| 目的：探讨低剂量CT 扫描在下肢动脉脉阻塞性病变诊断中的应用价值。方法：选择127 段经DSA 确诊的不同部位下肢动
脉阻塞性病变行低剂量CT 扫描，并采用MPR,VR,MIP 等重建方法获得各下肢动脉CTA 图像，将CTA 图像与DSA 图像的诊断
结果利用统计学软件SAS8.1 行加权Kappa 一致性检验，检验水准为：Kaapa.系数大于0.75。结果：所得CTA 图像与DSA 图像诊
断结果的一致性检验的kappa 系数为0.8058，两种诊断结果的一致性为优。结论：采用低剂量扫描条件获得高质量的CTA 图像在
下肢动脉阻塞性病变的诊断上有肯定的价值。 |

| Objective: To investigate the application value of low-dose CT scanning in lower extremity arterial occlusive disease.
Methods: Select 127 segments different parts of lower extremity arterial occlusive disease confirmed by DSA in low dose CT scan, By
MPR, VR, MIP reconstruction methods to obtain images of the lower limb CTA, The CTA and DSA image diagnosis using statistical
software SAS8.1 consistency test by weighted Kappa, Inspection standards: Kappa coefficient greater than 0.75. Results: CTA and DSA
images for the diagnosis obtained the consistency test kappa coefficient 0.8058, the consistency of the two excellent diagnostic results.
Conclusion: Low-dose CTA scanning conditions to obtain high quality images in lower extremity arterial occlusive lesions have positive
value. |
