This work describes a novel method accounting for MR acquisition
properties (B0, B1+,B1-,T1,T2*)
to perform concentration measurements in the framework of in vitro Phosphorus MRI. Our pipeline uses a non-Cartesian 3D sequence
for efficient signal sampling and a wavelet regularized least square method for
reconstruction. We demonstrated within
an acceptable time for human experiment, for 5mm isotropic resolution, that we
are able to calibrate and measure absolute 31P concentrations.
