Abstract Objective: To evaluate the value of 3.0T high resolution MRI in preoperative T staging of rectal cancer. Methods: Ninety-five cases of rectal cancer were taken into the study. All of them had a rectum MRI before surgery. The results of MRI for T staging were compared with that of histopathology. Result: The accuracy rate was 89.5% for T staging in total, 90.5% for T1~T2, 89.5% for T3, 98.9% for T4. A statistic analysis indicated that preoperative MRI for T staging was better consistent with pathologic T staging(Kappa=0.764, P=0.000). Conclusion: Preoperative 3.0T high resolution MRI may make an exact T staging.
