Abstract

In conventional weighted MRI, the presence of multiple species within a single voxel can alter signal intensity. However, it remains difficult to determine the species content which gives rise to this intensity change due to similarity in exponential-shaped signal evolutions. The uniqueness of signal evolutions generated through Magnetic Resonance Fingerprinting (MRF) allows for the identification of multiple species present within a single voxel. Here we demonstrate that MRF is able to resolve multiple material components from single, mixed voxels and validate the derived tissue fractions in a realistic simulation model.
