Water or Fat selective 3D-bSSFP imaging combined with banding artifact correction on small-animal at 7T

To obtain fat-free MR images on small animals, several techniques have been developed. Low SNR, susceptibility arfetacts and echo time value restrictions limit their application at high magnetic field. 3D-bSSFP MR sequence, generating high signal in short acquisition time, was performed after a frequency-selective binomial pulse at 7T. Water-selective or fat-selective mouse whole-body 3D-bSSFP images were obtained with no banding artefacts due to the combination with Sum-Of-Square technique. Chemical shift artifact was removed allowing for better delineation and quantification of lymph node volumes. In addition, tumors growing in the renal sup-capsule were easily identified from abdominal fat.
