摘　　要：目的探讨多层螺旋CT血管成像(MSCTA)对头颈部各种血管变异的诊断价值。方法回顾性分析229例头颈部血管的CTA成像资料,采用最大密度投影(Maximum intensity projection,MIP),容积再现技术(volume rendering,VR)多平面重组(multiplanar reconstruction,MPR)和曲面重建(curved planer reformation,CPR)对所采集的头颈血管源图像进行影像重建。由有经验的诊断医师对所得到的图像进行评估和分析,得出一致的诊断结果。结果 229例头颈部CTA共诊断胚胎型大脑后动脉(FTP)56例,开窗类变异11例,发育不良类变异25例,动脉血管重复或缺如类变异22例和其他变异18例。结论多层螺旋CTA可较好显示头颈部血管的正常解剖结构和各种血管病变、解剖变异,具有良好的定位、定量及定性能力。可作为头颈部血管变异检查的首选方法。To assess the value of multiple slice spiral CT angiography（MSCTA） in the diagnosis of variation in the cranio-cervical arteries. Methods 229 patients of cranio-cervical CT angiography（CTA） had been performed by 64-slice spiral CT. The data of 229 patients were reconstructed with maximum intensity projection（MIP）, volume rendering（VR）, multiplanar reconstruction（MPR） and curve planar reconstruction（CPR）. All images obtained were analyzed retrospectively by two experienced radiologists and the result of diagnosis were consistent. Results 132 patients with variations of the cranio-cervical arteries were identified, including Ietal origin of the posterior cerebral artery FTP（n=56）, arterial fenestration（n=l 1）, arterial dysplasia（n=25） and variations of arterial repeat or absent（n=22）. Canclusions Normal anatomic structure, various vascular lesions and variation of cranio-cervical arteries could be well demonstrated by multiple slice spiral CT angiography. MSCTA has good location, quantitative and qualitative ability and is suggested to be the first choice in the examination of cranio-cervical arteries.
