Computed tomography (CT) scanning can better define renal masses and cysts usually noted on ultrasonography. Also, CT scanning is the most sensitive test for identifying renal stones. Intravenous (IV) contrast–enhanced CT scans should be avoided in patients with renal impairment to avoid acute kidney injury; this risk significantly increases in patients with moderate to severe CKD. Dehydration also markedly increases this risk.
