Rectal cancer is a malignant tumor with extremely high morbidity and mortality. It will change the physical microenvironments, but it is still a challenge to differentiate the rectal cancer with and without vascular invasion. T2 mapping imaging is a quantitative biomarker with good repeatability and stability. T2 mapping can non-invasively visualize and quantify tissue components (such as edema, fibrosis etc )without contrast agent. This study aims to assess the performance of T2 mapping on differentiating rectal cancer with and without vascular invasion, which may yield higher diagnostic confidence.
