This study showed comparable in-vivo reproducibility
of 3D MRF reconstructed using two different dictionary resolutions in most
brain parenchyma. Yet, lower reproducibility was evident in CSF measurement, notably
in a higher resolution dictionary.

of average DARTEL-normalized T1 and T2 maps of all healthy volunteers
reconstructed by using low-density and high-density dictionaries. Consistencies
were evident in most brain parenchyma.
