Sodium relaxation times have been shown to be
altered in several diseases. Hence, 2D sodium relaxometry using Magnetic Resonance Fingerprinting (23Na-MRF) was demonstrated
recently as a proof of concept. In this work an extension to a 3D sequence is presented.
Furthermore, a more complex signal model based on irreducible spherical tensor
operators was investigated. The feasibility of simultaneous 3D quantification
of T1, T2s*, T2l*, T2*
and ΔB0 was demonstrated in phantom measurements.
