MR-STAT is a quantitative MRI technique that obtains multiple tissue parameter maps (e.g. T1, T2) from a single, short scan. In this study we perform an accuracy and repeatability study of MR-STAT using a Cartesian FISP-based sequence by repeatedly scanning Eurospin gel tubes and comparing the results against reference measurements. We observe coefficients of variation between 0.5 % and 1.5 % for T1 and between 2.0 % and 7.2 % for T2. The mean relative errors as compared to the reference measurements are -1.5 % for T1 and 5.8 % for T2.
