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.
