Bone Densitometry (QCT)

Bone Densitometry is a non-invasive procedure in which your bone mineral density (BMD) is measured and compared against that of a normal population of people who are the same age, weight, sex, and ethnic background. We use a very low energy X-ray beam from a CT scanner to produce an image of the lumbar spine or hip. Your doctor uses the information gathered from this study to assess your bone condition, risk of fracture, and to assist in deciding whether treatment is necessary. Quantitative Computerized Tomography (QCT) bone densitometry is the most precise method of assessing bone health and risk of osteoporosis. QCT provides a measurement that is within 0.7%—1.1% of your true bone mass, which is much more precise than the more commonly used “DEXA” exam. If you are already undergoing treatment or therapy for osteoporosis or osteopenia (low bone density), we recommend periodic follow-up studies to assess changes in bone density. This study takes about 15 minutes.
