MRI scanners, or Magnetic Resonance Imaging scanners, are advanced medical machines used to create detailed images of the inside of the body. They use strong magnets and radio waves to produce clear pictures of organs, tissues, and even the brain. This non-invasive technique helps doctors diagnose various conditions without the need for surgery. During an MRI scan, patients lie on a table that slides into a large, tube-shaped magnet. The process is painless, but it can be noisy. MRI scanners are particularly useful for examining soft tissues, making them essential tools in fields like neurology and orthopedics.
