The purpose of this study is to use MRF method to
potentially mitigate the acoustic noise problem in
normal MR scans while simultaneously quantifying
multiple tissue parameters. Instead of producing quiet
sequences, we instead take advantage of the extra
degrees of freedom in MRF to design acquisitions to
replicate music in the magnet. In this study, mp3 music
files, which are converted to arbitrary readout encoding
gradients, are used with varying flip angles and TRs in
the MRF exam to quantify T1, T2, off-resonance and
proton density maps simultaneously while providing
pleasing sounds to the patient.
