Absolute quantification of R1 and R2 relaxation rates and proton density PD has been gaining considerable attention in recent years. It is of utmost importance that these measurements entirely reflect patient properties and no influence is detectable on which specific MRI scanner system the quantitative maps were obtained. The SyMRI software was verified on Philips, GE and Siemens scanners at both 1.5T and 3T showing cross-system reliability.
