The study compares a fast 3D VIBE sequence with Dixon fat saturation and CAIPIRINHA acceleration techniques (3D VIBECAIPI-DIXON) to a standard 2D FLASH sequence with spectral fat saturation and conventional GRAPPA acceleration technique (2D FlashGRAPPA-fs) for non-enhanced imaging of the pancreas in an intra-individual clinical setting. Qualitative assessments and semi-quantitative signal ratio measurements were performed. To complement this clinical data, we acquired quantitative phantom measurements to obtain objective signal-to-noise ratios. 3D VIBECAIPI-DIXON enables robust pancreatic imaging with an acquisition time of 12 seconds, providing homogenous fat suppression and a higher pancreas to fat signal ratio than conventional 2D FlashGRAPPA-fs.
