7T Anatomical Acquisitions
Acquisition
The default anatomical acquisition for the 7T study is the calculated MP2RAGE UNI DEN
(unified denoised, from 2 separate T1inv
). But, in the middle of the study, the acquistion protocol was failing. So we collected a standard T1w mprage.
They have the same resolution but the mp2rage has better signal to noise. In some places the mprage is incorrectly annotated as acq-lowres.
