Magnetic Resonance Imaging
An MRI uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the inside of your body. The magnetic field temporarily realigns hydrogen atoms in your body. Radio waves cause these aligned atoms to produce faint signals which are used to create cross –sectional images-like slices in a loaf of bread.MRI is the most frequently used imaging test of the brain and spinal cord and it is often used to help diagnose Multiple Sclerosis, aneurysms, spinal cord injuries, disorders of the eye and inner ear, stroke, brain tumors, brain injury from trauma.
