Computerized tomography (CT) and magnetic resonance imaging (MRI) both provide 3-D, high-resolution images to help your provider diagnose and plan for your treatment. These tests are more advanced and reliable than traditional cardiac testing, and there is less chance of missing an issue. They help doctors visualize your heart better and determine what procedure is needed.
This non-invasive imaging test looks at the coronary arteries. During a CT angiography, an intravenous injection of contrast is used along with X-ray to produce 3-D images of the heart and blood vessels.
During a cardiac CT scan, an X-ray machine moves around your body and takes a picture of each part of your heart. A computer puts the pictures together to make a 3-D picture of the whole heart.
MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of your heart, instead of ionizing radiation (X-rays). MRI is used to help your provider detect and monitor cardiac disease. It allows for the evaluation of the heart and surrounding structures.
MRI can diagnose a variety of cardiovascular disorders, such as tumors and infections within the heart. Surgical metal in your body may interfere with MRI.
