An MRI scan (Magnetic Resonance Imaging) is a non-invasive diagnostic imaging procedure that uses a strong magnetic field and radio waves to create detailed images of organs, tissues, bones, and other structures inside the body. Unlike X-rays and CT scans, MRI does not use ionizing radiation.
What Is an MRI Scan Used For?
Doctors may recommend an MRI test to evaluate a wide range of conditions affecting the brain, spine, joints, muscles, abdomen, pelvis, and other parts of the body. Common examinations include brain MRI, spine MRI, joint MRI, and abdominal or pelvic MRI. MRI can help doctors assess injuries, inflammation, tumors, neurological conditions, and soft-tissue abnormalities.
What to Expect During an MRI
Before the scan, you may be asked about your medical history, implants, and any metal objects. Depending on the examination, a contrast agent may be recommended to improve image visibility. During the procedure, you lie on a movable table that enters the MRI scanner. The scan may take around 20–60 minutes depending on the body part and type of examination.
