Preoperative staging diagnosis of MSCT and MRI for colorectal carcinoma

Objective To study MSCT and MRI in the preoperative staging of colorectal carcinoma and its clinical value.Methods The MSCT and MRI manifestations of 50 patients with histopathologically proven colorectal carcinoma were included,scanning results and surgical pathology results were compared,observed sensitivity by MSCT and MRI for T staging,as well as for lymph node staging accuracy.Results MRI for T1-2 staging was more sensitive than MSCT(P 0.05),MSCT and MRI on T3T4 staging sensitivity have no significant difference(P 0.05).MSCT and MRI for lymph node staging accuracy rate had no significant difference(P 0.05) by 56.59% and 58.50%,and the comparison of surgical pathological staging were not significant correlation(MSCT:P=0.288;MRI:P=0.208).Conclusion MRI on T staging accuracy of colorectal carcinoma is better than MSCT,MSCT and MRI for lymph node staging accuracy is general.
