Annually, approximately 9 million osteoporotic fractures are diagnosed worldwide.
As osteoporosis is a condition classified as a public health issue—often asymptomatic and, to
some extent, neglected—early diagnosis of reduced bone mineral density remains a significant
challenge. In this study, the Pearson correlation coefficient was employed to compare the
results of radiographic bone densitometry (RBD) using a densitometric reference based on
a penetrometer manufactured from aluminum alloy 6063 ABNT and a mobile application
specifically developed to perform RBD measurements, with results obtained through dualenergy
X-ray absorptiometry (DXA). The analysis was conducted on dry bones (ultradistal
portions of radii and femoral necks) from healthy dogs. The results for the ultradistal portion of
the radius obtained via the mobile application demonstrated good correlation with DXA (R=0.7),
while the femoral neck showed very good correlation (R=0.8). It was concluded that the mobile
application analyzed in this study may, in the near future, become an important tool for the
effective assessment of bone mineral density.
