MRI-detected extramural vascular invasion is an independent prognostic factor for synchronous metastasis in patients with rectal cancer.

摘要

? EMVI, LN metastasis and T staging on MRI are risk factors for metastasis. ? EMVI in large vessels has greater risk for metastasis than in small vessels. ? Regional LN metastasis on MRI has highest risk for predicting metastasis. ? MR findings could be helpful for selecting patients at high risk for metastasis.
