Fast Field-Cycling MRI (FFC-MRI) has the ability to access contrast invisible to conventional scanners – that resulting from the dependence of T1 on magnetic field strength. Simulating FFC-MRI sequences by iteratively applying the Bloch equations as the magnetic field strength changes with time was found to give highly accurate predictions of signal intensity at the end of each cycle. This information was used to optimise parameters of the FFC-MRI scans.
