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.
