MRI Magnetic resonance imaging uses magnetic field and radio wave energy to diagnose and capture images of the organs and the structures inside the body. It is a test which uses nuclear magnetic resonance in order to take pictures which can then be used to diagnose problems for instance injury, blood vessel disease, tumors and the like. A highly unique method, it's known for diagnosing problems which cannot be found with other imaging methods. Usually, an MRI is carried out to add on to the information already provided by the ultrasound, X-ray, or the CT scan, so as to give a clear cross-section view of the problem. To perform an MRI test, the patient has to be placed inside a special hallow machine which contains a strong nuclear electromagnet. The electromagnet then becomes active, causing the nuclei of atoms to align magnetically. The aligned nucleus changes its position shortly...

The receiver detects the radio waves which is then comprehended and translated by a computer on to a two dimensional picture, which are later usually interpreted by a radiologist. The MRI test takes approximately half an hour to be carried out and could go on for about two hours at the most. It is a must for the patient to remove most of the clothes worn at the time of scan and any metal objects worn also since metal may become powerfully attracted to the magnet being used. (2009)
An MRI scan can be taken for various body parts including the head, chest, blood vessels, and bones and so on. To help remain still, it may be necessary to strap the patients head, chest and arms inside the MRI magnet. Because of this, some patients may feel claustrophobic. The patient can be given sedative to help feel relaxed. Overall, the…
