摘　　要：目的探讨多层螺旋CT血管成像(multisliceCT angiography,MSCTA)对颈部动脉疾病的临床应用价值。方法对16例临床怀疑颈部动脉狭窄性病变患者行颈血管CTA检查,13例患者一侧或两侧颈动脉狭窄或闭塞,1例患者一侧椎动脉横突孔段狭窄,2例正常,其中16例患者在同期行DSA检查,以DSA结果为金标准进行效果评价。结果 16例病人基本满意地显示了两侧颈部动脉血管的正常结构和疾病分布情况。将每侧颈部动脉分为5个血管节段进行观察,16例可评价病例共观察160段血管。MSCTA显示不同程度狭窄的血管段共30段,与DSA结果比较,两者诊断总符合率为97.5%(156/160),MSCTA对颈部动脉狭窄诊断的敏感度、特异度分别为100%(28/28)、98.5%(130/132)。MSCTA与DSA二者在诊断颈动脉狭窄上有很好的一致性。结论颈部MSCTA与DSA比较,能够清晰显示颈部动脉狭窄性病变,是一种可靠的、无创的、有应用价值的检查方法。Objective To study the diagnostic value of muhi-slice spiral CTA in carotid artery diseases. Methods 16 patients suspected of carotid arterial diseases underwent multi-slice CTA. DSA was also performed on 16 patients within two weeks of the CTA. CTA was compared with DSA in these 16 patients. Results The bilateral carotid and vertebral arteries were clearly shown on all 16 patients. Of 160 segments in the carotid arteries, all segments were demonstrated in 16 patients. 30/128 stenotic arterial segments on CTA were compared with 28/128 stenotic segments on DSA. The rate of accordance was 97.5% with sensitivity and specificity of 100% （28/28） and 98.5% （130/132） respectively on CTA. Conclusion CTA can accurately display carotid artery stenosis.
