Purpose of this study is in vivo acceleration of T2
parameter mapping. To achieve this purpose, random
undersampled mask is applied on the pulse sequence of 2D
multi-echo spin echo. The images are reconstructed using
compressed sensing algorithm with patch based low-rank
penalty. And common mono-exponential fitting is used to
generate T2 map. The acceleration times are remarkably
reduced.
