MRI detected extramural vascular invasion (mrEMVI) is potential imaging predictive biomarker for selecting optimum treatment method and is closely correlated with poor prognosis. Several studies have been done to understand the correlation between EMVI and metastasis, but not synchronous metastasis to be specific. We aimed to analyze the correlation between clinical factors including mrEMVI with synchronous metastasis. Moreover, we analyzed the correlation between grades of mrEMVI and synchronous metastasis.
