 Abstract: MR Fingerprinting signal evolutions can be used to estimate partial volumes of tissues in addition to tissue relaxation times. Two approaches to tissue fraction estimation, a pseudoinverse calculation and dictionary-based or constrained solution, are quantitatively compared in the presence of four potential error sources. The constrained approach is found to more accurately estimate tissue fractions, and also to improve segmentation of pathology.
