Hepatobiliary or Gallbladder Scan (HIDA Scan) at Swedish

Information and Preparation Instructions

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. You will be lying on your back for approximately 1 to 2 hours for the images. Please wear loose, warm, comfortable clothing. The technologist will inject a radioactive tracer through the I.V. and images begin immediately. The radiotracer will not cause any allergic reaction or discomfort. Based on the results of the first 1 hour of images, you may receive Kinevac (CCK, synthetic version of a hormone that your body produces to contract the gallbladder). CCK will be infused for 30 minutes followed by an additional 1-minute picture. If you are not given CCK, a small amount of morphine will be administered followed by an additional 20 minutes of imaging. If you have an allergy to morphine, please let the technologist know.
