Abstract:

【】 目的 利用首过时间技术进行全胰腺CT灌注扫描,了解正常胰腺CT灌注的特点。 方法 2006年6月-2007年3月,64例正常胰腺患者行64排螺旋CT灌注扫描,测量胰头、胰体及胰尾的灌注值、强化峰值、达峰时间和血容量。分别按患者的性别、年龄及胰腺测量的部位分组,将灌注参数进行统计分析。 结果 ①男性胰腺的血容量高于女性(P0.05)。②41~60岁组的灌注值低于60岁组;>60岁组的强化峰值高于41~60岁组;41~60岁组的达峰时间长于60岁组的血容量高于41~60岁组(P60(P60wassignificantlyhigherthanthatintheagegroupof41-60(P60wassignificantlyhigherthanthatintheagegroupof41-60(P<0.05).③Theperfusionvaluesofthebodyandthetailweresignificantlyhigherthanthatofthehead(P<0.05). Conclusion Therearesignificantdifferencesintheperfusionparametersbetweendifferentsexesandamongseveralagegroupsandsites.Thefirst-passtechniqueofperfusionappliedinnormalpancreascanreflectthesefeatures.
