WebbThe DEXA Scan is a quick and painless, whole body scan that uses medical grade technology to provide measurements of Body Fat, Muscle Mass, and Bone Health. A DEXA Scan (Dual-Energy X-ray Absorptiometry), uses two … WebbA dual-energy x-ray absorptiometry scan (DEXA), or bone density scan, is a special type of x-ray that measures bone mineral density (BMD). It provides information about bone strength or fragility and the risk of fractures or broken bones. A higher density generally indicates a lower risk of fracture.
WebbRadiation in Healthcare Radiation in Healthcare: Bone Density (DEXA Scan) DEXA (dual x-ray absorptiometry) scans measure bone density (thickness and strength of bones) by passing a high and low energy x-ray beam (a form of ionizing radiation) through the body, usually in the hip and the spine. WebbAs the X-ray enters your body, it passes through your skin, muscles, and organs, as this type of soft tissue cannot absorb the energy of the X-ray. This appears dark on the film as it is now exposed. However, bone absorbs X-ray energy and does not expose the film. This area appears light or white on the film. This is how an X-ray image is created!
Webb1 apr. 2008 · The results of a DEXA equipment survey based on an in-house developed QA protocol are presented. Measurements show that the total effective dose to the patient from a spine and dual femur DEXA examination on the latest generation DEXA systems is comparable with a few μSv at most.
