Technical recommendations on clinical renal MRI
Aims
This task force develops and maintains technical recommendations on how to measure renal MRI biomarkers on clinical scanners. If you are starting a clinical study, you will find here concrete guidelines on how to set up the acquisition, and you can be reassured that the approach will be accepted by a broad body of experts in the field.
We expect this to lead to a significant improvement in efficacy of research by eliminating the need for local development and optimisation. It will also form a driver for a more standardised approach, improving comparability of results by different teams, and establishing a common benchmark to evaluate future developments.
The task force is led by Steven Sourbron (chair) and Pim Pullens (co-chair).
Status
A process for developing consensus-based recommendations has been defined, published and applied to Relaxometry, Diffusion, Arterial Spin Labelling, BOLD and Phase-Contrast MRI. Currently we are working on setting up a process to update the recommendations and make compliant protocols available. This includes the setup of a Study Group on renal MRI within the International Society of Magnetic Resonance in Medicine (www.ismrm.org), that will maintain the recommendations in the future.
Process
Consensus formation in this task force follows a predefined process that is written out in an open access publication:
- Mendichovszky, I., Pullens, P., Dekkers, I. et al. Technical recommendations for clinical translation of renal MRI: a consensus project of the Cooperation in Science and Technology Action PARENCHIMA. Magn Reson Mater Phy 33, 131–140 (2020). https://doi.org/10.1007/s10334-019-00784-w
The process includes the formation of expert panels for each MRI technique, who will develop an initial set of consensus statements (version 1.0) following a Delphi-like process and informed by a systematic review of the literature. After publication of version 1.0, the panels will remain in existence and update the recommendations if and when substantial new evidence emerges that justifies a new round of consensus formation.
Recommendations
Technical recommendations has been completed for renal ASL, DWI, T1 & T2 mapping, BOLD and Phase contrast. The first four are reported in a special issue on renal MRI published by MAGMA in January 2020:

Reviews
All recommendations build on systematic review papers that are published separately. The review for PC was produced by this task force and is published here:
- Villa, G., Ringgaard, S., Hermann, I. et al. Phase-contrast magnetic resonance imaging to assess renal perfusion: a systematic review and statement paper. Magn Reson Mater Phy 33, 3–21 (2020). https://doi.org/10.1007/s10334-019-00772-0
Protocols
The task force also collects detailed technical specifications of MRI acquisition protocols compliant with the recommendations. A Github repository is created to collect the protocols. A placeholder release of the repository was created in Zenodo when the recommendations were submitted and this will be updated with a new formal release once a more complete set is available.
If you have a protocol that is compliant with the recommendations, and would like to make it available through this repository, please follow the instructions provided in the Github repository page.
Updating of recommendations
We are currently working on a process for updating the recommendations in light of new evidence.
Expert panels
The role of the expert panel is to develop recommendations for individual methods, review submitted protocols for compliance with the recommendations, and review requests for new recommendations or updates of existing recommendations. The panels are open to participation of any expert with a track record in the relevant field. If you want to join a panel, please contact the panel chair.
