We present a comparison of different pattern matching algorithms for tissue characterization based on Magnetic Resonance Fingerprinting. The applicability of a simple dot product approach and a number of machine learning algorithms is investigated for different parameter regimes. We find that, in many cases, machine learning algorithms can offer higher accuracy and faster matching.
