Comparison of CT scanning with photon absorptiometric measurement of bone mineral content in the appendicular skeleton.
Traditional methods of bone mineral analysis were compared to a new technique using computerized tomography (or CT scanning). The correlation between the CT values for long bones in the dog and actual calcium content was 0.9942. The correlation between two photon absorptiometric techniques and CT values were also 0.9981 and 0.9962. The precision of repeated scans was +/-2%. It is suggested that the CT scanner will allow bone mineral analysis to be performed with accuracy and precision.
