MRI Procedure
The procedure of an MRI is used for imaging diagnostics and is based on the application of a magnetic field. This causes certain particles in the body to be aligned with the magnetic field. If the magnetic field is switched off, the particles reorient themselves in their original position and the respective speed to reach the position is measured.
Since this velocity is different for all particles, images can be generated from the measured data. No rays are used here as in X-rays or CT. During an MRI, sectional images of the head are produced, which allow different structures to be assessed very accurately. An MRI of the head can show the brain, the skull, the blood vessels, the cerebral ventricles (ventricles) filled with cerebrospinal fluid (liquor) and the other soft tissues of the skull.
