This study proposes a simple and accurate dictionary creation method for MR fingerprinting using a fast Bloch image simulator. A typical MR fingerprinting sequence based on a FISP sequence and a numerical phantom were used for dictionary generation. Cartesian and spiral readout gradients were used for the Bloch image simulation of the numerical phantoms. MR fingerprinting parameter maps obtained by pattern matching with the dictionaries generated by the proposed method demonstrated validity and usefulness of the method. The proposed method is simple and useful for creation of accurate dictionaries in MR fingerprinting.
