摘　　要：直肠癌是一种我国乃至全球发病率较高的恶性肿瘤。近年来,常规MRI及功能MRI在直肠癌的应用方面发展迅速。本文汇总高分辨率MRI、动态对比增强MRI、扩散加权成像、体素内不相干运动MRI在评估直肠癌术前分期、放化疗后再分期、放化疗疗效方面的国内外文献,希望将各模态MRI的优劣势整合,为临床的诊治提供更加可靠的影像学依据。Rectal cancer(RC)is a malignant tumor with high incidence in China and even in the world.In recent years,the application of conventional MRI and functional MRI in RC has developed rapidly.This paper summarized domestic and foreign literatures on high-resolution MRI,dynamic contrast enhanced MRI,diffuse-weighted imaging,intravoxel incoherent motion MRI in evaluating the preoperative staging,restaging after chemoradiation,and the efficacy of chemoradiation in RC,hoping to integrate the advantages and disadvantages of each mode of MRI and provide more reliable imaging basis for clinical diagnosis and treatment.
