D. Felsenberg et al., RECENT DEVELOPMENTS IN DXA - QUALITY OF NEW DXA MXA-DEVICES FOR DENSITOMETRY AND MORPHOMETRY/, European journal of radiology, 20(3), 1995, pp. 179-184
The introduction of new devices demands the assessment of their capabi
lities in established terms. The accuracy, reproducibility and spatial
resolution of in vitro (phantom) osteodensitometric and morphometric
measurements of QDR 2000 Plus and EXPERT are presented. Design details
of these DXA/MXA-devices are listed and discussed in combination with
the data acquired in the test measurements and calculations. The imag
e quality will improve with further software developments. The long-te
rm reproducibility and in vivo reliability remains to be evaluated.
