Nuclear Stress Tests

A nuclear stress test is a medical procedure used to evaluate the blood flow to the heart muscle both at rest and during stress. It involves injecting a small amount of radioactive material (a tracer) into the bloodstream, which allows doctors to visualize the heart’s blood flow using a special camera.

The test typically involves two parts: one during rest and another after exercising (or with a medication that simulates exercise for those who can’t physically exercise). By comparing images from both states, doctors can identify areas of the heart that may not be receiving enough blood, indicating potential blockages or other cardiac issues.
