A
comparison of the SNR in DTI images acquired with a cryogenic coil and a room
temperature (RT) surface coil and a comparison performed by qualitative
assessment of the calculated fractional anisotropy (FA)-maps at different
spatial resolutions were performed on mice brain at a 9.4 T animal scanner.
The SNR of the cryogenic coil was about threefold higher compared to the SNR
of the RT surface coil and the quality of the FA-maps acquired with a high in
plane resolution and the cryogenic coil were significantly improved compared
to the RT-coil.
