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
The rate of absorption in the body is measure in megahertz and gigahertz ranges. Then MRI stimulates the body with radio waves to change the steady-state orientation of the hydrogen protons. It then Stops the radio waves and ?listens? to the bodies electromagnetic transmissions at the selected frequency. The transmitted signal is used to create images much like those of the CAT scans, but are far more accurate and much easier to interpret. In current practice, the MRI is preferred for diagnosing most diseases of the brain and central nervous system. And is the best diagnostic technique we know. Its? images, information, and other vital information surpass that of its? relatives; the CAT scans, x-rays, PET scans, etc. The MRI has yet another distinguishing feature it can determine between soft tissue in both normal and diseased states. The only drawback to the MRI is that it is relatively expensive, but that may not be so bad when you account for all the money and time you save by getting treatment and diagnosis sooner. Because the MRI uses no radiation what-so-ever the only risk it presents is to people who have known metal fragments in head, eye, or body. Many organs that may not be visible by routine radiographic methods may become visible by ingesting, installing, injecting, or inhalation of substances. These substances are called contrast media, which are impenetrable by radiation. Exams involving a contrast include the upper intestine,
