[Investigations of the mineral topography in human vertebral bodies. A comparison of results derived from bone-ashing, photodensitometry and attenuation coefficients by CT (author's transl)].

A method for the in vivo investigation of the mineral distribution in human vertebral bodies by the aid of computed tomography is presented. The attenuation coefficients resulting from transversal tomograms of vertebral spongiosa are compared with the results of bone ashing from in vitro investigations. Computed tomography values, ash weights and photodensitometric values show a high degree of correlation.
