Classification: CPC A  G | IPC A  G

Claim 13:
14. A method for using an open magnet Nuclear Magnetic Resonance (“NMR”) apparatus to obtain NMR response signals generated by atomic nuclei of substances comprising an organ, the NMR response signals comprising a fat contribution signal and a water contribution signal, the method comprising:
transmitting radio frequency (“RF”) pulses in a presence of a field gradient into the organ with the open magnet NMR apparatus;
obtaining the NMR response signals; and
measuring the NMR response signals' amplitude dependence with diffusion time;
determining amplitude and diffusion coefficients of fat and water contributions using the measured amplitude dependence with diffusion time;
computing a proton density fat fraction (“PDFF”) based on the determined amplitudes; and
determining water and fat composition of the organ based on the PDFF.
