Abstract
The signal from fat is suppressed by a CHESS pulse sequence that precedes each imaging pulse sequence in an MRI scan. The effectiveness of the suppression is optimized by calculating a flip angle for the ChemSat RF saturation pulse in the CHESS pulse sequence based in part on prescribed scan parameters, such as the number of interleaved slices to be acquired.
Claims10
A method for acquiring an image with an MRI system, the steps comprising:
- a) entering scan parameters for an imaging pulse sequence, said scan parameters including the number of interleaved slices to be acquired;
- b) calculating an optimal flip angle for a ChemSat RF saturation pulse, said calculation being based in part on the number of interleaved slices to be acquired;
- c) acquiring image data with the MRI system using the imaging pulse sequence and preceding each imaging pulse sequence with the ChemSat saturation pulse;
- and
- d) reconstructing an image with the acquired image data.
