目的：64排CT血管造影(CTA)低剂量扫描在颈动脉狭窄诊断中的应用价值。方法回顾性分析头颈部64排CTA低剂量扫描检查的拟诊为缺血性卒中的30例患者的临床资料,患者入院7 d内先后行CTA与数字减影血管造影(DSA)检查,评价64排CTA低剂量扫描对颈动脉狭窄诊断的灵敏度、特异度。结果30例患者行64排CTA低剂量扫描和DSA检查共得到60支颈动脉图像结果。CTA诊断正常20支,狭窄40支,中度及以上狭窄共22支,占55.0%。DSA诊断正常21支,狭窄39支,中度及以上狭窄19支,占48.7%。CTA对中度及以上狭窄程度诊断评价与DSA检查结果比较其灵敏度、特异度为86.4%、87.5%。结论64排CTA在颈动脉狭窄程度分级的判定中与DSA有较高的一致性,64排CTA低剂量扫描可以作为颈动脉狭窄的筛查手段之一,可最大限度地避免辐射效应可能产生的不良后果。

Objective To investigate the application value of 64-slice spiral CT angiography (CTA) low-dose scan in diagnosis of carotid artery stenosis. Methods Clinical data of 30 diagnosed ischemic stroke patients by head and neck 64-slice spiral CT low-dose scan were retrospectively analyzed. CTA and digital subtraction angiography (DSA) were applied for patients within 7 d after admission. Evaluation was made on sensitivity and specificity of 64-slice spiral CT low-dose scan in diagnosis of carotid artery stenosis. Results 64-slice spiral CT low-dose scan and DSA examination were applied in 30 patients for 60 carotid artery images. There were 22 normal cases, 40 stenosis cases, 22 cases with moderate and severe stenosis, accounting for 55.0%by CTA. In DSA diagnosis, there were 21 normal cases, 39 stenosis cases, 19 cases with moderate and severe stenosis, accounting for 48.7%. Sensitivity and specificity of CTA diagnosis of moderate and severe stenosis and DSA examination results were 86.4%and 87.5%. Conclusion 64-slice spiral CT has high consistency with DSA in diagnosis of carotid artery stenosis. 64-slice spiral CT low-dose scan can be used as one of the screening methods of carotid artery stenosis, and it can furthest avoid adverse reactions of irradiation effect.
