A synthetic radio-frequency (RF) signal, which is received along with the ¹H magnetic resonance (MR) signal in magnetic resonance imaging (MRI), is used to determine absolute tissue water and lipid quantities. We show application of this ERETIC method (electronic reference to access in vivo concentration) to musculoskeletal imaging, with the potential to better track disease progression in Duchenne Muscular Dystrophy (DMD), and other muscle pathologies.
