The purpose of this study is to extend the 2D MR
Fingerprinting (MRF) and MRF-Music framework to 3D
acquisitions. Both methods were originally implemented
in 2D acquisitions and have shown high scan efficiency
for quantifying multiple tissue properties
simultaneously. In addition to the multi-parameter
quantification in MRF, the MRF-Music sequence was
proposed to provide musical sounds that can dramatically
improve the patients experience in the MR scanner. In
this study, the MRF and MRF-Music sequences were
implemented to achieve 3D coverage while still
maintaining a high scan efficiency and providing
desirable sounds. T1 and T2 values from phantom studies
of the 3D slab selective MRF and MRF-Music methods
showed good agreement to the values from the standard
measurements. The T1, T2, off-resonance and M0 maps from
3D non-selective MRF and MRF-Music also showed promising
results of achieving 3D isotropic quantitative mapping.
