Electron resonance imaging

Electron Resonance Imaging (MRI) is a special kind of scanner that takes pictures of your inside body. It works by using powerful magnets and radio waves to make a detailed picture of the inside of your body. MRI can look at your body in different ways, so doctors can use it to look for problems like cancer and other diseases. MRI scans are painless and can provide more information than an X-ray.
