The effects of EOB on T2WI, DWI, and balanced FFE were assessed at both 1.5 T and 3T scanners to optimize imaging parameters in EOB-enhanced liver MRI. SNR in the images and ADC values were severely affected by EOB concentration. The filed-strength of scanner affected patterns of neither SNR nor ADC changes. Imaging parameters should be carefully chosen for EOB-enhanced T2WI, DWI, and balanced FFE.
