BONE DENSITY SCANS
Bone mineral density (BMD) assessment is one predictor of fracture risk and should be measured using dual energy x-ray absorptiometry (DXA) performed at two sites, preferably spine and hip
BMD results are reported as a T-score (number of standard deviations that BMD is above or below the mean of healthy young adults) or a Z-score (number of standard deviations that BMD is above or below the mean of normal controls matched for age).
The World Health Organization defines osteoporosis as a T-score ≤-2.5 and osteopenia as a T-score between -1 and -2.5.
BMD should be assessed in individuals with suspicion of osteoporosis to establish a baseline reading that can be used to inform future management. Indications for BMD assessment include:
Minimal trauma fracture
Women aged <65 years with risk factors for osteoporosis Women aged ≥65 years and men aged ≥75 years considering specific measures to prevent osteoporosis All users of glucocorticoids for >6 months
A DXA bone density scan is the gold standard method to determine if you have normal bone density, low bone density (osteopenia) or osteoporosis.
