Kidney Fibrosis and MRI

The investigators plan a prospective cross-sectional study of pediatric and adult healthy volunteers and patients with chronic kidney disease that will correlate a variety of quantitative MRI biomarkers with severity of renal insufficiency and available histopathology. Over 3 years, the investigators will recruit approximately 20 healthy volunteers, 20 patients with chronic kidney disease (CKD) Stage 2-5, and 20 patients with renal transplant kidneys. The investigators also plan to assess the effect of inflammation on the quantitative MRI biomarkers by recruiting approximately 20 additional patients with active lupus nephritis.
