What's an MRI

What's an MRI!!?

Magnetic resonance imaging (MRI) is an examination that provides two- or three-dimensional views of the body's interior. MRI provides information about lesions that are not visible on standard x-rays, ultrasound or CT scans. 


Magnetic resonance imaging uses a magnetic field (magnet) and radio waves. No ionizing radiation is emitted.



Its principle consists in creating images of the human body thanks to the many hydrogen atoms it contains. Placed in a strong magnetic field, all hydrogen atoms move in the same direction: they are then excited by radio waves for a very short period of time (they are put in resonance). When this stimulation stops, the atoms release the accumulated energy by producing a signal that is recorded and processed as an image by a computer system.



The machine consists of a tunnel formed by a magnet inside which the examination bed will enter as well as antennas adapted to the region to be explored.
    The control panel behind which the medical personnel are located, which is separated from the machine by a protective glass.

 MRI studies with great precision many organs such as the brain, spine, joints and soft tissues. It is very useful when a very detailed analysis is required and some lesions are not visible on standard radiographs, ultrasound or scanner. It allows to make cross-sectional images in different planes and to reconstruct in three dimensions the analyzed structure.
