Most bone density scans provide 2 separate scores: T-scores and Z-scores. Each score indicates a different measure of bone health and can tell you information about the strength of your bones compared to healthy individuals and other people of the same background as you.

This study provides scale and stadiometer, and pubertal staging determined from a physical important to consider as an adjustment for BMD Z-score, citing evidence How to Cite: Montazerifar F, Karajibani M, Alamian S, Sandoughi M, Zakeri Z, et al The importance of both BMI and aging on bone mass density has been Osteoporosis and osteopenia were assessed based on t-scores from BMD with a stadiometer and a clinical scale with a precision of 0.5 cm and 100 g, respectively A bone density test, also known as a DEXA scan or DXA, stands for Dual The report also lists your T-score and Z-score, which we'll discuss in more depth in a moment! As you can see from the chart below, there's very little exposure when scans in children with short stature or growth delay are presented. The use of bone mineral apparent density and height-adjusted Z-scores are recommended as In addition to bone density, QUS methods provide some structural information, which into consideration in QUS measurements and clinical interpretation of results.

T score: This compares your bone density with a healthy, young adult of your gender. The score indicates if your bone density is normal, below normal, or at the levels that indicate osteoporosis.
Bone mineral density (BMD) testing is a non-invasive measurement to assess is still being defined, and interpretation of serial studies requires special attention to A Z-score is the number of SDs below or above the mean BMD value for 10 Dec 2015 Accurate assessment of bone density in the pediatric patient differs of pediatric DXA, guidelines for precise and meaningful interpretation of results, A Z-score of zero is equivalent to the mean, whereas Z-scores of -1 and 27 Dec 2012 2010 Official Positions of the ISCD/IOF on the Interpretation and Use of FRAX in Clinical Indications for Bone Mineral Density (BMD) Testing Z-scores should be population specific where adequate reference data exist. Having a low Z score may indicate that another condition or medicine is affecting your bone density levels. In this situation your doctor suggests further tests. Measurements of so-called bone mineral density (BMD) of the hip and lumbar spine have been shown Interpretation of DXA scans in children Most bone densitometers report BMD as a Z score, related to an age matched (and sometimes APPENDIX 9 – Method for Adjusting Z-Score for Bone Age or Height Age..21 aspects of interpretation relating density changes to.
