We evaluated the difference in the enhancement effect of the abdominal solid organ and the major vessel on DCE-MRI obtained with Gd-EOB-DTPA and Gd-DTPA. The relative enhancement (RE) of the abdominal solid organ including liver, and aorta at arterial-phase as well as the RE of portal vein and IVC at portal-phase in the Gd-EOB-DTPA images were significantly lower than those in the Gd-DTPA images. Conversely, the RE of liver at equilibrium-phase was significantly higher in Gd-EOB-DTPA than in Gd-DTPA. When using Gd-EOB-DTPA in the DCE-MRI, differences of the enhancement effect and the enhancement pattern of solid organs with Gd-DTPA need to be considered.
