Detailed explanation-1: -Magnetic resonance imaging (MRI) is another diagnostic imaging technique that produces cross-sectional images of your body. Unlike X-rays and CT scans, MRI works without radiation. The MRI tool uses magnetic fields and a sophisticated computer to take high-resolution pictures of your bones and soft tissues.
Detailed explanation-2: -X-rays and CT scans both use a small dose of ionizing radiation to produce images. An MRI scan, however, doesn’t work this way. It uses powerful magnets and radio waves to create the images instead of ionizing radiation. So, you are not exposed to radiation when you have an MRI scan, unlike a CT scan or x-ray.
Detailed explanation-3: -The MRI scan provides clear and detailed images of soft tissue. However, it can’t ‘visualise’ bone very well, since bone tissue doesn’t contain much water. That is why bone injury or disease is usually investigated with regular x-ray examinations rather than MRI scanning.
