Abstract
Objective: To identify the accuracy in staging diagnosis of magnetic resonance imaging (MRI) in rectal cancer compared to pathological results. Subject and method: The cross-sectional study was conducted with convenient sampling on 109 patients diagnosed with rectal cancer who underwent radical resection at the Department of Colorectal and Perineal surgery, VietDuc University Hospital from October 2016 to May 2019. Result: MRI had a significant correlation with pathological results in terms of T stage (p<0.001). The assessment of MRI in early stage (T1) was limited, the accuracy in determining invasion was 71.56%. No correlation was found in the diagnosis of lymph node metastasis between MRI and pathological results. The ability of evaluating circumferential resection margin (CRM), vascular, lymphatic, and neurological invasion (EMVI) was decent. Conclusion: MRI is an important tool in assessing the invasion of the tumor as well as CRM, EMVI. It should be applied widely in the preoperative assessment of rectal cancer
