The water-only phantom images (b-d) using the SPSP pulse excitation along with the reference image (a) using the normal RF pulse in bSSFP sequence (Note that the presence of an air bubble causes a bright spot at the top of fat phantom. It also appears in Fig. 3 as a dark spot). Imaging parameters: FOV=15cm, flip angle=35°, slice thickness=8mm and matrix size=128×128. (a) reference image with TE/TR=2.6/5.2ms; (b) water-only image using the 3×720μs SPSP pulse with TE/TR=2.2/4.4ms; (c) water-only image using the 4×800μs SPSP pulse with TE/TR=2.8/5.6ms; (d) water-only image using the 5×720μs SPSP pulse with TE/TR=2.8/5.6ms.
