ABSTRACT:
A method of obtaining a separate data contribution from first and second spectral components during a single magnetic resonance scan. The method uses a scan sequence causing the data from the first and second spectral components to be 90 degrees out of phase. This shift of the data along with a measurement of the inhomegeneities of the field initiates two output signals which are used to provide all of the data required for imaging the two spectral components and/or correcting images for chemical shifts.
