摘　　要：目的研究分析糖尿病下肢动脉疾病使用640层容积CT血管造影诊断的效果。方法 2013年2月—2015年2月我院对60例糖尿病下肢动脉疾病患者进行了640层容积CT血管造影及血管数字减影术的诊断研究,回顾患者的临床诊断资料。结果此次研究诊断使用的两种方式均是684段,以血管数字剪影当做诊断金标准来评价,640层容积CT血管造影结果显示,狭窄程度被低估和高估的均有18例,阳性预测值为99%,阴性预测值97.7%,Kappa检验K值是0.931 6。两种诊断方式的结果比较接近。结论糖尿病下肢动脉疾病使用640层容积CT血管造影诊断的准确性比较高,能够作为糖尿病下肢动脉疾病首选治疗方案。和传统的CT相比,其优势更多,准确率更高,可以将其作为传统的CT诊断替代物来使用。Objective To investigate the effect of 640 volume CT angiography in diagnosis of diabetic lower extremity arterial disease. Methods From February 2013 to February 2015, 60 patients with diabetic lower extremity arterial disease underwent 640 slice volume CT angiogmphy and digital subtraction angiography were selected and clinical data of the patients were reviewed. Results The two methods used in the study were 684, vascular digital silhouette was used as a diagnostic gold standard, 640 slice volume CT angiography showed, degree of stenosis was underestimated and overestimated in t 8 cases, the positive predictive value was 99%, the negative predictive value was 97.7%, and the Kappa test K value was 0.931 6. The results of the two diagnostic methods were relatively close. Conclusion The accuracy of the 640 volume CT anglography in diagnosing diabetic lower extremity arterial disease is relatively high. It can be used as the first choice for diabetic lower extremity arterial disease. Compared with the traditional CT, it has more advantages and higher accuracy. It can be used as a traditional CT diagnostic substitute.
