This study aimed to demonstrate the effect of dielectric pad on MR images of the upper abdomen at 3T regarding the improvement of B1 inhomogeneity. 10 healthy volunteer were scanned at 3T scanner using HASTE, T1-FLASH, Fat sat T1 FLASH, and diffusion weighted images. Images obtained with different dielectric pad made of ultrasound gel, water and without pad were compared regarding signal uniformity. The use of pads improved the B1-inhomogeneity in images on HASTE, and DWI, while no significant differences were observed on T1-FLASH images. There were no significant differences between the two different dielectric pads on all sequences.
