Selective suppression of a given resonance in an NMR image can be obtained with a i ~/ 2 pulse whose excitation spectrum is zero at the appropriate chemical shift. The selective 7r/2 pulse presented here is composed of two nonselective i ~/ 2 pulses of opposite phase. The two pulses are separated by

Chemical shift imaging techniques are magnetic resonance imaging methods that separately map the spatial distribution of individual peaks or components in a complex NMR spectrum. A range of chemical shift imaging techniques based around the commonly employed spin-echo Fourier imaging sequences is cl

## Abstract An efficient magnetic resonance spectroscopic imaging (MRSI) or chemical shift imaging (CSI) technique based on multiple spin echoes (MSE) has been implemented, validated, and used in both phantom and in vivo MRβguided neurosurgical applications. The key concept of the method is to empl
