Standardisation and multicentre evaluation of renal MRI measures is crucial for clinical translation. Here we present results of a Travelling kidney study on GE, Philips and Siemens using a harmonised multiparametric renal MRI protocol, and show results of B0 and B1 mapping, T1, and T2* mapping. The mode B0 within the kidneys did not vary across vendors, however the FWHM was narrower for Vendor 1. No significant differences were seen in MOLLI T1 values of the renal cortex and medulla after this data was corrected for the offset in T1 seen in the NIST phantom.
