Chemical
shift-encoded imaging is a quantitative method commonly used to estimate fat
fraction (FF) in various body parts. However, for a reliable assessment, this
technique requires short inter echo spacing which can be challenging if high
spatial resolution is desirable. An alternative quantitative method, based on the
difference in T2-relaxation time between fat and water, was examined and
compared to the chemical shift-encoded imaging method. This T2-based technique successfully
estimated FF in phantoms at high resolution and large matrix size, when the chemical
shift-encoded method failed.
