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.

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?

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.
|
|
For women at high genetic risk, adding MRI screening to mammography may improve early detection of breast cancer.

|
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.

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".
