Magnetic Resonance Imaging (MRI) uses a magnetic field and computer-generated radio waves, not radiation, to create 3D images of organs and tissues. These detailed images show both hard and soft tissues. MRI scans are used to diagnose injuries, as well as illnesses that affect bones, joints, muscles, organs, and other soft tissues. Because the MRI procedure produces images of the internal body without the use of radiation, it is safe for any age group.
MRI and Cancer
An MRI procedure plays an important role in both cancer diagnosis and treatment planning. It is important to note, not all tumors are cancerous. An MRI can differentiate normal and diseased tissue to precisely pinpoint cancerous cells within the body. It is also useful for revealing metastases (if cancer has spread).
Upon careful review of the images, a doctor can then plan the most appropriate cancer treatment for his or her patient. This treatment may include surgery, radiation, and/or chemotherapy. The most important factor to a successful outcome is to fully understand the situation at hand so the doctors can develop the most effective treatment strategy. Because each cancer journey is unique, each journey requires a specialized treatment plan to provide the highest success rate possible.
Your doctor may use imaging scans during diagnosis and treatment to:
- Look for cancer in an early stage
- Help find tumors (abnormal growths, masses, or lumps) in the body
- Help find out the stage of cancer
- Help your doctor choose your treatment plan
- Show if the tumor has changed during treatment to help your doctor know if the treatment is working
- See if a cancer has returned after treatment
How Does an MRI Work?
The MRI machine looks like a long, open-ended, narrow tube. You lie down on a movable table that slides into the tube. An MRI technician monitors you from another room. The MRI technologist can see, hear, and always speak with you. In most cases, you may also have a friend or relative stay in the room with you if you wish.
Inside the tube is a large, strong magnet. Once inside the tube, you are surrounded by a very powerful magnetic field. During the scan, the MRI machine creates bursts of radiofrequency waves which, combined with the magnetic force, pick up signals from the hydrogen atoms in your body. A computer then translates these signals and converts them to black and white “pictures.” These pictures are cross-sectional and taken from many angles. In some cases, a contrast material, typically gadolinium, may be required and injected intravenously. The contrast material enhances certain details and is especially useful in detecting brain and spinal cord tumors.
Detecting Breast Cancer
A specific breast MRI produces detailed images of the breast tissue, detecting cancer or any other abnormalities that may be present. For certain women at high risk for breast cancer, a breast MRI may be requested by a doctor along with a yearly mammogram. In addition to being useful in detection of some cancers it is also helpful in identifying benign (or non-cancerous) tissue. This reduces unnecessary additional tests and/or biopsies.
As with most things in life, knowledge is a powerful tool. And an MRI can provide you and your medical team invaluable information that will offer you the best chance for a positive outcome. Detection is the first step. Millions of MRI scans are performed in the U.S. each year. It is a common procedure that exists for your health and well-being.
