Arterial spin labelling (ASL) is a unique MR approach for quantifying tissue perfusion non-invasively. However, it is prone to motion-related artefacts which limit its application in the clinical domain, especially outside the brain. In this work, we combine a motion-insensitive ASL acquisition scheme with a specifically tailored retrospective motion correction pipeline. This enabled repeatable renal perfusion measurements to be obtained in the first ASL study in paediatric patients with moderate/severe chronic kidney disease.
