目的：探讨64排螺旋CT在糖尿病足下肢血管病变诊断中的应用价值。方法对48例糖尿病足患者行下肢动脉 CT血管造影（CTA ）检查，采用 CT多种后处理技术并结合原始图像进行综合比较。结果48例患者均成功获得CTA图像，其中有41例存在下肢动脉病变；40例为双侧，39例为双侧或单侧均有严重狭窄或闭塞；25例存在明显的侧支循环。下肢动脉各个节段CTA与DSA比较两者结果一致性较好（Kappa值＝0．887），阳性预测值92．5％，阴性预测值98．6％。延迟扫描后，CTA对足动脉血管支数显影增多，结果与DSA检查一致。结论 CTA能准确评估糖尿病足下肢动脉病变，可作为该病变首选检查方法。

Objective To investigate the value of vascular disease of lower extremity of 64 slice spiral CT angiography in patients with diabetic foot.Methods 48 patients with diabetic lower limb underwent arterial CT angi-ography,Using CT a variety of post -processing techniques and compared with the original image.Results 48 patients were successfully obtained CTA image,41 patients had peripheral artery disease,40 cases were bilateral,39 cases of unilateral or bilateral had severe stenosis or occlusion;25 cases had obvious collateral circulation.Lower extremity arterial segments CTA and DSA showed good agreement (Kappa Value =0.887).Positive predictive rate was 92.5%,the negative predictive value was 98.6%.After delayed scanning,CTA on the foot artery count develo-ping increased,checked with the DSA consistency.Conclusion 64 slice spiral CTA can accurately and comprehen-sive assessment of lower extremity arterial disease of diabetic foot.Diabetic lower limb vascular lesions can be used as the preferred method of examination.
