Keyword:  椎基底动脉延长扩张症CT灌注成像时间-密度曲线;
Abstract: 目的:应用多排螺旋CT灌注成像对椎基底动脉延长扩张症(VBD)患者及正常基底动脉的时间-密度曲线(TDC)进行定量分析,研究两者间的差异.方法:对14例VBD患者及22例正常志愿者进行头颅CT灌注检查,绘制基底动脉TDC图并对各参数进行量化及对照分析.结果:VBD组的达峰时间与对照组对比差异有统计学意义(P<0.05),VBD组比对照组达峰时间延长.VBD组的峰值及斜率与对照组对比差异无统计学意义(P>0.05).VBD组基底动脉直径与斜率呈正相关(P< 0.05),与达峰时间及峰值无明显相关性(P>0.05).结论:通过VBD患者TDC的定量分析研究,能了解VBD患者基底动脉的血流动力学情况.
