Comparing the pre- and post-MRI
Magnetic resonance imaging
Magnetic resonance imaging is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from CT or CAT scans and PET sca…

What are the white spots on my MRI?
White spots may be described in your MRI report as high signal intensity areas (HSIA), white matter hyperintensities, leukoaraiosis (often used if spots are felt to be caused by decreased blood flow), or nonspecific white matter changes. They are usually found in the brain’s white matter, typically near the ventricles.

White matter disease is the wearing away of tissue in the largest and deepest part of your brain that has a number of causes , including aging. This tissue contains millions of nerve fibers, or axons, that connect other parts of the brain and spinal cord and signal your nerves to talk to one another. A fatty material called myelin protects the fibers and gives white matter its color.
