3D Magnetic Resonance Fingerprinting with a Clustered Spatiotemporal Dictionary
Proceedings of the International Society of Magnetic Resonance in Medicine (ISMRM), Singapore, May 2016 (bib)

We present a method for creating a spatiotemporal dictionary for magnetic resonance fingerprinting (MRF). Our technique is based on the clustering of multi-parametric spatial kernels from training data and the posterior simulation of a temporal fingerprint for each voxel in every cluster. We show that the parametric maps estimated with a clustered dictionary agree with maps estimated with a full dictionary, and are also robust to undersampling and shorter sequences, leading to increased efficiency in parameter mapping with MRF.
