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.
An MRI is a test that uses a magnetic field and pulses of radio wave energy to make pictures of the spine. In many cases, an MRI gives different information than an X-ray, an ultrasound, or a CT scan. An MRI also may show problems that cannot be seen with other imaging tests.n some cases, a contrast material may be used during the MRI to show certain parts of the body more clearly. The MRI can find changes in the spine and in other tissues. It also can find problems such as infection or a tumor.
