The iBEAt study MRI biomarker panel has been developed to determine if imaging biomarkers can improve predictions of renal function decline in diabetic kidney disease. The aim of this pilot study was to inform the approach to quality control and image processing of iBEAt data. Repeatability in 5 healthy volunteers (4 scans per subject) was analysed with a prototype image-processing pipeline. The results indicated that repeatability of renal T1, T2* and phase-contrast renal blood flow was comparable to literature, and measurement precision was sufficient to detect differences between volunteers. ASL had poor repeatability presumably from B0 inhomogeneities in labelling plane.
