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.
将传统的骨矿物质分析方法与一种使用计算机断层扫描(或CT扫描)的新技术进行了比较。犬类长骨的CT值与实际钙含量之间的相关性为0.9942。两种光子吸收测定技术与CT值之间的相关性也分别为0.9981和0.9962。重复扫描的精度为±2%。有人认为,CT扫描仪将能够准确、精确地进行骨矿物质分析。
