Information and Preparation Instructions

This test is to identify a pheochromocytomas and neuroendocrine tumors. Please arrive in the Radiology department for the admissions process. A nuclear medicine technologist will greet you for the appointment. A small intravenous (I.V.) line will be started by the technologist for the exam. The technologist will inject a radioactive tracer through the I.V. The radiotracer will not cause any allergic reaction or discomfort. After the injection, you will be instructed to return at 4 hours and 24 hours (there is a slight chance you may have to return at 48 hours post injection). During these wait times, you may eat or drink as usual and resume normal activities. Imaging at 4 hours will be approximately 30 minutes. Imaging at 24 hours will be approximately 45 to 60 minutes.
