What does cardiac magnetic resonance imaging show?

The medical professional supervising your scan will provide your doctor with the results of your cardiac MRI. Your doctor will discuss the findings with you.

Cardiac MRI can reveal various heart conditions and disorders, such as:

  • Coronary heart disease
  • Damage caused by a heart attack
  • Heart failure
  • Heart valve problems
  • Congenital heart defects
  • Pericarditis
  • Cardiac tumors

Cardiac MRI is a fast, accurate tool that can help diagnose a heart attack. The test does this by detecting areas of the heart that don't move normally, have poor blood supply, or are scarred.

Cardiac MRI can show whether any of the coronary arteries are blocked, causing reduced blood flow to your heart muscle. Currently, coronary angiography (an-jee-OG-ra-fee) is the most common procedure for looking at blockages in the coronary arteries. Coronary angiography is an invasive procedure that uses x-rays and iodine-based dyes.

Researchers have found that cardiac MRI can replace coronary angiography in some cases, avoiding the need to use x-ray radiation and iodine-based dyes. This use of MRI is called MRI angiography.
