✦ Synopsis

Abstract

Chemical‐shift artifact correction methods for multislice F‐19 imaging with perfluorooctyl bromide are described and results obtained with physical phantoms presented. Utilization of the two long‐T2 spectral peaks of PFOB in multislice imaging enhances the imaging efficiency considerably. Simultaneous imaging of the adjacent slices is achieved by appropriately adjusting the slice selection gradient amplitude, the bandwidth, and the slice position offset frequency of the selective RF pulses in relation to the frequency separation between the two peaks. © 1992 Academic Press, Inc.

## 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
