What is Magnetic Resonance Imaging?
Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. During the scan, you lie on a table that slides inside a tunnel-shaped machine. Doing the scan can take a long time, and you must stay still. The scan is painless. The MRI machine makes a lot of noise. The technician may offer you earplugs.

Magnet Therapy
Many civilizations throughout history have used magnets to treat illness. Ancient Egyptian priests and the fourth century Greek physician Hippocrates documented the use of magnets. The 15th century Swiss physician and chemist Paracelsus hypothesized that magnets may attract diseases out of the body. Read more on

Magnetic Resonance Imaging
History of MRI Working independently, Felix Bloch of Stanford University and Edward Purcell of Harvard University made the first successful nuclear magnetic resonance experiment to study chemical compounds in 1946. Dr Bloch and Dr Purcell were awarded the Nobel Prize for Physics in 1952. In the early 1980s, the first "human" magnetic resonance imaging (MRI) scanners became available, producing images of the inside of the body. Current MRI scanners produce highly detailed 2-dimensional and 3-dimensional images of the human anatomy.

MRI
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. The magnetic field produced by an MRI is about 10 thousand times greater than the earth's. The magnetic field forces hydrogen atoms in the body to line up in a certain way (similar to how the needle on a compass moves when you hold it near a magnet). When radio waves are sent toward the lined-up hydrogen atoms, they bounce back, and a computer records the signal. Different types of tissues send back different signals. Single MRI images are called slices. The images can be stored on a computer or printed on film. One exam produces dozens or sometimes hundreds of images. For more information, see the specific MRI topics: Abdominal MRI Chest MRI Cranial MRI Heart MRI Lumbosacral spine MRI Spine MRI

Abdominal MRI scan
A magnetic resonance imaging (MRI) scan of the abdomen is a noninvasive method to create detailed pictures of the inside of the belly area.

The magnetic field produced by an MRI is about 10 thousand times greater than the earth's.

Heart MRI
Heart magnetic resonance imaging (MRI) is a imaging method that uses powerful magnets and radio waves to create pictures of the heart. It does not use radiation (x-rays). The test may be done as part of a chest MRI. Unlike x-rays and computed tomographic (CT) scans, which use radiation, MRI uses powerful magnets and radio waves. The MRI scanner contains the magnet. The magnetic field produced by an MRI is about 10 thousand times greater than the earth's. The magnetic field forces hydrogen atoms in the body to line up in a certain way (similar to how the needle on a compass moves when you hold it near a magnet).
