摘要 目的:探讨正常二维形态胆囊的胆囊动脉血流状态与胆囊功能之间的关系。方法:选取214例正常二维胆囊样本,用超声PW模式测得血流参数胆囊动脉平均流速(Vmean)、阻力指数(RI),用核素造影检查获得胆囊排胆分数(GBEF)。结果:将服用脂餐半小时胆囊收缩率达到50%作为正常值标准,将各例样本根据GBEF≥50%及GBEF<50%分为两组,分别为156例和58例。结果显示GBEF≥50%组Vmean高于GBEF<50%组,两组差异有统计学意义(P<0.05);GBEF≥50%组RI低于GBEF<50%组,两组差异有统计学意义(P<0.05)。结论:胆囊动脉的高阻及低Vmean状态对判断收缩功能的下降具有一定的参考价值。
