Shunt Patency Test at Swedish

Information and Preparation Instructions

Please arrive in the Radiology department prior to the exam for the admissions process. A nuclear medicine technologist will greet you for the appointment. The radionuclide tracer will be injected by a neuroradiologist directly into a shunt (a small amount of hair will be removed to allow for a sterile environment). Please wear loose, warm, comfortable clothing free of metal. The radiotracer will not cause any allergic reaction or discomfort. Imaging begins immediately after injection and will take approximately 30 to 60 minutes.
