Watching the video clip Oprah’s Full Body Scan was so enticing that I wanted to get mine done just for curiosity. However, there are other tests that can obtain the same type of information which are noninvasive and less costly and covered by most insurance companies. For example, labs tests for cholesterol screening, vital signs monitor for early signs of hypertension, and physical examinations check for obesity. Listed on the National Cancer Institute website “most doctors recommend against whole-body CT for people without any signs or symptoms of disease” (CT-Scans-Fact-Sheet, n.d.).
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 the effective doses from diagnostic CT procedures are typically estimated to be in the range of 1 to 10 mSv. This range is not much less than the lowest doses of 5 to 20 mSv estimated to have been received by some of the Japanese survivors of the atomic bombs. These survivors, who are estimated to have experienced doses slightly larger than those encountered in CT, have demonstrated a small but increased radiation-related excess relative risk for

The careful familial and patient history is imperative for this exam and procedure. And as the video indicated, is this really an effective screening tool for a healthy person more so than seeing the primary care physician. According to the research in the Indian Journal of Medical Research, the “PET/CT doses were found to be higher than many other conventional diagnostic radiology examinations suggesting that all efforts should be made to clinically justify and carefully weigh the risk-benefit ratios prior to every 18FDG whole body PET/CT investigation” (Kaushik et al,
Oprah is one of the most well known and revered celebrities worldwide. What make Oprah distinct from mainstream celebrities is the entwining of the person and the product of Oprah. In each chapter, of Oprah: The Gospel of an Icon, Lofton compares materials from Oprah's many productions and religious culture. Lofton specifically focuses on the prosperity gospel as practiced by many churches and preached by Oprah, who gives gifts and fills pages of her magazine with products intended for a better life. Lofton also discusses celebrity culture and contemporary evangelism and how the brand Oprah thrives on the inseparable nature of religion and American capitalism
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.
Recently, new advances have been made in PET technology. A pair of American scientists working in Switzerland came up with a combination PET/CT scanner, which effectively pairs the two techniques. This new combination will be very useful in cancer diagnosis. With the PET/CT, both anatomical and functional imaging can be done and reproduced on the same image. This will be helpful in pinpointing the location of tumors, and also for the early identification of tumors too small to be of concern in CT scanning.
Oprah provides false interpretation in Their Eyes Were Watching God by transforming a vintage story into an altered tale. She changed many important aspects in Their Eyes Were Watching God by disregarding symbolic meanings, the characters portrayal, the relationships, and the entire theme of the story. Oprah deprived the story of it originality and left it with a copious amount of questions.
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...
In the radiology profession first you must write the patient’s file. This includes information about insurance, medical history, what the required x-ray is for and where it is going to be taken on the body. Writing in this way is similar to writing a small research paper. You must do research on the patients and there history and what insurance they have. Writing the report is important because the information must be accurate so the patient can be helped as much as possible. If the information about medical history is incorrect it can cause a huge problem for the patient. For example, if the patient is claustrophobic they would need to get an open room x-ray where the patient isn’t in an enclosed tube so they don’t have a panic attack and potentially injure themselves and others. It is very important to make sure the report has the correct area of where the x-ray needs to be taken. Having the wrong part of the body x-...
Driver, (2013), described the DEXA scanner as a machine that produces two x-ray beams of high and low energy levels. Much like fluoroscopy, the x-ray from the DEXA scanner comes from underneath the patient, and the scanner has a very low x-ray dose. Earlier versions of the DEXA scanner emitted radiation which required up to five minutes to scan an area of interest, but the more advanced machines can take as ...
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.
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...

Many of the experts agree that the dose should be kept as low as possible with minimal exposure to the fetus of any age. It has been shown that fetuses before 16 weeks are the most sensitive to any dose of ionizing radiation and have been shown to have lower IQ’s and verbal scores than those exposed after 16 weeks. Fetuses exposed after 16 weeks have the same amount of risk as children up to 10 years old getting cancer. It is very important to take in to consideration gestational age, shielding, the position of the x-ray tube and the amount of necessity that is considered in taking a radiographic image or performing a radiographic procedure in a pregnant woman.
Many people think if they do not feel any lumps in their breasts there is nothing to worry about. That is not always the case. “Mammography remains the “golden standard” screening method for women…and reliably identifies malignant tumors, especially those that are too small to feel (“Advances in breast imaging”). “Checking one’s own breasts for lumps or other unusual changes is called a breast self-exam, or BSE. This type of exam cannot replace regular screening mammograms or clinical breast exams. In clinical trials, BSE alone was not found to help reduce the number of deaths from breast cancer (cancer.gov)”. Mammograms are necessary because performing a self-exam does not always find what is there. Although self-breast exams have been known to catch lumps in the breast, mammograms have found more due to the fact that they can detect very small cancer much sooner than self-breast exams can. Also not very many people know how to correctly administer a self-breast exam. It is recommended that if you do perform self-exams you should also get routine mammograms. If you rely solely on self-exams, it may be too la...
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.
