Magnetic Resonance Imaging (MRI)
The key tool in helping identify MS lesions.
The key tool in helping identify MS lesions.
Magnetic Resonance Imaging (MRI) produces images of your insides. Unlike an X-ray, which emits radiation to produce an image, an MRI uses an oscillating (a fancy word for “moves around a central point,”) magnetic field. This magnetic field excites the nuclei (another fancy word for “center”) of your cells, releasing a radio signal (crazy, right?) that produces an image. MRIs are especially important in MS for visualizing lesions (sites of injury) in the brain and spinal cord.
