...Understanding The Hazards Of The MRI Technique Magnetic resonance imaging (MRI) is one the most rapidly advancing imaging techniques available today. Not to mention one of the safest but there are many safety precautions that need to be taken before encountering its magnetic field. It is used to produce detailed sectional images of the body on any imaging plane. Compared to the x-ray medical diagnostic techniques, general position emission tomography (PET) and computed tomography (CT) a (MRI) scan does not apply ionising radiation but uses the radiofrequency field to scan the body. Therefore, the system is considered to have less health effects than the ionising radiation-based imaging modalities. The potential benefits of MRI are numerous,...

...National Institutes of Health, University of Washington School of Medicine is ranked number five out of all the medical schools in the country (National Institutes of Health). My love for Radiology started in 2014 when in the middle of my level 8 gymnastics season my back started hurting. I went into the Idaho Sports Medicine Institute at Boise State where they took a x-ray of my back. As they showed the picture of the x-ray to my mom and I of my stress fracture I thought it was the coolest thing in the world. From then on, I felt that being a Radiologist was just perfect for me. While it takes a little more extra education than other jobs it would definitely be worth it. “Choose a job you love, and you will never have to work a day in your life” (Confucius). Radiology is so interesting and with all the love I have towards it I wouldn’t ever have to work. A Radiologist is a doctor who interprets x-rays and other medical images, they can also treat disease with radiation. Along with their main job of interpreting medical images, they also look over radiologic technicians to make sure their pictures are the best quality possible and that they’re being safe. A doctor can also specialize in only one area of medical imaging if they choose, including; cardiovascular which is heart and lungs, musculoskeletal which includes the muscle and bones, or just plain body imaging. A Radiologist has a lot of activities they do on a regular basis, Idaho Department of Labor states that they: ...

...Medical Imaging is a vital part of today’s medical industry as technology and the understanding of nuclear medicine has been able further provide diagnosis for thousands of diseases and injuries. The beginning of medical imaging occurred in 1895 when the first ever x-ray was taken by German Physics Professor, Wilhelm Conrad Roentgen (Imaginis, 2008). Since then the expanded knowledge of the atomic nucleus and discovery of radioactive isotopes have expanded the ability enabling us to image soft tissue, inflammation, abnormal growths and circulation. The atomic nucleus is essentially the number of electrons, protons and neutrons within an atom which determines the characteristics of the element. Within the atom, strong nuclear forces hold the neutrons and protons inside the nucleus, preventing the atom from breaking apart which provides stability for the smaller elements, such as oxygen and carbon (J. Lucas, 2014). To produce stability for heavier elements, the ratio of neutrons to protons must increase as the repulsion forces between the protons increase. This increase in neutrons decreases the space between the protons and prevents the repulsion forces from overcoming the strong nuclear forces. Isotopes are identified by the varying number of neutrons within the nucleus (Khan, 2014)...

...Brief History of Medical Imaging Medical imaging has played a very significant role in medicine for over the last one hundred years. It is one of the most important diagnostic tools available to doctors and has revolutionized the medical diagnosis of patients. The use of medical imaging has enabled doctors to see inside a patient without having to cut them open. Medical imaging, especially X-ray examinations and sonography which is also known to some as ultrasound, is essential in an everyday medical setting. Preventive medicine as well as healing medicine depends on the proper diagnosis and treatment by physicians, and the use of diagnostic imaging can help evaluate the course of a disease, as well as assess and document the disease in response to the treatment. Medical imaging has rapidly expanded from the first medical image discovered by Professor Wilhelm Conrad Roentgen. During a late night experiment in November of 1895, Roentgen, a physics professor from Germany, was examining Crookes tubes. He noticed that some light had managed to pass through a tube that he had wrapped in thin black cardboard, reflecting on the wall of his dark laboratory. Upon further investigation he found that the light could also be passed through paper, books, and eventually through human flesh. Unintentionally, he had stumbled upon a very important discovery that led to the discovery of what we now call an X-ray. One of the very first x-rays was one...

...Health Informatics Preparing a patient for a diagnostic technology – Head CT Scan Throughout history, man has striven to explain poor-health and illness. It was originally thought that disease stemmed from being possessed by evil spirits and other supernatural causes. However, these concepts were rejected by the Greek physician Hippocrates around 400 BC in favour of disease having a physical, rational and therefore measurable cause, (Porter, 1994). Yet it was not until 1895 that Wilhelm Conrad Röntgen discovered x-rays and began to revolutionise the assessment process using non-invasive techniques. (Nobel Lectures, 2012). Since then, many types of diagnostic imaging techniques have been discovered and developed which play an integral role in modern medicine. These include Ultrasounds, Magnetic Resonance Imaging, (MRI), Electrocardiograms (ECG) and Electroencephalography, (EEG). This essay will discuss; the rationale of referring a patient for Computerised-Tomography, (CT) scans; the support given throughout the process; evaluation of the benefits and risks of the technique and resulting diagnosis. A 28 year old male was brought into hospital by emergency ambulance after being involved in a motor-cycle accident. He had sustained multiple fractures and a dislocated shoulder.

In my occupation as a radiology technologist at Bassett Army Community Hospital, I am one of several soldiers who perform computed tomography (CT) scans for active duty soldiers, their family members, retirees and other beneficiaries within our footprint. Perform CT scans is an exciting and rewarding career path, and one that I am proud to be a part of. In this piece I will briefly discuss what this particular technology does and how it works, as well as delve into some of the benefits and disadvantages of CT scans. CT is an interesting technology in terms of what it can be utilized for and how exactly it works. The technology used today owes it’s existence to the discovery of x-rays in 1895 by Mr. Wilhelm Roentgen. X-rays are a form of ionizing radiation. This type of radiation refers to the process by which an atom is excited, or energized to the point that outer layer electrons are expelled or “boiled” off. In CT, these electrons are directed towards a patient for the use of forming either a two or in some cases, three dimension image of the internal anatomical structures of the patient. The specific concept of how a CT image is formed can be difficult to both explain and...

...with an adequate supply of quality services that enhance the health and well-being of those seeking care. The value of a new medical technology is determined by supply and demand (Getzen, 2007). Diagnostic radiology is a prime example of the value being determined by both supply and demand. As radiologic imaging advanced from two dimensional x-ray images to three dimensional ultrasound images, magnetic resonance imaging (MRI), and Computed tomography (CT) providing better image quality and increased accuracy of diagnoses, the demand for these services rose. Statistics show that from 1996 to 2006 the frequency of radiology imaging increased nearly 60%, from 61 million studies to 99 million (Klein, 2008). This significant increase in use is directly related to enhance image quality used for diagnosis. This figure will continue to rise as more baby-boomers use these services to diagnose potential health issues that can be determined through radiologic imaging. This paper will discuss the demand and supply of outpatient radiologic imaging centers within the United States health care industry. Outpatient Radiologic Imaging Statistics indicate the growing use of radiologic imaging for diagnosis of health ailments. This demand has created a strain on the ability of hospitals to adequately supply all patients with access to diagnostic radiologic imaging without delay. This...

...Jennifer Boice Charles Dold ENG-0900-83053 30 October, 2010 Work/Career Essay-Radiologists Salaries Radiology is a field of medicine that uses medical imaging techniques to assess patient conditions and administer treatment. To become a radiologist, one must complete a great deal of schooling, but the job rewards, both personal and financial, may be well worth it. Radiology techs are not only high in demand in most communities, but also highly paid relative to other allied health professionals. As with any job, there are many variables that will determine how much money people can expect to see not only at the start of their job, but throughout their entire career. The amount of schooling, experience, and location are the three main variables that will determine annual salaries. The amount of schooling is one of the important variables needed to raise ones yearly salary. This includes whether or not graduates received their education from an accredited school, along with what kind of degree or certification earned. Most radiologists will need the standard four years of undergraduate study, followed by medical school and residency. In most cases, radiologists must be board certified, which means taking and passing an exam to earn approval to practice from the American Board of Radiology or other governing bodies. Not only does schooling have an affect on ones salary, experience does as well. The experience a student has is the second important variable....

...EXECUTIVE SUMMARY Quinte MRI, Inc. was a small, but growing, international service provider specializing in a variety of medical technologies including MRI. Quinte MRI’s founder, Dr. Syed Haider firmly believed that the residents of smaller communities deserved the same level of health services as the residents of the larger urban centers. Haider’s first attempt to establish a facility such as this was unsuccessful due to Canadian regulations prohibiting private-sector MRI. MRI had become increasingly popular, by 2001 there were 18 million MRI procedures performed in the United States. Dr. Syed Haider have appointed David Wright and Kevin Saskiw to address this problem pertaining to the MRI facility and only gave them two days to make recommendations and provide a detailed action plan. As David Wright and Kevin Saskiw, I propose making the necessary adjustments to address the backlog of MRI scans and better manage the bottleneck of the process. The MRI clinic is experiencing problems; the relationship between BCMC and Quinte MRI is in trouble because promised expectations of 2 scans per hour is not met, performance is reduced , productivity is declining and they are at risk of losing their competitive edge. Balancing the process flow will make the operation more effective and manageable. With the process the way it is there are a lot of variability and uncertainties that I will have to contend with. By better managing the scheduling process I will definitely reduce wait...
