An MRI (Magnetic Resonance Imaging) scan is a scan that uses only magnetic and radio waves. There is no exposure to x-rays or any other damaging forms of radiation.
I had one done some years ago as severe nerve damage was suspected in my back.
The scan can provide detailed pictures of almost all the tissue in the body including bone tissue, thus it is particularly useful for spinal cord and brain scans for detecting, for example, tumors.
