Abstract

MRI is the first choice for preoperative evaluation of rectal cancer.It can not only provide high accuracy for T and N stage,but can also apply important factors related to the prognosis,such as extramural depth,extramural venous invasion and circumferential resection margin.Moreover,it is also promising for predicting therapeutic effects of neoaduvant chemoradiotherapy.MRI preoperative evaluation indexes and new techniques in rectal cancer were reviewed in this paper.
