PURPOSE: We aimed to reveal the difference in contrast enhancement of the abdominal organs and major vessels on dynamic contrast-enhanced magnetic resonance imaging (DCM-MRI) using gadoxetic sodium (Gd-EOB-DTPA) and gadopentetate dimeglumine (Gd-DTPA) in the same patients. MATERIALS AND METHODS: DCM-MRI using Gd-EOBDTPA and Gd-DTPA were performed in the same 17 patients. Precontrast and DCM-MRI images [arterial phase (AP), portal venous phase (PP), hepatic venous phase (HP)] were acquired before and after bolus injection of each contrast agent. The organ-to-muscle ratio [liver (L/M), spleen (S/M), aorta (A/M), portal vein (P/M), hepatic vein (V/M)] were calculated at each phase and analyzed statistically. RESULTS: There was no significant difference between Gd-EOB-DTPA and Gd-DTPA images regarding the L/M or V/M mean on precontrast images or the mean of L/M at AP and L/M at the PP. At the AP, PP, and HP, the means of S/M, A/M, P/M, and V/M with Gd-EOBDTPA were lower than those with Gd-DTPA. On HP, The mean L/M with Gd-EOB-DTPA was higher than that with Gd-DTPA. CONCLUSION: On 3-T DCM-MRI using Gd-EOB-DTPA, contrast enhancement of the organs, except for the liver, was lower than that on DCM-MRI using Gd-DTPA. The HP was already affected by hepatobiliary uptake in Gd-EOB-DTPA.
