In this work, k-t PCA is demonstrated to be a promising acceleration technique for MR relaxation measurements, since the dynamics along the relaxation curve can be described by only a small number of principal components. In-vivo IR-TrueFISP experiments for quantitative T1, T2 & M0 parameter mapping acquired with up to 8-fold acceleration by using the k-t PCA concept are presented.
