Dexa Scan

Assessing Bone Density and Health

Dexa Scan, or Dual-Energy X-ray Absorptiometry, is a state-of-the-art imaging technique used primarily to measure bone mineral density. It's an essential tool in the diagnosis of osteoporosis and assessment of fracture risk.

The Dexa Scan is a quick and painless procedure that utilizes low-dose ionizing radiation to produce images of the inside of the body, mainly the lower spine and hips, to measure bone loss. It's highly accurate in tracking changes in bone density over time.

  • Applications: Besides osteoporosis, Dexa Scan is used to determine an individual's risk for developing fractures and to assess an individual's response to osteoporosis treatment.
  • Body Composition: Dexa Scan can also measure body composition, including body fat percentage and lean muscle mass.
  • Safety: While the scan involves radiation, the dose is very low, making it a safe procedure for most individuals.

The results from a Dexa Scan, often termed as T-scores and Z-scores, help healthcare providers understand bone health, the risk of fractures, and whether any treatment is necessary.

Understanding the Results

The T-score compares your bone density with what is normally expected in a healthy young adult of your sex. Z-score compares your bone density to what is normally expected for someone of your age, gender, weight, and ethnic or racial origin.
