The purpose of this study is to quantify multiple MR parameters in a single acquisition in a short acquisition time by combining the MR Fingerprinting (MRF) with a rapid spiral readout. MRF is a novel approach that can quantify multiple parameters (e.g. T1, T2, proton density and off-resonance) of a material or tissue simultaneously. This study uses single-shot spiral MRF method to reduce the acquisition time to around 10 seconds. Because of the robustness of pattern recognition, the parameter maps have shown high rejection of severe undersampling artifacts.
