A method is given for simultaneous in vivo measurement of mineral and collagen metabolism of the bone. Accretion rates of 47-calcium as a chlorid into the bone are representative for bone mineralisation and of 99m-technetium labelled pyrophosphate for collagen metabolism. Compartmental models used for analysis are presented. Bone accretion rates are given in mg, or mMol respectively per unit time for the skeleton, by computation of the specific activity of 47-calcium and 99m-Technetium pyrophosphate and rational bone accretion as registered by total body profile scanning technique. The results obtained in five normal volunteers are presented.
