| 摘 要： | 目的：探讨16层螺旋CT对下肢动脉闭塞性疾病的诊断价值。方法：对40例临床可疑外周动脉闭塞性疾病的患者行下肢动脉16层螺旋CT血管成像,其中30例患者于CTA检查前或后两周内行DSA检查,以DSA为金标准,评价CTA诊断的准确性。结果：CTA诊断下肢动脉狭窄（≥50%）的敏感度为95.56%（129/135）,特异度为98.20%（545/555）,符合率97.68%（674/690）,阳性预测值98.88%（176/178）,阴性预测值99.61%（512/514）。结论：16层螺旋CT对诊断下肢动脉闭塞性疾病有较高的敏感性、特异性和准确性,可部分替代DSA检查。

| Abstract: | Objective:To study the value of 16-slice spiral CT angiography (MSCTA) in the diagnosis of arterial occlusive disease in lower extremities.Methods:40 patients with suspected peripheral arterial occlusive disease underwent 16-slice spiral CT angiography (MSCTA) of the arteries in lower extremities.Among them,30 patients also underwent digital subtraction angiography (DSA) two weeks before or after CTA examination.Using DSA as the gold standard,the diagnostic accuracy of CTA was evaluated.Results:Compared wit... |
