title: New etiology for intestinal uptake of thallium-201.
abstract: A patient with both rest and exercise thallium images for unstable angina demonstrated marked large intestinal uptake of thallium. However, the thallium uptake in the large intestine was noted only after exercise. The only change in the patient status between the two studies was the administration of verapamil. Thus, verapamil administration has been demonstrated to be a new cause for gut uptake of thallium.
