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?

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.

 |
Magnetic resonance imaging(MRI) scanners rely on the principles of atomic nuclear-spin resonance. Using strong magnetic fields and radio waves, MRI collects and correlates deflections caused by atoms into images.
|
|
Magnetic resonance imaging(MRI) is a unique and versatile medical imaging modality. Doctors can obtain highly refined images of the body''s interior using MRI.

Detailed information on eye examinations in children Children are different than adults in that a child's brain develops more rapidly. Any problems a child may experience with his/her vision may disrupt the development of visual pathways to the brain. A critical stage of visual development occurs between birth and age 3 to 4 months, during which time the brain must receive clear visual messages from both eyes. Early detection and treatment can prevent loss of vision, learning difficulties, and delayed development.

Detailed information on visual screening tests in children Newborn babies arrive equipped with wonderful abilities to see and hear. Although their vision is not as sharp as that of an adult, newborn babies show responses to adult faces in the earliest days of life. Babies also have remarkable responses to sounds. They startle with loud noises and become quiet to the mother's voice.
