Multispectral analysis of multiparametric MRI (mpMRI) images is being explored as an approach to objectively quantify intratumoral heterogeneity. However, acquisition of multiple co-registered parameters maps such as T1, T2, T2* and ADC for this task can be time-consuming. We propose a joint reconstruction method that exploits shared structural information between co-registered MRI parameter maps that provides high similarity between multispectral clusters defined on parameter maps from undersampled data and the ground truth fully-sampled maps of M0, T1, T2 and T2*.
