MRI (Magnetic Resonance Imaging) Print

Magnetic Resonance Imaging (MRI) is a technology that allows radiologists to acquire images of the inside of the body using the body’s own magnetic properties. In contrast to conventional x-rays, MRI permits evaluation of much more than simply bones in the body; it provides detailed information about soft tissues, muscles, ligaments, tendons, organs, and blood vessels.

What are some common uses of the procedure?

  • MRI is an excellent tool for evaluation of disorders of the brain and spine.
  • MRI is widely used to diagnose very small tears or other injuries to ligaments and muscles around the knee, shoulder, hip, elbow, ankle, and wrist.
  • MRI of the heart, aorta, coronary arteries and blood vessels is a fast, noninvasive tool for diagnosing coronary artery disease and heart problems.
  • Organs of the chest and abdomen can also be examined in high detail with MRI, allowing the diagnosis and evaluation of tumors and certain functional disorders.

How much radiation do I get from an MRI exam?

None. An MRI exam uses magnets to measure the small magnetic changes in your own body to generate detailed images. Magnetic resonance imaging does not rely on ionizing radiation.

How long is the MRI exam?

Most studies take 20-45 minutes. Depending on what part of the body is studied, it may take as long as two hours. When you schedule your appointment, the schedulers and technologists will be happy to explain your anticipated procedure time in more detail.
