MRI stands for magnetic resonance imaging, and it is a diagnostic medical imaging process used in radiology to view the physiology and the anatomy of the human body at various locations. MRI scanners utilize extremely strong magnetic fields, strong radio waves, and carefully generated images of the structures in the human body to produce detailed images of those structures. MRI may be used to create a map of your heart's activity around your neck, or it may be used to create an image of your brain's fluid flow in your brain. These imaging techniques allow radiologists to track and diagnose various conditions in the human body that would be otherwise difficult to identify, sometimes with dangerous consequences.

MRI stands for magnetic resonance imaging, and this procedure has rapidly advanced through the use of powerful magnetic fields and computer systems to create highly accurate images of the human body. The MRI procedure is done on a lab bench and the equipment itself consists of several large-scale MRIs: one for each of several areas of your body, and one larger image. In order to obtain the maps of your blood vessels or cranial arteries or even the internal structures inside the human skull, the MRI technicians use the proper and specially adjusted imaging equipment, the most commonly used of which is a machine called a magnetron. This powerful magnet provides the electricity necessary to produce the images by forcing excited particles into a highly excited state, which is exactly what the MRI scanners do when they scan the area being scanned.

You may have heard about an "MRE" (Medical Resonance Imaging) or "umbo" (um Medical Resonance Imaging) as you may have seen them on TV, in movies, or from medical literature. An MRI exam can also be performed by a doctor who is not a trained or licensed medical professional. Although the equipment and procedures used in an MRI are much more sophisticated than what you may be used to viewing in a hospital, the average patient should expect to feel the same kind of discomfort that you would experience if you were lying in bed with a thick blanket wrapped around you, with tubes sticking out of your head and attached to your body by flexible plastic tubing or cloth. Nevertheless, although MRI technology has advanced greatly over the years, your doctor should explain the procedures to you fully and make sure you understand exactly what an MRI machine is and how it works before proceeding.
