The evolution of MRI, CT, and PET imaging and the availability of MDCT and fusion of PET and MDCT data sets as well as the MRI data sets have lead to gains in detection and characterization of hepatic lesions. To assess the added value of DW-MRI to PET/CT in the evaluation of patients with hepatic focal lesions, we included in our study 35 patients referred for assessment of hepatic focal lesions. The 35 patient underwent 18F-FDGPET/CT followed by triphasic CT and DW-MRI; images of both PET/CT and MRI were fused on the work station. A consultant radiologist and aconsultant nuclear medicine physician interpreted all the images independently
