| 摘 要： | 目的利用16排螺旋CT双期增强扫描对胃癌进行T分期并与病理对照,确定多排螺旋CT(multi-detec-tor row CT,MDCT)在术前T分期中的作用。资料与方法经胃镜证实的62例患者(63个病灶),术前采用16排螺旋CT平扫和动脉期、门静脉期双期增强扫描,随后根据5 mm层厚横断面图像情况重组薄层动脉期和门静脉期多平面重组(multiplanar reconstruction,MPR)图像,由两名资深放射科医师共同完成T分期,术后与病理对照。结果 MDCT结合MPR技术后对胃癌的检出率为96.7%,其中对早期胃癌的检出率为66.7%,进展期胃癌的检出率为100%。胃癌的MDCT大体分型准确率为88.9%。63个胃癌MDCT术前T分期总体准确率为71.4%,其中早期胃癌准确率为33.3%,进展期胃癌准确率为75.4%。结论采用MPR后处理技术的MDCT配合动态增强扫描对进展期胃癌的检出、大体分型和T分期准确率明显提高。
