A method for chemical-shift-selective imaging.
Selective suppression of a given resonance in an NMR image can be obtained with a pi/2 pulse whose excitation spectrum is zero at the appropriate chemical shift. The selective pi/2 pulse presented here is composed of two nonselective pi/2 pulses of opposite phase. The two pulses are separated by a short interval which determines the excitation spectrum.
