Utility of B0 images and BLADE, for T2-weighted scans in uncooperative patients

A multishot DWI with b=1000 reveals an infarct involving the left caudate head that age wise is < 7-10 days (demonstrating restricted diffusion, which was confirmed on the ADC map, not show). The b=0 image is slightly less blurred, on the basis of patient motion, given that this is a single image acquisition, as opposed to the b=1000 trace weighted image (which combines images acquired with diffusion weighting in the left-right, anterior-posterior, and superior-inferior dimensions). The conventional FSE T2-weighted scan shows marked patient motion artifact (ghosts propagating in this instance primarily from the high signal intensity of the fatty scalp). The BLADE image features markedly reduced ghosts, principally due to the rotation of k space acquisition.
