How the MRI Procedure has an Impact on Society

The introduction of Magnetic Resonance Imaging several years ago has a tremendous effect on our society today. This procedure enables physicians to diagnose and possibly cure several diseases which could otherwise prove to be fatal. As for anything in our society, there are some people who will criticize and find the negative points to it, however the positive impact that MRI scanning has on our society definitely outweigh any negatives.

How the MRI Procedure has an Impact on Society
Since the introduction of Magnetic Resonance Imaging, better known as the MRI scan, medical technology has taken a huge step forward in assisting the diagnosis of sometimes fatal diseases. This in turn has a tremendous impact on our society today; it gives medical professionals an advantage in diagnosing and treating diseases in the earlier stages. Without such tests as the MRI, many lives may be lost that could have otherwise been saved. While the advantages are great, as with any test, there are some disadvantages as well. Overall, the advantages greatly outweigh the disadvantages. The MRI is another step towards equipping health care professionals with ways to treat and cure the people of the world who become ill or injured. Dr. Raymond Damadian, a physician and scientist, experimented for some time attempting to produce a machine that could scan the body with the use of magnets. Along with some graduate students, he constructed a magnetic device that he hoped would produce an image of inside the human body. Since no one wanted to be the first one in this apparatus, Damadian volunteered to be the first patient. When he climbed into the device, nothing happened; Damadian was looking at years wasted on a failed invention, but one of his colleagues bravely suggested that he might be a bit large for the machine. A graduate student volunteered to give it a try, and on July 3, 1977, the first MRI exam was successfully performed on a human being. It took almost five hours to produce one image, and that original machine, nick-named the "Indomitable," is now owned by the Smithsonian Institution. Not long after, the first magnetic resonance imaging scanners for human use became available, able to produce images of the inside of the body. Current MRI scanners are capable of producing precisely detailed 2-dimensional and 3-dimensional images of the human anatomy. In just a few decades, the use of magnetic resonance imaging (MRI) scanners has grown exceedingly. Physicians may order MRI scans to help diagnose such things as multiple sclerosis, brain tumors, torn ligaments, tendonitis and cancer and strokes. An MRI scan is the best way to actually see inside of the human body without cutting it open. The MRI scanner is a complex device; it can see things that other diagnostic equipment such as x-rays and CT scans cannot. According to Dr. Lawrence M. Davis (2009) the basic process of an MRI is as follows: * An MRI is similar to a computerized topography (CT) scanner in that it produces cross-sectional images of the body. Looking at images of the body in cross section can be compared to looking at the inside of a loaf of bread by slicing it. Unlike a CT scan, MRI does not use x-rays. Instead, it uses a strong magnetic field and radio waves to produce very clear and detailed computerized images of the inside of the body. MRI is commonly used to examine the brain, spine, joints, abdomen, and pelvis. A special kind of MRI exam, called magnetic resonance angiography (MRA), examines the blood vessels. * A MRI scan can be used in order to view all parts of the human body, including bones and tissue. Some of examples of how the scans are very helpful to our society include a MRI of the brain, which produces in depth images of the brain and is commonly used with...
