Synopsis: MR Fingerprinting (MRF) has been shown to be extremely efficient in generating multiple parametric maps. Here we explore MRF using a FISP-based sequence with a spiral trajectory to generate T 1 , T 2 , and M 0 maps simultaneously. The result shows that high quality quantitative relaxation parameters can be estimated using the proposed method. With the introduction of the additional unbalanced gradients, the sequence is insensitive to inhomogeneities in the main magnetic field. This method has its potential to expand the areas of application of MRF, and extend the quantification to other MR parameters.
