In today’s society, it’s much easier to detect and diagnose an illness because of a great medical detection technology: Computed tomography scanning or CT scans. It’s a scanning technology which uses X-ray computed tomography to generate images of internal organs in human body. Because of its accuracy, more and more people choose to use CT scans. According to Bernier and his team’s research (2015), in the USA, “the number of CT scans increased from 2 million in 1980 to about 70 million in 2007” (p116) and this number is still growing. But in fact, CT scanning technology is credited to the use of the X-ray, oddly enough, it’s also criticized due to the X-ray. The reason is “the radiation used in CT scans can damage body cells, including DNA molecules, which can …show more content…
Since the source of cancer is from radiation so it’s obvious the more radiation you take will rise more risks. I’ve mentioned that we are already limit CT scan’s radiation doses. But there is some certain situations need people to do multiple CT scans. Furthermore, “the radiation doses received from CT scans are 100 to 1,000 times higher than conventional X-rays” (Rita 2014). Some of us are actually taking more doses than the normal level.
Overall, most researchers believe there is an increasing in rate of cancer if a person take too much doses or take scans at young age. There are some other ways to diagnoses illness without using CT scans.
Since the possible risk of using CT scans, people should avoid using it unless use of CT is necessary. Without CT scans, there are other non-irradiated alternatives such as ultrasound tomography and MRI tomography can do the work. Both of ultrasound and MRI are widely used in diagnostics. Patients will not be exposure to radiation when to use either of them. MRI scans use radio waves and strong magnets to produce images and ultrasounds use high-frequency sound waves to produce
What needs to be assessed is how these full body scans are produced. It is produced through radiation through computed tomography. And, is the amount of radiation that a patient is receiving necessary. Radiation exposure is harmful. According to the FDA website
As an ultrasound technician/sonographer I will have the ability to see dangerous defects within the human anatomy and begin a lifelong profession with many benefits. The Ultrasound was first invented in the early 1900’s and was surprisingly not used to produce photos of a fetus. In 1917 Paul Langen a marine life scientist used a form of ultrasound equipment in his attempt to detect submarines. After many failed attempts at using high frequency sound waves Dr. Ian Donald and his team in Glasgow, Scotland invented the first ultrasound machine in 1957. Dr. Donald even tested his machine on patients within a year of completing the invention, by the late 1950’s ultrasounds became routine in Glasgow hospitals.
The dream that I most desire in life is to become a Diagnostic Medical Sonographer. I’ve always had an interest in the inner workings of the human body, but I also value life, and care for others, and my happiness is the happiness of others. Although this career has its bumps on the road just to see mothers face light up when they see the image of their unborn baby is such a breath taking experience. This all originated from going to one of my sisters’ ultrasound appointment that I ended up going to all my sisters’ ultrasound appointments. I believe becoming a diagnostic medical sonographer is something I can do because I have what it takes. Diagnostic medical sonographer is imaging modality that can work in conjunction with other imaging modalities
The MRI, on the other hand is less expensive and much safer (as it doesn’t expose the patient to potentially harmful radioactive chemicals). The MRI or magnetic resonance imaging device, as an safer alternative, applies a powerful magnetic field around the head of the patient.
Do diagnostic Medical Sonographers actually help begin a new life? Yes, according to researchers they do help patients indicate any problems that there may be and what may be expected. This essay will talk about Diagnostic Medical Sonographers and everything it takes to become one and how to become successful as well as why they are important to our global community. Sonographer’s are also known as ultrasound Technicians, they are very important in the medical field because they help patients and physicians diagnose and treat diseases as well as other medical information. The following paragraphs will talk about the information of the Salary and also the Job Responsibilities. With the technicians continuously providing
Welch’s instructions were to be followed, the state of medical care in the United States would reflect exactly what his titles states: less medicine, more health. Welch explains that currently, the central problem with the medical care system in this country is that too much money is being invested on health care that does not reimburse an equal measure of health. Medical care holds too little value, with too much money currently being invested in a healthcare system that over-diagnoses patients, and does not prioritize overall health and wellbeing. This needs to change. As Welch explains with the story of two CT scanners in the Boulder community—this was a situation that would allow for more CT scans to be performed, and more being money to be spent on these scans. This example demonstrates that if Dr. Welchs’ instructions of improving health and lessening the medicalization of health were followed, there would be a balance between wasteful and harmful
Ultrasound Technicians are very valuable in the world of health care. Also known as Diagnostic Medical Sonographer, an Ultrasound Technician uses special machines and equipment that operates on sound waves to determine or diagnose medical problems for patients. There are specializations within this field in which some individuals explore. For instance, areas of specialization includes but not limited to; pregnancy, heart health, gynecology, and abdominal sonography. Although each specializing branch has its own distinctive function, they all involve probing the body to facilitate doctors with diagnoses.

The maximum recommended radiation doses in pregnancy are 50 mGy [Stovall, 1995 #6]. A CT has a dose of _________ which is well below the max recommended. A MRI is a preferable mode of assessment and even when contrast has been used it has not been associated with any teratogenic effect. CT scans may be more widely available and a diagnosis in a suspected case should not be delayed because...
All in all, MRI is a great imaging modality to properly diagnose a patient. MRI has many advantages and does not use any type of radiation. Even though MRI has been around for about a century it has gained a lot of advancement in the image quality. MRI allows a wide variety of anatomy to be imaged such as soft tissue, spine work, and organs. Like any imaging modality MRI does have a couple of disadvantages, but the advantages out way the risks. MRI will continue to improve and will be one of the best imaging modalities in the medical field.
For decades, the effects of radiation has been studied by doctors around the world. X-rays are used in the medical and dental field to take radiographs of certain parts of a person's body. Some have become concerned of the long term and short term effects of having x-rays taken because of the radiation that is exposed. Since the rise of concern, studies have been done to find any type of link between cancer and radiation from x-rays. Specifically, in dental x-rays, researchers have been performing studies trying to prove that radiation from x-rays in the dental office can cause cancer .
As a starting point in CT diagnostic imaging the form of radiation used to provide an image are x-rays photons , this can also be called an external radiation dose which detect a pathological condition of an organ or tissue and therefore it is more organ specific. However the physics process can be described as the radiation passes through the body it is received by a detector and then integrated by a computer to obtain a cross-sectional image (axial). In this case the ability of a CT scanner is to create only axial two dimensional images using a mathematical algorithm for image reconstruction. In contrast in RNI the main property for producing a diagnostic image involves the administration of small amounts of radiotracers or usually called radiopharmaceutical drugs to the patient by injection or oral. Radio meaning the emitted of gamma rays and pharmaceutical represents the compound to which a nuclide is bounded or attached. Unlike CT has the ability to give information about the physiological function of a body system. The radiopharmaceutical often referred to as a nuclide has the ability to emit ga...
There are ways to better understand how radiation affects the body when compared to other every day activities. If an occupational worker receives 1 rem per year then is it possible that 51 days is expected to be lost. A person that smokes 20 cigarettes a day takes about 6 years off of their life. People that are overweight by 15% take about 2 years off of their life. In actuality radiation would seem as though it is not any more harmful than other everyday activities people decide to do such as smoke, chew tobacco, or sky dive. The risk of taking days, weeks, years off of ones lives will always be present depending on the activity they choose to be part of. However, radiation exposure in the healthcare field is used to extend the patient’s life by helping them find out what is going on in their body. A patient that comes in with RLQ pain, nausea, and vomiting then an abdomen x-r...
Although no adverse health effects have been directly linked to low-dose radiation exposure, the medical community is playing it safe with regards to radiation. Most physicians are very careful about ordering radiologic tests. They should not order a study unless it will improve patient care. If you have a question about the importance or the necessity of a radiologic test that has been ordered for you, be sure to ask your physician.
I chose this topic because I a found it as a very interesting thing which I wanted to know more about. I have been CT-scanned when I had concussion after a car accident when I was seven. Also because my father has been under a CT-scanner and a lot of my friends.
