Parathyroid Scan at Swedish

Information and Preparation Instructions

This exam is for the identification of single or multiple adenomas, or the localization of primary or secondary parathyroid cancer. 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. and images will begin 15 to 20 minutes later. The radiotracer will not cause any allergic reaction or discomfort. A series of images will be taken for approximately 1 hour. You will then be asked to return 3 hours later. During this time, you may eat or drink as normal. When you return, the second series of images will take approximately 45 minutes.p>
