Monroe's Motivated Sequence: The Benefits Of X-rays
Specific purpose: My specific purpose is to inform you of the benefits of x-rays.
Audience outcome: I want my audience to feel less anxious about getting x-rays
Attention getter: Is everything hazardous to your health?
Psychological orientation: It can certainly seem that way if you watch the local news or read scary stories on the Internet. X-rays are yet another one of the benefits of science that many people fear because of the radiation X-ways can release.
Logical orientation: But you should be far more afraid of the risks of not getting X-rays when you need to have them as a result of a medical condition or to receive potentially beneficial screening. The ability of X-rays to pass through human tissue can be of great positive benefit whether you have a problem with a tooth, a broken bone, or any number of health-related needs. The risks of X-rays have been considerably overstated by those who fear the technology. So long as they are not used in excess and proper precautions are taken, there is nothing to fear (Attwood 1999).
Body
Transition: One antidote to this fear is knowledge: it is helpful and necessary to understand precisely what X-rays are.
Need step: Now I will address the need to understand x-rays
a. According to Mettler (2005) because X-rays have a long wavelength as compared to light, they are able to painlessly pass through human tissue.
b. Once the X-rays pass through the...
X-ways exhibit what is called a 'shadow gram' in which less dense soft tissue is contrasted with bone. X-rays can pass through soft tissues more easily than hard tissues (Mettler 2005).
d. This creates the classic black-and-white photographic appearance.
e. X-ray machines consist of X-ray ray tubes, lead shielding, and photographic plates to minimize risk. The X-ray tube is like a giant bulb that uses high voltage electricity; lead shielding is designed to direct the X- rays to the specific sections of the body being examined and prevent exposure to other areas.
f. The photographic plate captures images by the X-rays and the machine is as a whole is connected to a computer to allow a digital image to be produced. Sometimes the patient may be required to undergo more than one X-ray from a different angle.
g. X-rays can be used to detect breast cancer (through a procedure known as mammography); lung infections; bone fractures; infections; blocked vessels; enlarged hearts; bone cancer; fractures; dental decay; arthritis; osteoporosis; even foreign bodies and digestive issues. The information provided by X-rays can be potentially life-saving.
Transition: Now you understand how X-rays are done so they seem less frightening.
Satisfaction step: Now I will satisfy your curiosity about the alleged risks of x-rays
a. Although radiation is released by X-rays, according to Goldstone (2008), when used…

1. Screening Mammography Mammography plays a central part in early detection of breast cancers because it can show changes in the breast up to two years before a patient or physician can feel them. Current guidelines recommend a screening mammography every year for women, beginning at age 40. Research has shown that annual mammograms lead to early detection of breast cancers, when they are most curable and breast-conservation therapies are available (Mammography). 2.
D. (http://www.cancernews.com/data/Article/210.asp). The created a need to research and develop a better method of mammography, which lead to the development of the new digital machine. What is digital mammography? Conventional film screen mammography uses low energy x-rays that pass through a compressed breast during a mammography examination. The exiting x-rays are absorbed by film (x-ray film) which is then developed into a mammography image that can be held and looked at by the
Missed Breast Carcinomas Mammography is a particular type of imaging which use an x-ray system, which has a low-dose for the purpose of detecting breast cancer at a very early stage. But even with the help of Mammography, in 10-30% cases of breast cancers would be missed. By way of this paper an attempt has been made to understand the factors, which cause for missed breast cancers, and discuss ways to
Dr. Robb-Nicholson's data best supports the scenario that more incidents of breast cancer will be discovered due to the reduced number of screenings that the new guidelines suggest. According to the numbers she gives, the mortality rate for breast cancer decreases every year and this decrease can be attributed to the previous screening guidelines. She writes that the USPSTF has based the new guidelines on statistics rather than clinical data
Radiology and Cyberspace The creation of 'cyberspace,' or the sharing of information through email, on the Internet and on websites, has had a profound impact on nearly every field of human endeavor. Medical science, and particularly Radiology, has been particularly affected and enhanced by new technology. Radiology, by its very nature, has always been a leader in the use of emerging technology in the medical field. Now, new technology developed during
As a woman enters her geriatric years, many unique problems are also faced. Her post-menopausal period leaves a woman with increased risk of osteoporosis, and hormone-replacement therapy may need to be considered or dismissed depending upon the needs and wellness of the individual women. Additionally, increased risk for obesity begins nearly at the adolescent period, when women's hormone loads change and often activity of childhood decreases. The incidence of
