多层螺旋CT血管成像在出血型烟雾病诊断中的准确性

Accuracy of Multi-slice Spiral CT Angiography in Diagnosing Hemorrhagic Moyamoya Disease

目的通过与DSA对比,评价多层螺旋CT血管成像(MSCTA)在出血型烟雾病(MMD)诊断中的准确性。方法 523例临床怀疑有出血型MMD的患者全部行MSCT检查,其评价结果与DSA进行回顾性对比研究。结果根据DSA检查结果,在523例患者中的37例是MMD患者,MSCTA明确诊断了所有的MMD患者。MSCTA均清晰显示了颈内动脉、大脑前动脉及大脑中动脉狭窄和闭塞,双侧病变者31例(84%),单侧病变者6例(16%)。结论 MSCTA对于MMD检出具有很高的准确性,可以作为出血型MMD诊断的首选影像检查。

Objective To assess the diagnostic accuracy of multi-slice spiral CT angiogra- phy （MSCTA） in detecting hemorrhagic moyamoya disease （MMD） compared with digital subtraction angiography （DSA）. Methods 523 cases with snspected hemorrhagic MMD received MSCT scan, and the results were compared to DSA retrospectively. Results According to DSA, 37 of 523 cases were MMD patients, and MSCTA detected all MMD cases. MSCTA clearly showed stenosis and obstruction of internal carotid artery, anterior cerebral artery and middle cerebral artery, including 31 cases （84%） with bilateral and 6 cases （16%） with single lateral. Conclusion MSCTA is a highly accurate imaging examina- tion of the first choice for diagnosing hemorrhagic MMD.
