| 目的 探讨64层螺旋CT血管造影(64-SCTA)诊断短暂性脑缺血发作(TIA)病因的价值。方法 选择临床拟诊为TIA患者40例进行头颈联合64-SCTA和数字减影血管造影(DSA)检查,观察头颈部血管病变显示情况。以DSA为金标准,计算64-SCTA检出病变的敏感度、特异度和准确率,并比较64-SCTA与DSA对血管狭窄程度的评价结果。结果 40例TIA患者有440支血管得到评价,64-SCTA对TIA患者头颈血管病变检出的敏感度、特异度及准确率分别为94.12%、98.52%和98.19%,64-SCTA及DSA对病变的检出率差异无统计学意义(χ2=0.066,P=0.798);64-SCTA目测法对血管狭窄率的评估与DSA具有较高的符合率(31/32,96.88%)。结论 头颈联合64-SCTA对TIA患者头颈血管病变的检出具有较高的敏感度、特异度和准确率,对TIA的病因诊断具有重要临床价值。 |

| Objective To explore the value of 64-slice CT angiography (64-SCTA) in etiological diagnosis of transient ischemic attack (TIA). Methods Forty patients with clinically primary diagnosed TIA underwent 64-SCTA and digital subtraction angiography (DSA), and the lesions of intracranial and cervical arteries were displayed. Taking DSA as gold standard, the sensitivity, specificity and accuracy rate of 64-SCTA were calculated respectively, and the degree of angiostenosis was evaluated with 64-SCTA. Results A total of 440 blood vessels were evaluated in 40 patients. The sensitivity, specificity and accuracy rate of 64-SCTA was 94.12%, 98.52% and 98.19%, respectively. The difference of detection rate between 64-SCTA and DSA had no statistical difference (χ2=0.066,P=0.798); the conclusion of ocular estimate with 64-SCTA had higher coincidence (31/32,96.88%) with that of DSA. Conclusion Being valuable in etiological diagnosis of TIA, 64-SCTA has high sensitivity, specificity and accuracy rate. |
