目的 探讨多层螺旋CT血管造影(MS-CTA)容积重建(VR)技术在Moyamoya病中的诊断价值.方法 对经DSA证实的25例Moyamoya患者的MS-CTA影像资料进行回顾性分析,使用GE Lightspeed pro 16层螺旋CT扫描仪获得原始图像,所有病例均采用VR技术对图像进行三维重建.结果 25例CT平扫患者中,脑梗死13例,脑出血12例,其中11例可见丘脑一基底节区有扩张的血管;MS-CTA VR重建显示Moyamoya病颈内动脉(ICA)末端、大脑中动脉(MCA)或大脑前动脉(ACA)近端闭塞或狭窄的准确率为88.0%(22/25).与DSA相比,MS-CTA VR重建高估动脉狭窄程度,将ICA狭窄误诊为闭塞3例(12.0%);在显示Moyamoya血管数目及分支方面,MS-CTA VR重建显示细小分支数目较少;在显示侧支循环方面,MS-CTA VR重建仅显示6例(25.0%).结论 CT平扫仍是发现Moyamoya病继发病变的常规方法,与MS-CTA VR重建相结合可正确诊断Moyamoya病.
目的 探討多層螺鏇CT血管造影(MS-CTA)容積重建(VR)技術在Moyamoya病中的診斷價值.方法 對經DSA證實的25例Moyamoya患者的MS-CTA影像資料進行迴顧性分析,使用GE Lightspeed pro 16層螺鏇CT掃描儀穫得原始圖像,所有病例均採用VR技術對圖像進行三維重建.結果 25例CT平掃患者中,腦梗死13例,腦齣血12例,其中11例可見丘腦一基底節區有擴張的血管;MS-CTA VR重建顯示Moyamoya病頸內動脈(ICA)末耑、大腦中動脈(MCA)或大腦前動脈(ACA)近耑閉塞或狹窄的準確率為88.0%(22/25).與DSA相比,MS-CTA VR重建高估動脈狹窄程度,將ICA狹窄誤診為閉塞3例(12.0%);在顯示Moyamoya血管數目及分支方麵,MS-CTA VR重建顯示細小分支數目較少;在顯示側支循環方麵,MS-CTA VR重建僅顯示6例(25.0%).結論 CT平掃仍是髮現Moyamoya病繼髮病變的常規方法,與MS-CTA VR重建相結閤可正確診斷Moyamoya病.

Objective To evaluate the diagnostic value of multi-slice thrce-dimensional computed tomographic angiography(MS-CTA) with volume rendering(VR) for Moyamoya disease.Methods MS-CTA of 25 patients with Moyamoya disease verified by DSA were restrospectively analyzed.Source images were got by GE Lightspeed pro scanner.VR was adopted to reconstruct 3D images in all cases.Results Of 25 CT precontrast,13,12 cases showed infarction and hemorrhage respectively,while 11 cases had dialated vessels in thalamus-basal ganglia region on CT.Accuracy of stenosis or occlusion of the bifurcation of ICA, proximal portion of the ACA or MCA was 88.0% (22/25) by MS-CTA.MS-CTA overestimated the degree of stenosis,MS-CTA misdiagnosed 3 cases(12.0%)with stenosis to occlusion.MS-CTA showed fewer small Moyamoya vessels than DSA.MS-CTA only demonstrated 6 cases(25.0%)with collateral vessels.Conclusion CT is still the conventional method for detecting secondary lesions to Moyamoya disease.CT and MS-CTA can accurately diagnose Moyamoya disease.
