What a Breast MRI Is
MRI is short for Magnetic Resonance Imaging. MRI is a very useful type of diagnostic imaging exam and can be used for a variety of reasons. The sensitivity of MRI to changes in soft tissue, as well as its very high resolution, allow for the visualization of changes that may not be seen in other imaging exams. MRI excels at imaging soft tissues such as the breasts. While MRI is a very powerful and versatile technology, it is not used in all circumstances. Your doctor will let you know if MRI is the right exam for you.
MRI does not use ionizing radiation, as CT scans and x-rays do. Instead, MRI generates images using a very strong magnet and radio waves. The images are cross sections like CT scans, but MRI can also produce images in lengthwise planes without the patient having to change position.
Breast MRIs require the use of a contrast medium, also referred to as gadolinium. Gadolinium, which is given intravenously (IV), highlights certain types of tissue so the radiologist can better see any abnormalities. As with any other intravenously administered substance, the possibility of a reaction exists. However, documented reactions to MRI contrast media are very rare.
Not everyone may have an MRI. Due to the strong magnet used, some implanted materials and devices are not safe to image. Before you undergo an MRI, you will be asked to complete a questionnaire to ensure that it is safe for you to have an MRI.
Conventional MRI machines have a donut shape with a tube that is usually about 3 feet in length. This exam causes anxiety for some people who are claustrophobic. While Invision Sally Jobe has an Open MRI scanner, breast MRIs must be done on a conventional MRI machine. A typical breast MRI evaluation lasts approximately 40-45 minutes, and you must be able to hold reasonably still while lying prone for this time. For claustrophobic patients, a mild sedative may be used to help them relax.
Invision Sally Jobe offers Breast MRI at several of our outpatient centers in the South Denver
Metro area of Colorado.
