Rectal cancer with and without vascular invasion differ greatly in terms of biological behavior, treatment, and prognosis. The T2 mapping and DKI allows non-invasive evaluation of tissue composition. In this study, we investigate the performance of the combination of T2 mapping and DKI on differentiating rectal cancer with and without vascular invasion. The results indicate a better differential diagnosis is achieved by the joint use of T2 mapping and DKI.
