Accuracy and precision of computer-assisted analysis of bone density via conventional and digital radiography in relation to dual-energy x-ray absorptiometry.
Abstract: To evaluate the precision and accuracy of assessing bone mineral density (BMD) by use of mean gray value (MGV) on digitalized and digital images of conventional and digital radiographs, respectively, of ex vivo bovine and equine bone specimens in relation to the gold-standard technique of dual-energy x-ray absorptiometry (DEXA). Methods: Left and right metatarsal bones from 11 beef cattle and right femurs from 2 horses. Methods: Bovine specimens were imaged by use of conventional radiography, whereas equine specimens were imaged by use of computed radiography (digital radiography). Each specimen was subsequently scanned by use of the same DEXA equipment. The BMD values resulting from each DEXA scan were paired with the MGVs obtained by use of software on the corresponding digitalized or digital radiographic image. Results: The MGV analysis of digitalized and digital x-ray images was a precise (coefficient of variation, 0.1 and 0.09, respectively) and highly accurate method for assessing BMD, compared with DEXA (correlation coefficient, 0.910 and 0.937 for conventional and digital radiography, respectively). Conclusions: The high correlation between MGV and BMD indicated that MGV analysis may be a reliable alternative to DEXA in assessing radiographic bone density. This may provide a new, inexpensive, and readily available estimate of BMD.

The research article evaluates how accurately and precisely bone mineral density (BMD) can be assessed using digital and conventional radiography methods, compared to the widely used technique of Dual-energy X-ray Absorptiometry (DEXA).
Methodology
- The study involved the use of left and right metatarsal bones from 11 beef cattle and right femurs from 2 horses.
- The bovine specimens were imaged using conventional radiography, while equine specimens were imaged using computed radiography.
- Each specimen was then scanned using the same DEXA equipment.
- The resulting BMD values from each DEXA scan were paired with the Mean Gray Value (MGV) obtained through software from the corresponding digital or digitalized radiographic image.
Results
- The Mean Gray Value (MGV) analysis of digital and digitalized radiographic images proved to be precise and highly accurate in assessing BMD, as compared with the DEXA technique. This was shown by the low coefficient of variation (0.1 and 0.09 for digitalized and digital radiography, respectively).
- A high correlation was observed between the MGV and BMD measurements (correlation coefficient of 0.910 and 0.937 for conventional and digital radiography, respectively).
Conclusions
- The high correlation between MGV and BMD suggests that MGV analysis could be a reliable alternative to DEXA when measuring radiographic bone density.
- This could potentially provide a more affordable and readily available estimate of bone mineral density.
