2024年5月28日 · A DXA scan (bone density test) is a quick, painless way to check your bone health. It’s similar to a regular X-ray, but measures the strength and mineral content of your bones instead of just taking pictures of them.

A bone density test determines if you have osteoporosis — a disorder characterized by bones that are more fragile and more likely to break. The test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone.

2022年11月2日 · Also called a bone mineral density test (BMD), a dual-energy X-ray absorptiometry test (DEXA scan), or a peripheral screening test, a bone density scan checks the hips, spine, forearms, heel, or finger for signs of decreased bone mass.

2024年9月2日 · What Is a Bone Mineral Density Test? A bone mineral density test, sometimes just called a bone density test, detects whether you have osteoporosis, a word that comes from Greek...

2023年12月17日 · What Is a DEXA Scan? Testing your bone density – how strong your bones are – is the only way to know for sure if you have osteoporosis. This condition causes your bone tissue to break down faster...

2024年8月6日 · What is a DEXA scan? A DEXA scan is a high-precision type of X-ray that measures your bone mineral density and bone loss. If your bone density is lower than normal for your age, it indicates a...

2025年1月30日 · 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.

2022年8月10日 · Osteoporosis has been called a "silent" disease because the loss of bone progresses gradually without pain or symptoms until a fracture occurs. The best test to determine the state of your bones is called a DEXA scan, also known as a bone density test. What is a bone density test? Who should have a DEXA bone density test?

A bone density scan is a diagnostic radiology exam used to measure bone mineral content and mass. This is usually performed with an X-ray, called a DEXA scan, or with a computed tomography (CT) scan of the bones. Bone density scans can detect the depletion of bone calcium and protein, which increases your bone fracture risk.

2021年1月10日 · A central DEXA scan shows whether you have normal bone density, low bone density, or true osteoporosis. It can determine if your bone density is improving, staying the same, or getting worse. This helps your doctor decide if you …
