Cross-Calibration of GE Healthcare Lunar Prodigy and iDXA Dual-Energy X-Ray Densitometers for Bone Mineral Measurements

Figure 1

Linear correlations and 95% confidence intervals between bone mineral density (BMD) values measured by the GE Healthcare Lunar Prodigy and iDXA. (a) Femoral neck, (b) total hip, (c) lumbar spine (L2–L4), and (d) total body of the study subjects. Linear correlation () of BMD values between DXA devices was high at spine and at hip, whereas the association was slightly lower at total body BMD.
