What is the primary function of MRI machines?

The primary function of MRI machines is to employ strong magnetic fields and radio waves to generate detailed images of the body's internal structures. Unlike other imaging modalities, such as X-rays or CT scans, MRI does not utilize ionizing radiation; rather, it leverages the magnetic properties of hydrogen atoms in the body. When placed in a magnetic field, these atoms align and emit signals when disturbed by radio waves. These signals are captured and processed to create high-resolution images of soft tissues, organs, and other structures within the body.

This unique capability makes MRI particularly valuable for diagnosing conditions related to the brain, spinal cord, and joints, as well as for evaluating soft tissue injuries. The safety profile of MRI, due to the absence of radiation exposure, contributes to its widespread use in medical imaging.
