Calibrationless B1 Mapping for Accurate Macromolecular Proton Fraction Mapping Using Relaxometry Constraints

Macromolecular proton fraction (MPF) is an established myelin marker with confirmed clinical relevance, but with sensitivity to technological variations such as B1 field errors. We propose a method to derive B1 map for MPF correction from MPF data itself. The method is based on standard two-pool MT formalism enhanced with improved relaxometry constraints.
