Purpose The potential of renal MRI biomarkers has been increasingly recognised, but clinical translation requires more
standardisation. The PARENCHIMA consensus project aims to develop and apply a process for generating technical recommendations on renal MRI.
Methods A task force was formed in July 2018 focused on fve methods. A draft process for attaining consensus was distributed publicly for consultation and fnalised at an open meeting (Prague, October 2018). Four expert panels completed
surveys between October 2018 and March 2019, discussed results and refned the surveys at a face-to-face meeting (Aarhus,
March 2019) and completed a second round (May 2019).
Results A seven-stage process was defned: (1) formation of expert panels; (2) defnition of the context of use; (3) literature
review; (4) collection and comparison of MRI protocols; (5) consensus generation by an approximate Delphi method; (6)
reporting of results in vendor-neutral and vendor-specifc terms; (7) ongoing review and updating. Application of the process
resulted in 166 consensus statements.
Conclusion The process generated meaningful technical recommendations across very diferent MRI methods, while allowing for improvement and refnement as open issues are resolved. The results are likely to be widely supported by the renal
MRI community and thereby promote more harmonisation
