This study presents a new highly accelerated 3d saturation recovery first-pass perfusion using balanced steady state free precession (Fiesta) pulse sequence. Saturation was carried out through a 8ms adiabatic BIR4 radio frequency pulse. Acquisition was carried out at 3Tesla using a 32 channel cardiac coil, which allow 4-fold acceleration factor. Good image quality and CNR was obtained in three subjects anticipating a clinical validation of this pulse sequence
