Hallmark of management is prevention in at-risk patients.
Isotonic hydration with normal saline 1-1.5L (15ml/kg) prior to the contrast load in patients with impaired renal function may lessen the chances of developing<unk>  
If suspect the development or confirm the diagnosis continue adequate hydration to maintain urine output of 0.7cc-1cc/kg
Early research suggests a potential benefit for forced furosemide diuresis (300ml/h) while continuing intravenous hydration fluids (0.5mg/kg) but should be performed in consult with radiologist and nephrologist
