“…Hu and Parrish [16] proposed that this problem be solved by producing difference images of a small rectangular FOV containing the area of interest, thereby making it possible to subsample the k-space of the dynamic images. LF MRI is a more general approach, which can a b c Preliminary experiments [46] indicate that the 2-D version of LF MRI can be used to improve the quality of proton spectroscopic images of the head. These images are degraded by truncation artifacts from scalp lipids which obscure the weak signal from lactate in the adjacent brain cortex.…”
