The study will have three stages.
Stage 1: 45 people with CKD from nine UKRIN centres will undergo multiparametric MRI to test patient tolerance, data completeness and central data collection processes.
Stage 2: A multicentre, prospective cohort study of 450 people with CKD, collecting multiparametric renal MRI at baseline and 2 years. Long-term outcomes will be determined with efficient tracking of kidney failure events via the UK Renal Registry at 5 and 10 years.
Stage 3: A mechanistic sub-study of 45 patients (from Stage 2) who have had a routine renal biopsy. Detailed comparisons will be made between multiparametric MRI and histopathological changes. Tissue blocks will undergo quantitative analysis of fibrosis, capillary density and inflammation using immunohistochemistry techniques.
