A multiparametric phantom for quantitative MRI and magnetic resonance fingerprinting was developed. Solutions of PVP were used to tune the apparent diffusion coefficient (ADC), and then doped with Mn to control T₁ and T₂. The addition of Mn did not affect the ADC, but did significantly shorten T₁ and T₂, demonstrating the potential of independently tuning relaxation times and ADC.
