Cardiac Magnetic Resonance Imaging

What is Cardiac Magnetic Resonance Imaging?

Cardiac magnetic resonance imaging (MRI) uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the structures within and around the heart. Doctors use cardiac MRI to detect or monitor cardiac disease.

Symptoms

The magnetic fields and radio waves used in a cardiac MRI have no significant side effects and are not harmful to most people. For those who may have a slight risk of complications, our Stanford care team works with all of our patients to ensure a safe experience.

Complications

MRI contrast may have an effect on other conditions, such as allergies, asthma, anemia, low blood pressure, kidney disease, and sickle cell disease. Nephrogenic systemic fibrosis (NSF) is a very rare but serious complication of MRI contrast use in people with kidney disease or kidney failure

Causes

MRI has proven valuable in diagnosing a broad range of conditions, including cardiovascular anatomical anomalies (e.g., congenital heart defects), functional abnormalities (e.g., valve failure), tumors, and conditions related to coronary artery disease and cardiomyopathy (disease affecting the heart muscle).

Risk factors

Have a pacemaker or other implantable device. The doctor can determine if the device is safe for MRI tests.
Are in the first three months of pregnancy.
Are breastfeeding and contrast dye will be used in the MRI.

Prevention

Nothing metal or electronic is allowed inside MRI room.
Patients are required to change into MRI safe clothing MR safety.
Patients are required to bring medical implant cards.
Powerful magnetic field is always ON.

How is it diagnosed?

What is a heart MRI? A heart MRI is a scan of your heart in which radio waves and magnets create images without anything you can see or feel going into your body. A cardiac MRI can show the parts of your heart (including chambers, valves and muscles) and how well they are working ― including how your blood moves.

How is it treated?

Treatment for acute myeloid leukemia is vital. It varies with the patient and stage of the disease. Treatment options include

You will lie very still on a table.
The table will slide into a large cylinder (the MRI machine)
Detailed pictures of your heart and blood vessels are taken.
You'll be instructed to hold your breath for 10 seconds as each picture is taken.
