After a resting and exercise radionuclide angiogram (RNA) -- a type of nuclear medicine procedure that evaluates the heart's chambers in motion -- you should move slowly when getting up from the scanner table to avoid any dizziness or lightheadedness from lying flat for the length of the procedure.

You will be instructed to drink plenty of fluids and empty your bladder frequently for 24 to 48 hours after the test to help flush the remaining radionuclide from your body.

The intravenous (IV) site will be checked for any signs of redness or swelling. If you notice any pain, redness, and/or swelling at the IV site after you return home following your procedure, you should notify your physician as this may indicate an infection or other type of reaction.

Your physician may give you additional or alternate instructions after the procedure, depending on your particular situation.
