Low spatial resolution and long acquisition time have
been the two major limitations for T1 mappings routine
application in clinical MRI. Recently several image
space and k-space based reconstruction methods have been
proposed to estimate T1 maps from undersampled data,
however, most of them dealing with single-shot
single-slice T1 mapping. In this work, a single-shot
sequential multi-slice acquisition scheme together with
a new relaxation model is proposed. After combining it
with radial undersampling and iterative reconstruction,
our method facilitates accurate, high-resolution
multi-slice T1 mapping.
