MRI is known as magnetic resonance imaging. It is a non-invasive diagnostic method that employs radio waves rather than x-rays to form the images. This procedure is specifically valuable for imaging of soft tissues such as the spinal cord, brain, muscles and that of ligaments and also detecting abnormal tissues like tumours.
How does MRI works?
MRI procedure uses a scanner that is a cylindrical machine. It is used to get images of the human body. An MRI machine is made up of a round tunnel or bore inside which the patient or individual lies on a narrow table. Surrounding the tube is a massive cylindrical magnet. During the duration of an MRI scan, the patient is inside a stable magnetic field that is actually ten thousand to thirty thousand times stronger than the magnetic field of the earth. Since it is a non-invasive procedure you are not going to have any pain or ache. You can look for MRI scan centers in Chennai for your scanning.

These echoes are established by the MRI scanner, and are then rebuilt into pictures of the body by a computer. The pictures are extremely precise and give a clear anatomical view of the body from all the angles.
