Method for optimizing fat suppression using the chemical shift selective MR imaging technique

摘要

The signal from fat is suppressed by a CHESS pulse sequence that precedes each imaging pulse sequence in an MR1 scan. The effectiveness of the suppression is optimized by calculating a flip angle (204) for the ChemSat RF saturation pulse (10) in the CHESS pulse sequence based in part on prescribed scan parameters, such as the number of interleaved slices to be acquired. <IMAGE>
