What is this test?
This test combines magnetic resonance imaging (MRI) of the chest without contrast and magnetic resonance angiography (MRA) with intravenous contrast. MRI produces detailed pictures of organs and tissues, while MRA focuses on blood vessels.
Why might I need this test?
A clinician may order these studies to investigate chest structures, blood vessels, or unexplained symptoms. Possible reasons include evaluating masses, inflammation, congenital abnormalities, or narrowing or blockage of blood vessels.
How is the test performed?
You will lie on a movable table inside an MRI scanner and may need to remain still while several sets of images are taken. For the MRA portion, contrast material is given through a vein in your arm, and the scanner rapidly captures images of the blood vessels.
How do I prepare for the test?
Follow the facility's instructions about medications, eating, and drinking; fasting is not usually required unless specifically requested. Tell the imaging team if you are pregnant or breastfeeding, have kidney disease, or have had a reaction to contrast material, and disclose any medically implanted devices or metal in your body.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may involve the lungs, chest organs, or blood vessels and can be associated with conditions such as infection, inflammation, structural abnormalities, or impaired blood flow. Results are interpreted by a radiologist together with your symptoms, examination, and other tests, so an abnormal finding does not by itself establish a diagnosis.
