Previously, MR Fingerprinting (MRF) has been presented
as a new method for simultaneous quantitative mapping of
different physical MR properties. In this study, the T1
and T2 values of MRF were compared to conventional T1-
and T2-mapping methods in the brains of five volunteers
at 1.5T. Each volunteer was measured five times with a
TrueFISP and a FISP based spiral MRF sequence, an
MP2RAGE and a multi echo spin echo sequence for
conventional T1 and T2 maps, respectively. Both MRF
sequences showed a similar reproducibility but seemed to
slightly underestimate the T2-values in comparison to
the conventional sequences.
