Nuclear Cardiology

What Is Nuclear Cardiology? 

Nuclear cardiology involves imaging tests that use a small dose of radioactive material to visualize your heart. These scans help evaluate blood flow and detect any blockages in the coronary arteries. 

Why Is This Test Performed? 

Your healthcare provider may recommend a nuclear stress test to: 

• Identify coronary artery disease (CAD) 
• Detect areas with limited blood supply to the heart muscle 
  
• Evaluate heart function after a heart attack 

What to Expect During the Procedure 

• A radioactive tracer is injected into a vein in your arm 
• A specialized camera captures images of your heart both at rest and after physical activity 
• If you’re unable to exercise, medication may be used to simulate the effects of exertion 
• The entire test typically lasts a few hours, and you can return home the same day 

Understanding the Results 

Your doctor will analyze the images to assess how well blood is reaching your heart. If any issues are found, they may suggest further diagnostic tests or treatment options.
