摘要 目的:探讨多层螺旋CT(MSCT)不同图像后处理技术在十二指肠乳头检测方面的临床应用价值。资料与方法:健康志愿者30例,行MSCT检查,然后进行MPR、VR、Raysum、CTVE重建,测量十二指肠乳头大小并进行对比。结果:CTVE切线位重建图像测量十二指肠乳头直径为(0.84±0.17)cm,轴位图像测量其直径为(0.77±0.11)cm,还不能认为两者差别有统计学意义(P=0.061)。MPR、VR、Raysum、CTVE测量十二指肠乳头纵向直径分别为(1.27±0.31)cm、(1.27±0.31)cm、(1.27±0.29)cm、(0.82±0.18)cm,组间差别有统计学意义(P=0.000)。CTVE测量十二指肠乳头横、纵向直径比较,还不能认为两者差别有统计学意义(P=0.468)。结论:利用MPR、VR、Raysum、CTVE重建图像可以观察十二指肠乳头并测量其大小,但利用轴位图像和CTVE切线位重建图像测量结果较准确。
