3D stack-of-rings IR-SPGR fat-water-separated axial head images. The same brain volume was imaged with both protocol A and B. Good WM/GM CNR is observed and uniform fat/water separation is obtained over the whole brain for both protocols. Shown here is the central axial slice from both scans. Results from protocol B have higher SNR, as expected. The actual measured values are listed in Table 1.
