Apparatus, methods, and other embodiments associated with the spectral analysis of T2 spectral data are described. One example magnetic resonance imaging (MRI) method includes accessing a data set comprising T2 spectral data associated with a magnetic resonance imaging (MRI) signal received from an object. The method also includes decomposing the T2 spectral data with multi-exponential functions to determine T2 spectra corresponding to the T2 spectral data. The T2 spectra are portioned into a plurality of intervals defined by the T2 spectral data acquired in a predetermined time period.
