While
the use of IR-TrueFISP to quantify the relaxation parameters T1 and T2 and
the proton density M0 has been demonstrated, these values can be difficult to
quantify in species with fast relaxation because the first points along the
relaxation curve are hard to assess.
This abstract explores the use of the recently proposed technique
through-time radial GRAPPA to reconstruct highly undersampled radial images
acquired along the relaxation curve. In this way, the first few points after
the inversion can be assessed and the relaxation parameters more accurately
quantified.
