3D
MR thermometry using PRF shift has issues due to the requirement of
relatively long TE and the presence of fat. A hybrid method combining 2DRF
pulse, parallel imaging, and UNFOLD in a 3D sequence is proposed here, which
offers advantages in terms of spatial coverage and measurement accuracy, as
compared to typically-used 2D sequences.
