Blood-oxygen-level-dependent MRI enables noninvasive assessment of renal deoxyhaemoglobin levels and, therefore, hypoxia. As decreased tissue oxygenation might contribute to acute and chronic kidney disease (CKD), this tool has been examined in patients with CKD. Indeed, the benefits of renin–angiotensin–aldosterone system inhibitors might be partly conferred by increased oxygenation.
