Liver diffusion MR with intravoxel incoherent motion (IVIM) was performed using multiple b-values (b=0, 25, 50, 75, 100, 200, 500, 800) in 119 patients from June 2010 to May 2011. During the period, 29 patients underwent liver MR twice, and 9 out of 119 patients underwent liver diffusion MR in free breathing (FB) and respiratory triggering (RT). After obtaining IVIM derived parameters, we assess the difference between parameters in FB and those in RT. Also we assessed the reproducibility of IVIM derived parameters. Finally IVIM derived parameters were compared in liver cirrhosis group and non-cirrhotic group.
