An inversion recovery bSSFP measurement allows to generate a spectrum of the apparent relaxation time T1* and hence to identify multiple components in a voxel. However, it is not possible to extract unambiguous T1 and T2 information for each individual component. Here, we demonstrate that this limitation can be overcome by an additional bSSFP measurement without inversion pulse. Additive and subtractive combinations of the measured signal courses provide enough information for assigning unambiguous T1, T2 and proton density values to each component. In that way, 2D T1-T2 correlation spectra can be generated voxel-wise in a very time-efficient manner.
