title: Opacification of the gallbladder following intravenous contrast injection in patients with normal renal function.
abstract: Gallbladder opacification from vicarious excretion of urographic contrast agents may indicate decreased renal function. Doses of contrast material greater than 12.5 g, however, provide enough iodine for visualization of the gallbladder in patients whose renal function is normal. Gallbladder opacification following the administration of urographic contrast material when renal function is normal has no pathologic significance.
