Abstract Objective To evaluate the effect of contrast-enhanced MRI and transrectal double contrast-enhanced ultrasonography (DCEUS) in preoperative TN staging of rectal cancer.Methods Eighty-four patients with rectal cancer treated in our hospital between March 2015 and March 2018 were selected as the subjects. One week before the operation, the patients signed the informed consent form and underwent MRI and DCEUS examination. The results of examination were compared with those of histopathological evaluation while SPSS 19.0 software was used to analyze the data collected.Results The accuracy of T staging was 80.95% (68/84) for MRI and 86.9% for DCEUS(73/84). Both were well consistent (Kappa = 0.518 and 0.611 respectively) with histopathological evaluation. The accuracy of N staging with MRI was 73.81% (62/84), compared with 63.1% with DCEUS(53/84). Both had very good consistency (Kappa=0.802 and 0.694 respectively) with histopathological evaluation. There was no statistically significant difference in TN staging between them(χ²=2.12, for T staging P>0.05 and χ²=1.37 for N staging,P>0.05).Conclusions MRI is more acceptable than DCEUS,which can offer better and more effective guidance to rectal cancer surgery.
