In essence, MRI measures the water content (or fluid characteristics) of different tissues, which is processed by the computer to create a black and white image. The image is highly detailed and can show even the smallest abnormality.n MRI scan works by using a powerful magnet, radio waves, and a computer to create detailed images. Your body is made up of millions of hydrogen atoms (the human body is 80% water), which are magnetic.
MRI is used to diagnose a variety of disorders, such as strokes, tumors, aneurysms, spinal cord injuries, multiple sclerosis and eye or inner ear problems, according to the Mayo Clinic. It is also widely used in research to measure brain structure and function, among other things.What makes MRI so powerful is, you have really exquisite soft tissue, and anatomic, detail, said Dr. Christopher Filippi, a diagnostic radiologistat North Shore University Hospital, Manhasset, New York.iffusion MRI. This form of MRI measures how water molecules diffuse through body tissues. Certain disease processes â such as a stroke or tumor â can restrict this diffusion, so this method is often used to diagnose them, Filippi said. Diffusion MRI has only been around for about 15 to 20 years, he added.
