MR contrast agents are typically imaged
using time-consuming sequences, which allows only one parameter of relaxation
to be assessed. In this research we used Magnetic Resonance Fingerprinting
(MRF) to rapidly assess both T1 and
T2, and
these values were then used to calculate contrast agent concentrations. The
primary goal was to quantify two contrast agents residing in a mixed sample.
The method showed an accuracy greater than 90% in most cases,
indicating its feasibility. In addition, the method was also able to
quantify the bound and unbound state of a targeted contrast agent in near
real-time.
