MRskanninger

MRskanninger, also known as Magnetic Resonance Imaging (MRI), is a non-invasive medical imaging technique that utilizes strong magnetic fields and radio waves to produce detailed images of organs and tissues within the body. Unlike X-rays or CT scans, MRI does not use ionizing radiation, making it a safer option for repeated examinations or for sensitive patient groups. The process involves placing the patient inside a large, tube-shaped magnet. Radiofrequency pulses are then emitted, which cause the protons within the body's water molecules to align. As these pulses are turned off, the protons release energy, which is detected by the MRI scanner. Different tissues emit signals of varying strengths, allowing the computer to construct cross-sectional images.

MRI is highly effective in visualizing soft tissues, such as the brain, muscles, ligaments, and internal organs, where it can detect abnormalities like tumors, inflammation, or injuries with remarkable clarity. It is widely used in neurology for diagnosing conditions like multiple sclerosis, stroke, and brain tumors. In orthopedics, MRI is invaluable for assessing joint damage, ligament tears, and spinal cord issues. The procedure typically takes between 15 to 90 minutes, depending on the area being scanned and the complexity of the images required. Patients may be asked to remain still for the duration of the scan, and some may experience mild discomfort from the enclosed space or the loud noises produced by the machine.
