A key question of magnetic resonance fingerprinting (MRF) is the appropriate choice of sequence parameters to achieve a high sensitivity to the tissue parameters of interest. In this contribution, different candidates for a measure of MRF sequence encoding capability are evaluated. While interpretation of measures that rely on local or global dot products proved difficult, a ‘brute force’ Monte Carlo approach showed good agreement with experimental results. By restricting this Monte Carlo method to small local dictionaries, substantial acceleration could be achieved.
