MRImittauksissa

MRImittauksissa refers to Magnetic Resonance Imaging (MRI) measurements in Finnish. MRI is a medical imaging technique used to create detailed images of the body's internal structures. It utilizes a strong magnetic field and radio waves to generate signals that are then processed by a computer to produce cross-sectional images. Unlike X-rays or CT scans, MRI does not use ionizing radiation, making it a safe option for repeated examinations and for imaging sensitive tissues like the brain and spinal cord.

During an MRImittauksissa, the patient lies on a table that slides into a large, tube-shaped scanner. The magnetic field aligns the protons in the body's water molecules. Radio waves are then pulsed, causing these protons to emit signals. Different tissues emit signals of varying strengths and durations, which are detected by the MRI scanner. A contrast agent, often containing gadolinium, may be injected intravenously to enhance the visibility of certain structures or abnormalities, such as blood vessels or tumors.

MRImittauksissa are used to diagnose a wide range of conditions, including neurological disorders, musculoskeletal injuries, cancer, and cardiovascular diseases. The specific sequences and parameters used in an MRI examination are tailored to the clinical question and the area of the body being imaged. The process is generally painless, though some patients may experience claustrophobia due to the enclosed space of the scanner. Patients are typically asked to remain still during the scan, which can last anywhere from 15 minutes to over an hour, depending on the complexity of the examination.
