What is Magnetic Resonance Imaging?
Magnetic resonance imaging (MRI) is an imaging modality that uses magnetic fields and radio waves to create detailed images of the brain, joints, spinal cord, breasts, blood vessels and internal organs without ionizing radiation. MRI can be used in multiple ways to properly evaluate the area of concern. Depending on the symptoms, intravenous gadolinium (non-iodine) contrast or oral contrast can be used to gain more information. Because MRI uses magnetic fields, careful screening is required to assure your safety while in the MR scanner. You will be asked detailed questions about any metal/metallic devices that could be unsafe such as pacemakers, implants, prostheses, shrapnel, etc. For patients with claustrophobia, the examination can be difficult and this should be discussed with your doctor prior to the MRI examination. During an MRI scan, you will lie comfortably on a table that is moved inside a large magnet. A piece of equipment called a coil, which sends and receives the radio frequency waves used in this technology, will be placed around the area being examined. During the scan, you will hear various noises, ranging from a buzzing to a loud knocking which is normal to expect. You will be offered earplugs or headphones for music to diminish the background noise and to allow for a comfortable experience during testing. Our team of doctors and technologists are highly trained and prepared to assure your safety.

MR Angiography (MRA) is a study of the blood vessels that can be performed with or without intravenous gadolinium (non-iodine) contrast. Depending on your symptoms, your doctor may want an MRA to assess vascular patency, the presence of any narrowing or stenosis which could cause your symptoms or look for vascular abnormalities or malformations.
