Abstract
A method for improving fat saturation during magnetic resonance imaging (MRI) by placing a fat saturation enhancing material such a fluorocarbon, preferably perfluorooctylbromide, perfluorodecylbromide, FC-77, or FC-43 on or around a part of the body (1) of a patient to be scanned with MRI, thereby eliminating the skin-air interface and reducing anatomical imaging problems. The placement of the fat saturation enhancing material may be accomplished by enclosing the material in a container (10) which may also contain the MRI coil.
