T2 magnetization preparation and spectrally selective fat suppression sequences are commonly used to enhance the imaging contrast. Increased B1 inhomogeneity at 3 T necessitates a preparation sequence that is more robust with respect to B1 inhomogeneity. We propose a spectrally selective B1 insensitive T2 Prep sequence for imaging at 3T. Numerical simulations, phantom and in-vivo images acquired using this technique are presented.
