Structural measurements should
be done with the 64-channel head coil, whereas functional measurements should
be done with the 20-channel head coil. The influence of the prescan normalize
filter depends on the task and the region of interest.
(a) Highest beta estimates in each ROI for the three tasks, pooled over
coils. Larger beta estimates without prescan normalize in motor and visual
cortex, but no difference in auditory cortex and the opposite pattern in thalamus.
(b) Beta estimates for the two coils pooled over tasks. The same pattern
holds for both coils. (mot = motor, aud = auditory, vis = visual task, ON/OFF = with/without
prescan normalize)
Normalized tSNR maps for the 20-channel head coil (a,b) and the
64-channel head coil (c,d) with (ON) and without (OFF) prescan normalize.
