宝石能谱CT三维血管成像用于椎基底动脉延长扩张综合征患者诊断中的临床效果

The Clinical Effect of Three Dimensional CT Angiography in the Diagnosis of Vertebrobasilar Artery Dilatation Syndrome

目的:分析在椎基底动脉延长扩张综合征患者诊断中应用宝石能谱CT三维血管成像的效果。方法:选择2014年12月-2016年11月在本院经脑血管检查发现为椎基底动脉延长扩张综合征的患者32例参与研究,全部患者均选择宝石能谱CT三维血管成像诊断,分析结果。结果:依据VBD影像学特点分型,14例为Ⅰ型;10例为Ⅱ型;8例为Ⅲ型(2例椎动脉延长迂曲,2例单纯椎动脉延长扩张,4例单纯基底动脉扩张)。结论:宝石能谱CT扫描速度快,宝石探测器密度分辨率更高,使得诊断更精确,并且降低了剂量,能够减少对患者的辐射损伤。

Objective： To analyze the effect of three dimensional CT angiography in the diagnosis of vertebrobasilar dilatation syndrome. Methods： From December 2014 to November 2016 in our hospital after cerebrovascular examination found 32 cases of vertebrobasilar dolichoec syndrome patients participated in the study, all patients were selected gemstone spectral CT angiography diagnosis, the results of the analysis. Results： According to the imaging characteristics of VBD type, 14 cases of type 1; 10 cases of type II; 8 cases were type III（2 cases of vertebral artery extending tortuous, 2 cases of simple vertebral artery was dilated, 4 cases of basilar artery dilatation）. Conclusion： CT can be used to scan the gem with high speed and high density resolution, which can make the diagnosis more accurate, and reduce the dose.
