MRI stands for Magnetic Resonance Imaging. It is a diagnostic imaging test that uses a magnetic field and radio waves to create detailed images of the body's internal organs and tissues.
During an MRI, the person lies on a table that slides into a cylindrical machine. A strong magnetic field and radio waves are used to create detailed, cross-sectional images of the inside of the body. Unlike CT scans and X-rays, MRI does not involve exposure to ionizing radiation.
MRI scans are commonly used to diagnose and monitor various conditions, including injuries, infections, tumors, and other abnormalities. They can also be used to guide certain medical procedures, such as biopsies and surgeries.
MRI is a safe and non-invasive test, but it is not recommended for people with certain medical conditions, such as pacemakers, cochlear implants, and metallic fragments in the eyes or body.
Interpreting an MRI requires specialized training and expertise. A radiologist or other healthcare provider who is trained in reading imaging studies typically reviews the MRI results and makes a diagnosis based on the images.
