APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -A DEXA scan is a type of medical imaging test. It uses very low levels of x-rays to measure how dense your bones are. DEXA stands for “dual-energy X-ray absorptiometry.” Medical experts consider DEXA scans to be the most useful, easy, and inexpensive test for helping to diagnose osteoporosis.

Detailed explanation-2: -The most commonly used BMD test is called a central dual-energy x-ray absorptiometry, or central DXA test. It is painless – a bit like having an x-ray. The test can measure bone density at your hip and lumbar spine.

Detailed explanation-3: -Dual-energy X-ray absorptiometry (DXA or DEXA) is a scan that is used to determine the density of bone to assess its strength. It is a standard method for diagnosing osteoporosis; used in combination with risk factors (the so-called “FRAX” method), it is also considered an accurate way to estimate fracture risk.

Detailed explanation-4: -A procedure that measures the amount of calcium and other minerals in a bone by passing x-rays with two different energy levels through the bone. A dual energy x-ray absorptiometry shows the strength and thickness of a bone and is usually done in the lower spine, hip, lower arm, wrist, fingers, and heel.

Detailed explanation-5: -Unlike ordinary X-rays, DEXA scans can measure tiny reductions in bone density. This makes it possible to diagnose osteoporosis in its early stages, before you break a bone. A DEXA scan also uses a low dose of radiation, which means the risks to health are much lower than with standard X-rays.
