Abstract
Artifactual water signal intensity loss can be observed on fat-saturation m agnetic resonance (MR) images of inhomogeneous regions such as the thorax. Magnetic effects of air inclusions on fat-saturation pulses were investigat ed as the possible origin of this artifact. Computer simulation results agr eed well with observed production of water saturation by means of nominal f at suppression in MR imaging of phantoms and a representative clinical exam ple.
