Bone Density Test, Osteoporosis Screening & T-score Interpretation

Abnormal Bone Density Scan:

When bones are somewhat thin, the condition is called osteopenia. When bones become very thin, the condition is called osteoporosis. Bone density tests provide a precise measure of whether you have osteopenia or osteoporosis. A bone density scan uses low dose X-rays to see how dense (or strong) your bones are. Bone scans are used primarily to detect the spread of metastatic cancer.Because cancer cells multiply rapidly, they will appear as a hot spot on abone scan.

Since estrogen keeps bones strong, can getting your estrogen levels checked help? Rarely, perimenopausal women with heavy periods might need hormone checks. It’s also helpful to stay informed about new studies and possible new treatments. If you’re such a good point interested in talking with other people who have osteoporosis, the NOF has support groups around the country. Your doctor may advise you to start weight-bearing exercises, balance exercises, strengthening exercises, or a weight loss program.

Rarely, some people with osteopenia may experience bone pain or weakness. The condition is usually detected when a person has a BMD screening. Doctors use Z-scores to diagnose osteoporosis in children, teenagers, premenopausal females, and younger males. A score of -2.5 or less suggests that a person may have secondary osteoporosis, which does not result from aging. T-scores reflect how bone density compares with that of a typical, young, healthy person, whereas Z-scores use the bone density of those with similar characteristics for comparison.

During a bone density scan, a type of X-ray called dual energy X-ray absorptiometry is passed through your body. Bone density scans are often used to diagnose or assess your risk of osteoporosis, a health condition that weakens bones and makes them more likely to break. A bone density scan (DXA) scan can be used to check your bone mass. It checks the thickness of your bones to see if you have a higher risk of a bone fracture. DEXA gives healthcare providers a ‘baseline measurement.’ That means they can compare the current test results to future results to determine whether bone density decreases over time. The BHOF notes that Z-scores can be misleading because older adults commonly have low bone density.

Your bone density is low, and your bones are at higher risk of fracture. Your T-score is worked out by comparing your bone density with the bone density of an average healthy adult of your gender. Your T-score is the number of units that your bone density is above or below the average. If your bone density is low, you have a higher risk of a bone fracture.

While a bone scan is sensitive to bone abnormalities, it is less helpful in determining the cause of the abnormality, according to MayoClinic.com 1. A bone scan is a nuclear imaging test physicians use to look for areas of increased or decreased bone metabolism. Physicians often use this study in conjunction with other tests to diagnose bone infections, cancer or other degenerative bone diseases.

During the examination, you are moved through a ring-shaped CT scanner while lying down. An X-ray source in the CT scanner rotates around the try what he says part of your body that is being scanned. Depending on how much of the body is scanned, the procedure takes about 5 to 30 minutes in total.

They can also recommend diet and lifestyle changes that may help to lower your risk of a fracture. Osteoporosis results when you to lose bone faster than your body can create see new bone tissue. The Z-score is the difference between your bone mineral density and the average bone mineral density for healthy people of your age, ethnicity, and sex.

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). This is used to diagnose osteoporosis BEFORE you break a bone, help to estimate your chances of breaking a bone in the future, and monitor the effectiveness of osteoporosis treatments. This is a very simple test that only takes a few minutes to do.

Up until about age 30, a healthy person builds more bone than he or she loses. But after age 35, bones begin to break down faster than they build up. Even in a healthy person, bone density decreases throughout life, by less than 1 percent per year. A doctor can measure a person’s bone density with a DEXA scan.

The U.S. Preventive Services Task Force recommends that women over age 65 have a bone mineral density test. The Task Force also recommends this screening for women of any age who have factors, identified by a health care provider who uses a formal risk-assessment tool, that raise their chance of osteoporosis. Screening for osteoporosis is recommended for all women over age 65.
