title: Visualization of an adrenal pheochromocytoma with thallium-201.
abstract: An adrenal pheochromocytoma was visualized with thallium-201 chloride. Tl-201 concentration was observed in the cellular and vascular portion of the tumor immediately after its intravenous injection and decreased with time. Tl-201 may be a useful imaging agent for localizing pheochromocytomas.
