A magnetic susceptibility phantom with a large range of negative to positive susceptibility values relative to water is demonstrated for validating quantitative susceptibility mapping (QSM) and related quantitative MRI techniques.
Structure and reconstructed susceptibility map of the phantom used for demonstration of mixing effects. MEDI reconstruction showed good agreement with COSMOS recon.
