摘　　要：目的分析CT血管造影(CTA)在2型糖尿病(T2DM)患者下肢血管病变(LEAD)诊断及病情程度评估中的应用价值。方法选取124例(合计1510段血管)T2DM并LEAD患者的临床资料进行回顾性分析,患者均经过CTA、磁共振血管造影(MRA)及血管数字减影(DSA)检查,以DSA诊断及病情程度检查结果作为金标准,分别对CTA、MRA检查做一致性检验,对比两种检查方式的准确性。结果诊断结果一致性检验显示,CTA检查灵敏度(98.18%)、特异度(98.98%)、准确度(98.54%)与MRA检查结果差异无统计学意义(P>0.05);检查狭窄程度>50%的结果与金标准的一致性检验结果显示,CTA检查灵敏度(94.59%)、特异度(98.32%)、准确度(96.95%)均明显高于MRA检查(91.35%、96.44%、94.57%)(P<0.05);检查狭窄程度>75%结果与金标准的一致性检验结果显示,CTA检查特异度(98.69%)、准确度(97.22%)均明显高于MRA检查(97.20%、95.63%)(P<0.05),但两种检查方式灵敏度(92.62%,90.71%)比较差异无统计学意义(P>0.05)。结论MRA与CTA诊断LEAD的效能相当,CTA评估LEAD患者病情方面优于MRA,但两种检查方式相较于金标准,均有着较高的准确性。Objective To analyze the application value of CT angiography(CTA)in the diagnosis and evaluation of lower extremity arterial disease(LEAD)in patients with type 2 diabetes mellitus(T2DM).Methods The clinical data of 124 patients(1510 segments of blood vessels)with T2DM and LEAD were retrospectively analyzed.All patients underwent CTA,MRA and DSA,and DSA diagnosis and disease severity examination results were used as the gold standard.The consistency test of CTA and MRA was performed to compare the accuracy of the two methods.Results The consistency test showed that the sensitivity(98.18%),specificity(98.98%)and accuracy(98.54%)of CTA were not significantly different from those of MRA(96.97%,98.83%,97.81%)(P>0.05).The consistency test results between the results of detecting stenosis>50%and the gold standard showed that the sensitivity(94.59%),specificity(98.32%)and accuracy(96.95%)of CTA were significantly higher than those of MRA(91.35%,96.44%,94.57%)(P<0.05).The consistency test results between the results of detecting stenosis>75%and the gold standard showed that the specificity(98.69%)and accuracy(97.22%)of CTA were significantly higher than those of MRA(97.20%,95.63%)(P<0.05).However,there was no significant difference in sensitivity(92.62%,90.71%)between the two methods(P>0.05).Conclusion The efficacy of MRA and CTA in diagnosing LEAD is comparable,and CTA is better than MRA in evaluating the condition of LEAD patients.However,compared with the gold standard,both methods have higher accuracy.
