Magnetic therapy, also called magnetic field therapy and bioenergy therapy, is an alternative therapy that uses magnets of varying sizes and strengths that are placed on the body to relieve pain and treat disease. Thin metal magnets are attached to the body alone or in groups. They can be worn as bracelets or necklaces, attached to adhesive patches to hold in place, placed in bands or belts to be wrapped around the wrist, elbow, knee, ankle, foot, waist, or lower back. Also available are magnetic insoles, blankets, and slumber pads. These magnets may be worn for just a few minutes or for weeks, depending on the condition being treated and the practitioner. Proponents state the magnetic fields produced from the negative pole of the magnet have healing powers. Negative magnetic fields are thought to stimulate metabolism, increase the amount of oxygen available to cells, and create a less acidic environment within the body. Conditions diagnosed or treated include arthritis, cancer, circulatory disorders, diabetic neuropathy (nerve disease), fibromyalgia, HIV/AIDS, immune dysfunction, infection, inflammation, insomnia, multiple sclerosis, muscle pain, neuropathy, pain, rheumatoid arthritis, sciatica, stress and to increase energy and prolong life. Although there are anecdotal reports of healing with magnetic therapy, available scientific evidence does not support these claims. The U.S. Food and Drug Administration (FDA) considers magnets harmless and of no use for medical purposes.
- Magnetic resonance elastography
An imaging technique used to measure the elasticity of tissue by gently shaking the tissue in a magnetic resonance imaging (MRI) machine. The technique employs standard MRI equipment with a few modifications and a vibrating metal plate placed on the skin. Magnetic resonance elastography (MRE) works by measuring the wavelength of the vibrations sent through […]
- Magnetic resonance imaging
A procedure that uses magnetism, radio waves, and a computer to create pictures of areas inside the body. Abbreviated MRI. An MRI is painless and has the advantage of avoiding x-ray radiation exposure. There are no known risks of an MRI. The benefits of an MRI relate to its precise accuracy in detecting structural abnormalities […]
- Magnetic resonance perfusion imaging
A special type of magnetic resonance imaging (MRI) that uses an injected dye in order to see blood flow through tissues.
- Magnetic resonance spectroscopic imaging
(MRSI) A noninvasive imaging method that provides information about cellular activity (metabolic information). It is used in oncology along with magnetic resonance imaging (MRI) which provides information about the shape and size of the tumor (spacial information). Also called 1H-nuclear magnetic resonance spectroscopic imaging and proton magnetic resonance spectroscopic imaging.
- Magnetic-targeted carrier
A tiny bead made from particles of iron and carbon that can be attached to an drug. A magnet applied from outside the body then can direct the drug, for example, to the site of a tumor. This can keep a larger dose of the drug at the tumor site for a longer period of […]
