In general, it is difficult to obtain functional information about water and lipid in tissues at the same time. We, therefore, developed a novel method using chemical shift displacement and recovery-based separation of lipid tissue (SPLIT) with different inversion times, echo times, and b-values to simultaneously acquire diffusion, perfusion, T₁, T₂, and lipid fraction in the calf. All parameters obtained with the SPLIT were consistent with previously reported values. This method enables simultaneous acquisition of functional information without special pulse sequence.
