Differences in determining bone density scores have been found when comparing different bone
density machines. Reducing differences between machines will improve diagnostic agreement

between the Norland Excel, such as the one at Wildwood Clinic, and the GE Healthcare Lunar
Prodigy at the UW Osteoporosis Clinical Research Center.
