  • history began more than 100 years ago. In the field of dentistry, crude devices by today' s standards were developed in the late 19th century to evaluate the density of the bone in the mandible. The advances in technology continued, albeit slowly, for the first half of the 20th century, gaining some speed in the 1960s and 1970s. The introduction of dual-energy X-ray absorptiometry in the late 1980s truly opened the door to clinicians' offices for bone densitometry.

  • Harrison's Internal Medicine Chapter 4. Screening and Prevention of Disease Screening and Prevention of Disease: Introduction A primary goal of health care is to prevent disease or to detect it early enough that intervention will be more effective. Strategies for disease screening and prevention are driven by evidence that testing and intervention are practical and effective. Currently most screening tests are readily available and inexpensive. Examples include tests that are biochemical (e.g., cholesterol, glucose), physiologic (e.g., blood pressure, growth curves), radiologic (e.g.

  • Chapter 004. Screening and Prevention of Disease Examples include tests that are biochemical (e.g., cholesterol, glucose), physiologic (e.g., blood pressure, growth curves), radiologic (e.g., mammogram, bone densitometry), or tissue specimens (e.g., Pap smear, fine-needle aspirations). In the future, it is anticipated that genetic testing will play an increasingly important role for predicting disease risk (Chap. 64). However, such tests are not widely used except for individuals at risk for high-penetrance genes based on family or ethnic history (e.g., BRCA1, BRCA2).

  • Bone densitometry (BD) is an extraordinary clinical tool. It provides a safe, non-invasive window to the skeleton. Through that window, a physician can obtain vital clinical information that enhances diagnosis and improves patient management. Further, much has changed in the last decade to make bone densitometry the especially fascinating field of medicine it is today, incorporating imaging, physics
