Humanity, constantly learning, growing, and facing more challenges each second of the day. Whether the challenges are mental or purely physical, we have found more efficient, safer, and easier ways of doing the tasks we may face. From moving cargo to sending information via the Internet. Probably the greatest accomplishments we have made, are in the studies of medicine/treatment; to be specific, the study of radiology. Radiology is the process of working and viewing inside the human body without breaking the skin. By using radiant energy, which may take the form of x-rays or other types of radiation, we are able to diagnose and treat many diseases and injuries. Both diagnostic and therapeutic radiology involve the use of …show more content…
Last of the diagnostic imaging tools is the MRI. MRI, which stands for Magnetic Resonance Imaging, was a technique developed in the 1950?s by Felix Bloch, and is the most versatile, powerful, and sensitive tool in use. The process of MRI was originally called NRI, Nuclear Resonance Imaging, but was found to be to confusing due to the fact that MRI?s don?t use radioactivity and ionizing radiation. The MRI generates a very powerful electromagnetic field, which allows the radiologist to generate thin-section images of any part of the body. Also it can take these images from any direction or angle, and is done without and surgical invasion. Another plus side to the MRI is the time it takes to perform, where as a CAT scan may take 30-60 min. A MRI may only take 15 minutes max. The MRI also creates ?maps? of biochemical compounds within a cross-section of the body. These maps give basic biomedical and anatomical information that provides new knowledge and may allow early diagnosis of many diseases. The MRI is possible in the human body because our bodies are filled with small biological ?magnets?, the most abundant and responsive of these are the protons. The principal of the MRI is that it utilizes the random distribution of protons, which have basic magnetic properties. Once the patient is placed in the cylindrical magnet, the diagnosis process follows 3 steps. First, MRI
