Week+Three+Case+Study

OK, this week you guys find the medical chart and repeat the assignment as last week. The case study should be one that relates to the Chapter of the week: Chapter 20 Radiology and Diagnostic Imaging. Find a chart on the internt (please include link) and then make some typos that are medical words. Then your class mate will correct it. Go for it! Due April 21.

**Mammography** is a breast screening procedure. The process of using low-dose amplitude-X-rays (usually around 0.7 micro sievert dose equivalent) to examine the human breast (disambiguation) is used as a diagnostic as well as a screening tool. The goal of mammography is the early detection of milk duct or lobule cancer, typically through detection of characteristic masses and/or micro calcifications. Mammography is believed to reduce mortality from breast malignant neoplasm. No other imaging technique has been shown to reduce risk, but breast self-exam (BSE) and physician examination are considered essential parts of regular breast care. In many countries routine mammography of older women is encouraged as a screening method to diagnose early breast cancer. The United States Preventive Services Task Force (US government-appointed expert panel from 1984-89) recommends screening mammography, with or without clinical breast examination, every 1–2 years for women aged 50 and older. Altogether clinical trials have found a relative reduction in breast cancer mortality of 20%, but the two highest-quality trials found no reduction in mortality. Like all x-rays, mammograms use doses of subatomic particles or electromagnetic waves to create images. The branch of medicine that specializes in imaging technologies then analyze the image for any abnormal findings. It is normal to use longer wavelength of a sinusoidal wave is the spatial period of the wave, X-rays (typically Mo-K) than those used for the use of electronic ionizing radiation to view objects such as skeleton. High frequency sound (about 20 kilohertz), ductography, positron emission mammography, photo elastic modulator and MRI are adjuncts to mammography. Mammography has a false-negative (missed cancer) rate of at least 10 percent. This is partly due to dense tissues obscuring the cancer and the fact that the appearance of cancer on mammograms has a large overlap with the appearance of normal tissues.
