title: Correction of chemical-shift artifacts in multislice F-19 imaging with perfluorooctyl bromide.
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.
