We have demonstrated MR Fingerprinting at low magnetic
field, which results in simultaneous measurement of 4
quantitative parameters, and thus provides 4 different
image contrasts in a single acquisition (proton density,
T
1
, T
2
and
off-resonance) in less than 15 minutes. This technique
is of particular relevance at low magnetic field where
SNR and contrast are tied to long acquisition times. The
combination of MRF with low field MRI scanners has great
potential to revolutionize future transportable MRI
systems.
