The application of higher field strengths requires knowledge of the relaxation rates at these fields for proper adjustment of image acquisition parameters. We provide the first in vivo T1 relaxation maps of mouse brain at 17.6 T and compare those with measurements at 9.4 T. The implications on SNR and CNR are discussed, as is the overall effect of T1, T2 and proton density on gray/white matter contrast at ultra-high field.
