Bone density scanners are a valuable tool for diagnosing and monitoring bone health, particularly in patients who are at risk for or already have osteoporosis. A bone density scanner, also known as a dual-energy X-ray absorptiometry (DXA) scan machine, is a specialized type of X-ray machine...
Experience the excellence of the Horizon DXA System from Hologic at DXAPerformance.com. Our cutting-edge bone density scans offer unparalleled precision for better health outcomes.
Low or very low Z-scores should trigger additional evaluations. Interpretation of DXA scan results should be done within the context of other relevant clinical information. Even children without low Z-scores may be not be achieving their genetic potential for bone mass....
Many bone densitometry practices re-enter patient and DXA scan data when creating reports. Accuracy is critical because interpretation is based on this data. Key patient information includes gender, date of birth, and ethnicity. Important bone mineral density data includes BMD, T-Scores, and Z-Sco...

None of the children had BMI z-scores below minus 2. Limitations of the BIA method is especially the responsiveness to variations in the hydration state seen with age, size, ethnicity, temperature, clinical conditions, fasting state, bladder voiding and exercise8,10 but also positioning of the ...
(P=0.007). As expected, the ED group had significantly lower weight and BMI s.d. scores (P<0.001) than the controls. The controls were 2.9 cm taller, equivalent to 0.4 s.d. scores, but not significantly so (P=0.2). The mean BMI s.d. scores of 0.34 (s.d. 1.19) in the ...
A retrospective chart review study of these adults seen at an urban academic rehabilitation clinic and who underwent DXA scan(s). BMD and Z-scores for the lumbar spine, hips, and femoral (neck and total) were recorded. The change in BMD and Z-scores from baseline to follow-up DEXA, Gros...
