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. The bones that are most commonly tested are in the spine, hip and sometimes the forearm.

2022年11月2日 · A bone density test can help diagnose osteopenia and osteoporosis, which decrease bone density and strength, but does not show arthritis. It is a painless procedure that takes place at a hospital, medical clinic, or outpatient imaging center.

What Is a Bone Density Test? DXA is a non-invasive test to measure bone density. A bone density test is a measurement of how much mineral, such as calcium, you have in your bones. The most common and most versatile test is with dual-energy X-ray absorptiometry (DXA).

2020年6月23日 · Interpret Your Bone Density Scan Results. DEXA bone scan results scores are measured as T-scores, which is a comparison of a person’s bone density with that of a healthy 30-year-old adult. The lower bone density test results, the lower your total bone density, indicating osteopenia or osteoporosis. T-Score Bone Density Chart:

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.

2020年8月3日 · A bone density scan shows how much bone is in your hip, spine and forearm. It detects low bone density and osteoporosis. These conditions cause thinning and weakening of the bones, sometimes called “brittle bones.”

2024年9月2日 · A bone mineral density test examines segments of your bone through X-rays to detect osteoporosis. The test is quick and painless, and it gives you a snapshot of how strong...

2024年11月29日 · Bone density tests provide a precise measure of whether you have osteopenia or osteoporosis. Both sexes usually begin to lose bone thickness around age 50. However, women tend to lose bone more rapidly due to hormonal changes during menopause .

2025年3月10日 · A bone density test, or densitometry, is a scan that measures bone density. It is also called a dual energy x-ray absorptiometry (DXA) scan. The test uses x-rays to show if your bones have lost minerals, such as calcium.

2020年9月22日 · ANSWER: A bone density test uses a low dose of X-rays in a quick, noninvasive way to measure the amount of calcium and other minerals in a segment of bone, usually the hips and spine. By identifying decreases in bone mineral density, your health care provider can determine your risk of fractures, and diagnose and monitor osteoporosis progression.
