Magnetic Resonance Imaging And The Health Field

Medical imaging is used to create visual images of the interior part of the body so that it would be easier to examine, diagnose & treat patients without the need of surgical processes. This process is used to see what is beneath the skins and bones to find any abnormalities present.

It was seen that the radiologic Technicians earned a median wage of $54,340 annually and the middle 80% of technicians surveyed earned between $36,510 and $76, 850. The prospective job pays off a hefty salary and the level can vary based on the individual qualifications and specific responsibilities of the job of an MRI technician.

An MRI uses computer-generated radio waves and a strong magnetic field to produce a detailed image of the brain. “MRIs are helpful in the diagnosis of tumors, eye diseases, infections, inflammation, and damage due to head injury” (Hill 2008). When getting an MRI, you lay on a table that slides into a tube, and they use computer-generated radio waves and a very strong magnetic field to see images of the brain. This test will allow the doctor to see two and three-dimensional images of your brain.

The prices can vary greatly state to state. Unfortunately, it falls on the patient if it is a scheduled exam to “shop around” to get the best price available to them. Just like the MRI machines, these scanners can run anywhere from $65,000 to 2.5 million dollars. Where CT excels over MRI, is the fact that anyone who has metal in their body that is not removable, can have this scan with no issue. The scan itself is faster, for the patients who may be claustrophobic, this gives them some peace of mind. It also does not produce the loud banging noises that the MRI gives off. The only real contraindication would be any contrast allergies. CT can still be performed without contrast, but the areas of interest won’t be highlighted as well. A typical scan takes about fifteen to thirty minutes, depending on what anatomy is being looked at.

Magnetic Resonance Imaging (MRI) is a way of medically imaging the body with the use of a magnetic field and radiofrequency waves. (1) As image quality of MRI continues to improve, more MRI exams are being ordered. Increasing MRI exams leads to increased wait times. Due to current wait lists, the health status of patients may decrease, influencing the type of treatment the patient will require once removed from the wait list. (7) The advances in technology have increased in the past decade, with MRI procedures are vastly growing to provide superior diagnostic quality compared to other modalities. New technologies are also allowing for faster scan times and further increased image quality. (9)

Raymond Damadian is the man behind the MRI, he is the one who created it. His idea sparked from a machine called NMR, which is short for Nuclear Magnetic Resonance. An NMR “Scans salt loving bacteria called halophytes that contain twenty times greater potassium levels than most bacteria. Results were so promising that Damadian realized the technique could be used to diagnose cancer and other diseases in humans.” (Raymond Damadian, Inventor of the MRI). Raymond’s wife said that he struggled at times to create the machine, but he kept his faith, and kept working, and now the MRI provides answers to people who thought there never was one. Damadian was a strong Christian and gave all the glory to God.

“This MRI machine, or magnetic resonance imaging machine, is the most advanced and safest way to produce a magnetic image of the human body. Strong magnetic waves align the patients hydrogen atoms within the bodily tissues and cause them to vibrate and point in the same direction. Radio wave frequencies then disturb the hydrogen atoms so that they return to their natural randomized order. The imaging part of the machine then records and translates the data onto this screen here so that we are able to examine the patient’s brain, spine, soft tissues,and joints, which are the most common uses for an MRI (Sternlof). Why are we able to determine where the cancer or the tumor is by the image that is produced?” I asked. I was curious if anyone was slightly familiar with the information I had been talking about. A tall, brown haired man in the back of the

MRI: Magnetic Resonance Imaging... involves creating a magnetic field around a person 's body and using radio waves to construct imagines of the person 's tissues and biochemical activities.

Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan. MRI also may show problems that cannot be seen with other imaging methods.

Magnetic Resonance Imaging machines, more commonly known as the MRI, are a very popular tool in the medical field because it is painless and it does not use ionizing radiation; which can produce terrible side effects and can even damage your organs.

Magnetic resonance imaging (MRI) is a test that lets your health care provider see detailed pictures of the inside of your body without using X-rays. Instead, strong magnets and radio waves work together in a magnetic field to form very detailed and sharp images. The images are viewed on a TV monitor in two- and three-dimensional form. The magnets and radio waves are harmless.

Magnetic Resonance Imaging is also known as MRI. This computerized device is used for scanning the

Magnetic resonance imaging has the potential of totally replacing computed tomography. If history was rewritten, and CT invented after MRI, nobody would bother to pursue CT. --Philip Drew (Mattson and Simon, 1996)

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.

MRI technology is a useful technique in the medical industry, there are many advantages to its use and for the most part the disadvantages of its use are minimal. They are great because they provide very detailed diagnostic pictures of most of the important organs and tissues in one’s body. They are also capable of showing unique information that other tests are unable to show. They are generally painless. Furthermore, they do not use radiation and are therefore suitable for use in children and pregnant women. Although there are many good attributes to MRI’s, there are still disadvantages to its use. For one, many people are claustrophobic and being in an MRI can become very uncomfortable for them. In addition, the MRI makes a tremendous amount of noise. Often patients are given earplugs or stereo headphones in attempt to muffle the noise.
