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

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.
