| 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LightSpeed
VCT 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

| 英文摘要: |
| Objective: To evaluate the potentialities of 64-row CT angiography in arterial Occlusive and narrow venereal disease
of lower extremity. Methods: Use the American GE VCT LightSpeed to detect 52 patients of lower extremity arterials, slice thickness
0.625 mm, 120 KV, 130-205 mAs, scanning time for about 10 seconds. VR and MIP and cMPR and MPR were used in the post-processing
technology. Image analysis was closely combined with the original axial images. Results: No obvious diseases were found in 67 vessels.
CTA showed there were 77 narrow vessels, 5 vessels with occlusion, 21 vessels with stenosis among 50 % and75%, and 51 vessels
with stenosis ≤ 50%. Conclusion: CTA image excels DSA in the discovery of distal vascular occlusion. With the wide application in
clinic, 64-row CT will get full development in diagnosis of lower extremities vascular disease. |
