摘要：

A longer dual-energy X-ray absorptiometry (DXA) femur scan field might be useful for the detection of atypical, subtrochanteric femur fractures (ASFF). Thirty adult subjects underwent triplicate measures of femoral neck (FN) and total hip (TH) bone mineral density (BMD) by DXA using a conventional (i.e., short) and a longer femur scan field. Differences in measured BMD between the 2 scan field lengths were small and less than the precision error inherent in DXA testing. A longer proximal femur scan field does not substantially alter BMD measurements made at the FN and TH and may be useful for the detection of ASFF in clinical practice.
