Intravoxel incoherent motion (IVIM) MR imaging is a non-invasive method with the ability of separation of pure molecular diffusion and perfusion effects. Radiologists perform diffusion-weighted and dynamic contrast-enhanced (DCE) MRI to provide additional diffusion and perfusion information in the routine clinical set, but it needs intravenous contrast agent administration and requires cumbersome procedures. Therefore, in this study we applied the IVIM technique to detect the prostate cancer and to compare the diagnostic performance between IVIM and conventional DWI combined with DCE. Our results demonstrated combination of D and f seemed to be more efficient than the clinical conventional DWI combined with DCE method in the diagnosis of prostate cancer
