51支。结论:64排CTA图像在发现闭塞远端血管方面优于DSA,可以清晰显示闭塞远端侧枝供血血管。随着64排螺旋CT临床广泛应用,在下肢血管疾病诊断方面的优势会得到长足发展。
