What To Expect

Thyroid Uptake Scan:
What to expect: The study involves two separate appointments. The radioactive isotope will be given to you the morning of the first day and a time will be scheduled for you to return the next day to complete the study. Each visit should last about 30 minutes. Do not eat or drink for one hour after taking the isotope. After 1 hour has passed, it is suggested that you drink plenty of fluids to flush your system.

Hepatobiliary Scan/HIDA Scan:
What to expect: The scan will last about 90 minutes. You will receive the medicine intravenously while lying on your back on the scan table. A gamma camera will be positioned over your abdomen throughout the scan.

Bone Scan:
What to expect: The study involves two separate appointments. The radioactive isotope will be administered intravenously during the first visit, and an appointment will be scheduled for you to return to complete the scan 3 to 6 hours after the injection. The scan will take between 30 and 60 minutes.

Gastric Emptying Study:
What to expect: You will eat a small amount of oatmeal containing the radioactive isotope, which allows the oatmeal to be viewed by a gamma camera. You will then sit upright in a chair for about 60 minutes while the camera photographs your abdomen.

Heart Scan:
What to expect: The radioactive isotope will be administered intravenously. The study involves two parts: stress (chemical or physical) and rest. You will be asked to walk on a treadmill to physically stress your heart. If you are unable to walk, a chemical will be used to induce the stress instead. The isotope will help form an image of your heart both at rest and during exercise.

A radiologist will interpret your images and send the results to the physician who ordered the procedure.

There are no known long-term adverse affects from the low dose of radiation in these studies.
