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
