DEAR DR. ROACH: The results for my last bone density test show not only a T-score but also a Z-score. For my spine (L1 through L4), the T-score is -3.4, while the Z-score is -1.4. Can you please explain the difference between the two measurements? I realiz...
Bone density or bone mineral density is the amount of bone mineral in the bone tissue. Bone density measurements are used in clinical medicine as an indicator of osteoporosis, a disease that makes your bones weak, and increases the risk of fractures. It can also indicate your response to trea...
The results of a bone mineral density (BMD) test are typically expressed in terms of T-scores and Z-scores. A T-score compares a person's BMD to that of a healthy young adult of the same gender. A score of -1.0 or above is considered normal, while a score between -1.0 and -2.5 ...
DXA scan, a bone imaging test to assess your risk for osteoporosis and fractures. The test determines your bone mineral density (BMD), which is compared to two norms: a T-score (that of a young, healthy adult) and a Z-score (adults of your same age, sex, race, height, and weight...
(DEXA or DXA) can assess your bone density. It provides measurements called T-scores that may indicate osteopenia or osteoporosis. The scores also help determine your vulnerability to to bone fractures. A T-score ranging from -1 to -2.5 indicates osteopenia. A score below -2.5 is classified ...
Osteoporosis is a bone condition that’s primarily caused by bone loss. This bone disease most often affects women because the estrogen changes that occur during menopause sharply decrease bone density. This drop in bone density affects strength and bala
' The answer is yes! Although a female body has approximately one tenth of the amount of testosterone as that of a man, it still plays a role in their development. Testosterone helps ensure that a woman's muscle and bone mass are stabilized, ensuring that they have a less likely chance ...
What Is Osteopenia? Osteopenia is loss of bone density. If you have low bone density, your bones lack enough minerals, which makes them weak. Osteopenia can eventually become osteoporosis. About 40 million people in the U.S. have osteopenia. Your bones are usually at their densest when you...
The bone mineral density is measured by T- score which is relative to normal age, young, matched control (25 year old women) and Z-score which is relative to similar aged patients. How is osteoporosis measured? It is measured by DEXA scan at the hip through the T –score. DEXA scan ...
Known as the 'gold standard' due to its reliability and applicability, dual-energy X-ray absorptiometry (DEXA) is an X-ray machine designed to measure bone density that doubles up as a neat little body fat percentage scanner. You’ll find them at pop up clinics, but again they’re pretty...
