Comment: If a pheochromocytoma is suspected, then IV contrast is not routinely used. Reactions to nonionic contrast in patients with pheochromocytoma are very rare, however. The entire abdomen is scanned if the adrenal glands are negative. Special attenuation is paid to the liver; a site of vascular metastases. When you scan the entire abdomen use IV contrast to detect sites of metastases.
