Skeletal Anatomy in Densitometry,ssage of photon energy from the posterior to anterior direction. They are properly characterized as posteroanterior (PA) spine studies. Nevertheless, these studies are often called anterior-posterior (AP) spine studies, probably because plain films of the lumbar spine are acquired in the AP projecticurriculum 发表于 2025-3-29 11:23:36

Computer Basics, of densitometry today. Appendix XI is a glossary of computer terms that should be part of the vocabulary of the densitometry technologist. In the 21st century, dual X-ray absorptiometry (DXA), single X-ray absorptiometry (SXA), and ultrasound devices are computer-driven. Even techniques such as som无脊椎 发表于 2025-3-29 23:31:35
The Importance of Precision,l result in the setting of no real biologic change when the test is repeatedly performed in an identical fashion. Like all quantitative tests in clinical medicine, no bone densitometry technique is perfectly reproducible. This is true even when the bone density test is performed in exact accordance蘑菇 发表于 2025-3-30 01:56:43
Radiation Safety in X-Ray Densitometry,that they are biologically insignificant. Similarly, the technologist operating an X-ray densitometer on a regular basis is extremely unlikely to be exposed to a significant amount of radiation. Nevertheless, no amount of radiation should be considered inconsequential. The principle of “as low as re发生 发表于 2025-3-30 05:10:24
Quality Control,inical research rather than patient data collected as part of medical care. Quality control, although absolutely necessary in clinical research, is no less necessary in clinical practice.
