Phase-based magnetic resonance thermometry is used for monitoring minimally invasive ablation therapies like focused ultrasound therapy. MRT is prone to errors when applied in tissues with high fat content (e.g. breast tissue, fatty liver) due to heat-induced susceptibility changes. Therefore, there is a need for developing well characterized adipose tissue mimics that could serve as standards for validation of MRT techniques. In this study we showed that all measured adipose tissue mimics are representative of human adipose tissue with similar chemical spectra and thermal dependence of susceptibility shift and are reproducible standards for human adipose tissue validation MRI techniques.
