Synopsis
The results of the present study suggest that there was a significant difference in the occurrence of distant metastasis between RC patients with or without mrEMVI, CRM invasion, regional LN metastasis, and MR peritoneal reflex involvement. And mrEMVI and regional LN metastasis were independent risk factors for distant metastasis of rectal cancer. Therefore, MRI can be used to observe the status of EMVI before surgery, which is helpful for the formulation of individualized treatment plans for rectal cancer and assessment of prognosis.
