DCE-MRI, IVIM and DKI are emerging as promising tools for tumor diagnositic or therapy-predictive purposes. We performed these three methods in patients with rectal cancer simultaneously to find out their correlations. Our results showed significant correlation between perfusion sensitive parameters of IVIM and DCE-MRI. In addition, DKI parameters were calculated from data with a low (0-1000) and high (200-2000) b-value range, and the parameters from low b-value range showed significant correlation with IVIM parameters, but not for the high b-value range.
