Heart imaging tests 

Depending on your heart problem, your doctor may recommend one or more of these advanced heart imaging tests (also called cardiac imaging tests):

  • Arteriogram: Uses an injectable contrast dye and X-ray images to show the location and severity of blocked blood vessels
  • Doppler ultrasound: Uses sound waves to reveal blocked blood vessels
  • Cardiac magnetic resonance imaging (MRI): Creates real-time 3D images of heart structure and functions
  • Chest X-ray: Shows heart damage, heart enlargement and fluid retention in lungs (pulmonary edema) caused by heart failure
  • Computed tomography angiogram (CTA): Uses an injectable dye and CT scan to reveal blood vessel blockages 
  • Echocardiogram (echo): Uses ultrasound to measure the heart’s pumping action, or ejection fraction
  • Electrocardiogram (EKG/ECG): Records the heart’s electrical activity to show heart enlargement or strain
  • Magnetic resonance angiogram: Uses magnetic and radio wave energy to take pictures of blood vessels
  • Multigated acquisition (MUGA) scan: A tracer, or injectable radioactive dye, helps to visualize and measure the heart’s pumping action, called ejection fraction 
  • Nuclear stress test: A radioactive dye and imaging tests show blood flow to the heart and evidence of coronary artery disease
  • Positron emission tomography (PET) scan: A tracer, or injectable radioactive dye, measures blood flow and oxygen intake
