magnetoresonantsuuringuid

Magnetoresonantsuuringuid, often abbreviated as MRI, is a non-invasive medical imaging technique that utilizes a strong magnetic field and radio waves to produce detailed images of the internal structures of the body. Unlike X-rays or CT scans, MRI does not use ionizing radiation, making it a safer option for repeated examinations and for imaging sensitive tissues like the brain and spinal cord.

The process begins by placing the patient inside a large, powerful magnet. This magnetic field aligns the protons within the water molecules of the body. Radiofrequency pulses are then applied, which temporarily knock these aligned protons out of equilibrium. As the protons realign themselves with the magnetic field, they emit radio signals that are detected by a receiver. Different tissues emit signals of varying strengths and decay rates, which are then processed by a computer to create cross-sectional images.

MRI is employed to diagnose a wide range of conditions affecting organs, soft tissues, bone, and virtually all other internal body structures. It is particularly valuable for visualizing abnormalities in the brain, spinal cord, joints, muscles, and heart. The ability to differentiate between various types of soft tissues is a key advantage of MRI, enabling the detection of tumors, inflammation, injuries, and degenerative diseases. The procedure is generally painless, though some patients may experience claustrophobia within the MRI scanner.
