Abstract:

目的?通过和CT胰腺体积测量比较,探索三维超声测量胰腺体积的可行性和准确性。方法?2010年1月-2011年5月按照纳入和排除标准纳入40岁以上成人40例,分别使用三维超声和增强对比CT进行全胰腺扫描,使用相应软件测量胰腺体积。结果?三维超声测得的胰腺体积(45.70±11.19)cm3明显较CT测量值(47.23±11.23)cm3低,两者比较差异有统计学意义(P<0.05)。三维超声与CT测量值呈正相关关系(组内相关系数=0.988,P<0.05);两种测量方法的平均误差为(?3.41±2.72)%,其95%的一致性限度为(?8.74%,1.92%)。结论?三维超声是测量胰腺体积的一种有效工具,可在一定程度上替代CT测量。
