PASTA uses a combination of low rf excitation bandwidth and alternate excitation and refocus slice selection gradient polarities to remove fat signal via chemical shift. PASTA++ is an improved version of PASTA designed for 3T. Using 3T-tailored rf pulse choices and irregular echo spacing, PASTA++ can be included in an fast spin-echo readout with short echo spacing. PASTA++ delivers high SNR images with uniform fat suppression even in the presence of B0 inhomogeneity. Since PASTA++ does not use a prepulse, it delivers fat suppression immune to B1- and T1-variation without increasing SAR.
