The precision of BMD (%CV) was less than 1%, but EXPERT was relatively less efficient than DPX-L. The BMDs determined by three sets of EXPERT (A, B and C) closely correlated in each other (r=0.99999 in EXPERT A vs. B, r=0.99977 in EXPERT A vs. C and r=0.99966 in EXPERT B vs. C), and good correlation was observed between the value determined each of three sets of EXPERT (A, B and C) and the value determined by DPX-L (r=0.99983, 0.99990 and 0.99921 in DPX-L vs. EXPERT A, B and C, respectively). The BMD values ranged within 3% when the phantom was shifted from the center (±3cm), and ranged within 4% when MIX-DP was added to a phantom. The results indicate that fan-beam type DXA system can measure BMD with high precision, although the BMD values measured by EXPERT were affected slightly by positioning or physical constitution of patient. It is also possible that the values measured by fan-beam type DXA system are availablefor comparison in each other or comparison with the value measured by pencil-beam type DXA system.
