A three-dimensional projection reconstruction pulse sequence acquires two half echoes in a steady state free precession (SSFP) scan. A method for combining the two echoes to suppress either fat or water in the reconstructed image is described includes shifting the phase of one echo and combining them in a regridding process used to transform the radial data to a Cartesian grid prior to image reconstruction.

Magnetic resonance imaging with fat suppression

Two images are acquired using a three-dimensional projection reconstruction, SSFP pulse sequence. Different RF phase cycling patterns are used to acquire each image and a fat suppressed water image is produced by combining the two images. Data acquisition efficiency is increased by aquiring k-space data during substantially the entire readout gradient waveform produced during the SSFP pulse sequence.
