Limited available time of the MRI system, large numbers of needed animals, or instable models, often make shorter measurement times necessary.
Longer measurements times are often needed to achieve sufficient SNR when using lower field strengths. Using UHF, measurement times can be significantly shortened, since, for example, an increase in sensitivity by a factor of two allows to acquire images with the same resolution and similar quality in a quarter of the time [5]. Therefore, the number of data averages can be reduced, and the time saved can be invested into additional subjects or further studies.
