MRInä

MRInä is a Finnish term often used informally to refer to an MRI (Magnetic Resonance Imaging) scan. An MRI is a non-invasive medical imaging technique that uses a strong magnetic field and radio waves to create detailed images of the organs and tissues within the body. It is commonly employed for diagnostic purposes, helping healthcare professionals identify a wide range of medical conditions affecting the brain, spinal cord, muscles, joints, and internal organs. Unlike X-rays or CT scans, MRI does not involve ionizing radiation, making it a preferred method for imaging soft tissues and for patients who require repeated imaging. The procedure typically involves lying on a table that slides into a large, tube-shaped magnet. The magnetic field aligns the protons in the body's water molecules, and radio waves are used to briefly knock these protons out of alignment. As the protons realign, they emit signals that are detected by the MRI scanner and processed by a computer to generate cross-sectional images. The process can take anywhere from 15 minutes to over an hour, depending on the area being scanned and the detail required. Patients may be asked to remain still during the scan, and some may experience a humming or knocking sound from the machine, for which earplugs or headphones are usually provided.
