Parameter mapping can be acquired rapidly by MR fingerprinting. It requires a pseudo random pulse sequence to build an unique dictionary between the evolution of signal and parameters. The problem can be simplified when the dimension of the dictionary is relatively low. Here, we propose a dictionary that accelerates T2 mapping with dictionary and conventional sequence.
