Introduction
The bone density report primarily assesses the mineral density of the bones, usually evaluated based on T-scores and Z-scores. The T-score is the most significant indicator for diagnosing osteoporosis. A T-score greater than -1 indicates normal bone density; a T-score between -2.5 and -1 suggests mild reduction in bone mass; and a T-score less than -2.5 indicates severe osteoporosis.
A bone density report primarily evaluates the mineral density of the skeleton, typically assessed using T-scores and Z-scores. The specific analysis is as follows:
The T-score is the most significant indicator for diagnosing osteoporosis. A T-score greater than -1 indicates normal bone density; a T-score between -2.5 and -1 suggests mild reduction in bone mass; and a T-score below -2.5 indicates severe osteoporosis. The Z-score reflects the severity of osteoporosis. Generally, a Z-score above -2.0 is considered normal, while a Z-score ≤ -2.0 means bone density is lower than that of healthy individuals of the same age—the lower the value, the more severe the osteoporosis.
Clinically, it is recommended that patients return to an orthopedic specialist after receiving their bone density report. Regardless of the results, a comprehensive evaluation by a physician is essential.
