How can radionuclide ventriculography test for heart failure?

ANSWER

During a radionuclide ventriculography, radioactive materials go into your bloodstream. Then a gamma camera takes pictures of your heart to show how well it's working. The radioactive material is safe for most people. But if you're pregnant or nursing, you shouldn't get this test.
