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.
