ARCF: Kidney Fibrosis and MRI
Study Details
Study Description
Brief Summary
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.

Other: Healthy Volunteers 20 healthy volunteers will be recruited and will receive a kidney MRI and the same blood and urine labs that are collected for the other arms. Results will be compared to the disease groups. |
Diagnostic Test: Kidney MRI
An MRI examination will be completed per research MRI protocol.
|
Other: Kidney Transplant 20 subjects that have received a kidney transplant that have had a biopsy performed within the past 12 months will be enrolled. They will receive a kidney MRI and will have blood and urine collected. |
Diagnostic Test: Kidney MRI
An MRI examination will be completed per research MRI protocol.
|
Other: Stage 2-5 CKD 20 subjects that have been diagnosed with stage 2-5 CKD and have had a biopsy performed within the past 12 months will be enrolled. They will receive a kidney MRI and will have blood and urine collected. |
Diagnostic Test: Kidney MRI
An MRI examination will be completed per research MRI protocol.
|
Other: Lupus nephritis 20 subjects that have that have active lupus nephritis and have had a biopsy performed within the past 12 months will be enrolled. They will receive a kidney MRI and will have blood and urine collected. Subjects that are post-lupus treatment will receive an additional MRI at the time of the next biopsy. |
Diagnostic Test: Kidney MRI
An MRI examination will be completed per research MRI protocol.
