Rapid Fat Suppression in MRI of the Breast with Short Binomial Pulses
University of Utah
A method of water-only excitation is presented for MRI of the breast which achieves effective fat suppression for gradient recalled echo imaging in minimum time with the use of short binomial pulses. In contrast to conventional binomial frequency-selective pulses, these short pulses are applied without interpulse delay, allowing for very rapid spectrally selective excitation. Results are presented showing effective water excitation and fat suppression in breast MRI at 3.0 Tesla with total excitation time of 160 microseconds.
