Synopsis

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 T₁values of the renal cortex and medulla after this data was corrected for the offset in T₁ seen in the NIST phantom.
