Bone Density

The National Osteoporosis Foundation estimates 55% of people age 50 and older in the United States have osteoporosis or low bone mass. Of these, more than 14 million men and 30 million women are affected by this condition. Osteoporosis is treatable and preventable. Early diagnosis, therapeutic intervention and the use of bone density testing to diagnose and monitor response to therapy have greatly improved the prognosis for patients.

DEXA (Dual Energy X-ray Absorptiometry) is the type of test utilized by our centers for measuring bone mineral density. The scan is a reliable test to determine early stages of bone loss associated with osteoporosis, a disease in which bone density decreases, making bones brittle and prone to fractures. For the exam, you will be asked to lie on the exam table as the DEXA scanner passes over your hip area. This is the most accurate position to determine bone density. The exam is painless and noninvasive and generally takes approximately 20 minutes to complete.

The DEXA scan results are reproducible, allowing measurements to be taken over time showing progression of disease or improvement in bone density due to treatment.

After your exam, the results will be reviewed by our Radiologist and a report will be sent to your doctor.
