چکیده انگلیسی
In this study, we evaluate the ability of digitized digital X-ray radiogrammetry (DXR) bone mineral density (BMD) to identify women with reduced BMD at femoral neck, assessed by dual-energy X-ray absorptiometry (DXA). The study population contained women with recent low-energy distal radius fracture and women recruited from the general population, all aged 50 yr or older. The correlation between hand BMD and femoral neck BMD was r = 0.65 (p < 0.001). We used a triage approach where 2 cutoffs for DXR T-score were defined at which patients with 90% sensitivity and 90% specificity could be identified to have or not have reduced BMD at femoral neck, defined as T-score â¤Â â2.5 standard deviation (SD). The upper and lower DXR T-score cutoffs were â1.2 and â2.7, respectively. Applying the triage approach in the whole cohort, 32% would require a central DXA assessment to determine the presence or absence of femoral neck T-score â¤Â â2.5 SD. Our data suggest that DXR can be used to reduce the numbers of patients in need of DXA femoral neck and may, thus, be of clinical value where access to DXA is limited.
