|
Your doctor may order evoked potential tests to check the signals your brain and spinal cord (parts of your nervous system) receive from other parts of your body. These tests are also used to check for vision and hearing problems.
|
|
The results of your hearing test are shown on a graph called an audiogram. This graph shows which types of sounds you can and can't hear. Hearing aids are prescribed based on the results of your audiogram. A sample audiogram is provided below.

 |
Magnetic resonance imaging(MRI) is a noninvasive way to take pictures of the body.Unlike x-rays and computed tomographic( CT) scans, which use radiation, MRI uses powerful magnets and radio waves. The MRI scanner contains the magnet.
|
|
Cardiac nuclear imaging is also called a "perfusion scan.” A radioactive tracer is delivered into the bloodstream. Then a camera scans the tracer in the blood as it flows through the heart muscle.

New MRI machines and new techniques result in images that show prostate cancer in much greater detail, allowing biopsies to be targeted more precisely, and thus cancer staging can be more accurate as well.
|
|
Magnetic resonance imaging (MRI) is a test that lets your doctor see detailed pictures of the inside of your body. MRI combines the use of strong magnets and radio waves to form an MRI image.

When I had an MRI of my knee, I was told the test was dangerous for people who have metal devices in their bodies. Since then, I developed angina and my cardiologist put in a metal stent. If I need an MRI in the future, will I be able to get one?
|
|
A Harvard Medical School physician answers your question about the safety of MRIs for those who have stents.
|
|
Studies have found that MRI tests used in addition to mammography detected more cancers in women at high risk for breast cancer. Women at average risk would not necessarily benefit from the additional testing.
|
|
Persons with pacemakers cannot get an MRI because it conflicts with the pacemaker's function. Future pacemakers will likely be made MRI-safe, but this will probably take at least several more years.
|
|
Is a regular MRI more accurate then an open MRI?
Diana Post, M.D., is an assistant professor of medicine at Harvard Medical School and a member of the Department of Medicine at Brigham and Women's Hospital.

How safe is it for a baby who is 6 months old to have an MRI?
Claire McCarthy, M.D., is a senior medical editor for Harvard Health Publications. She is an instructor in pediatrics at Harvard Medical School, an attending physician at Children's Hospital of Boston, and co-director of the pediatrics department at Martha Eliot Health Center, a neighborhood health service of Children's Hospital. The author of two books, "Learning How the Heart Beats" and "Everyone's Children", Dr. McCarthy was a regular columnist for "Sesame Street Parents Magazine" from 1995 to 1998 and is currently a contributing editor for "Parenting Magazine".
