PET Oncology/Infection Scan at Swedish

Information and Preparation Instructions

Please arrive in the Radiology department 45 minutes prior to the exam 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. Please wear loose, warm, comfortable clothing free of metal. An injection of a radioactive tracer is given immediately. The radiotracer will not cause any allergic reaction or discomfort. The technologist will bring you a warm blanket and you will be asked to remain quiet and relaxed in a recliner chair for approximately 45 minutes while the radiotracer circulates in your system. Following this resting period, you will be asked to empty your bladder. You will then be taken into the scanning room and asked to lay on your back for images. The images will take 30 to 45 minutes.
