What is GRAPPA?
GeneRalized Autocalibrating Partial Parallel Acquisition
Will combine multi-coils to become bigger coil
Reduce scanning time
Alternative Way Instead of GRAPPA
Open Protocol — Routine
Adjust the averages by reducing the value (1 step)
Example: Current value 2 — become 1
However, this will reduce the SNR value.
To gain the SNR value, increase the Phase Oversampling by 50%
The SNR value should be around 1. Should not reach 2 or below 1.
