Magnetic resonance imaging (MRI) is an imaging technique that uses high-frequency wave magnetic fields. Discovered in 1980, it is mainly used for the study of soft tissues, such as brain structures and spinal cord, abdominal parenchymatous organs and the musculoskeletal system.
It is a multi-planar investigation technique that acquires images directly on the axial, coronal or frontal plane. The images obtained are a function of the structure and of the molecules that make up the different organs and body systems, with an extremely high contrast resolution that makes it possible to differentiate, in the context of soft tissues, structurally different anatomical formations, such as muscle, tendon, cartilage, effusion and adipose tissue.
