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
