The validity of measuring bone density from roentgenograms by means of a bone density computing apparatus

Rat bone mineral content can be accurately determined from roentgenograms. Calcium changes of 4% or less are detectable. Bulk densities of dry bone, ash, and calcium of femur segments are highly related to in vivo x-ray densities ( r = .92) and can be predicted from roentgenograms using regression e...

Zusammenfassung:Rat bone mineral content can be accurately determined from roentgenograms. Calcium changes of 4% or less are detectable. Bulk densities of dry bone, ash, and calcium of femur segments are highly related to in vivo x-ray densities ( r = .92) and can be predicted from roentgenograms using regression equations.
