✦ Synopsis

The role of susceptibility effects in the production of artifacts in chemical shift images generated by the selective excitation technique is discussed. The effects are demonstrated in images of phantom samples of agarose gels containing small air bubbles. The artifacts can lead to erroneous interpretations, in which the resonances to be resolved exhibit a relatively small chemical shift separation, such as that between water and soluble carbohydrates (sugars).

## Abstract Chemical shift artifact (CSA), familiar to radiologists along the frequency‐encoding axis, also occurs along the section‐select axis. The authors observed a case in which CSA mimicked a renal mass. Subsequent retrospective analysis of 50 abdominal magnetic resonance (MR) imaging studies

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

## Abstract One of the difficulties encountered in ^19^F NMR imaging of fluorinated blood substitutes is that these compounds often exhibit complex multipeak spectra. These peaks result in chemical‐shift artifacts along the readout direction and blurred images. In addition, each peak excites a diff
