The purpose of this study is to determine the usefulness of SPIO enhanced diffusion weighted imaging (DWI:b=500) for detection and characterization of the hepatic metastasis.Specificity and Az value of post-contrast DWI was significantly superior to pre-contrast DWI. Detection and characterization of hepatic metastases were improved with SPIO enhanced diffusion weighted MR images.
