Technetium-99m-labeled octreotide acetate scintigraphy in the whole body planar view. This was performed 3 hours after injection of 15mCi technetium-99m-labeled octreotide acetate. There is a focal uptake in the lower lobe of our patient's right lung, just above his diaphragm, highly suggestive of an adrenocorticotropic hormone (ACTH)-producing bronchial tumor.
