MRI Scan: A Comprehensive Guide
MRI Scan: A Comprehensive Guide Magnetic Resonance Imaging (MRI) is a powerful diagnostic tool used in modern medicine to create detailed images of the body's internal structures. Unlike X-rays and CT scans, MRI does not use ionizing radiation; instead, it relies on strong magnetic fields and radio waves to generate high-resolution images of organs, tissues, and bones. How MRI Works An MRI scanner is a large, tube-shaped machine that houses a powerful magnet. When a patient enters the scanner, the magnetic field aligns the hydrogen atoms in the body. Radiofrequency waves then stimulate these atoms, causing them to emit signals that are detected by the machine. A computer processes these signals to create detailed images of the scanned area. Uses of MRI MRI is used for diagnosing and monitoring a wide range of medical conditions, including: Brain and Neurological Disorders : Detecting tumors, strokes, multiple sclerosis, and other brain abnormalities. Spinal Conditions : I...
