Various techniques for myelin mapping based on signal from the lipid-protein bilayer have been proposed, and a common way of validating these techniques is using ex-vivo tissue samples. However, it is still unclear to what extent experimental factors such as tissue storage conditions and processing affect MR signal. In this work, we investigate how long-term deep-frozen storage impacts tissue signal, and evaluate whether signal component mapping is feasible in non-D2O-exchanged samples. We also determine whether animal tissue can act as a substitute for human tissue and investigate signal differences between white and grey matter.
