The crossover correction in dual photon absorptiometry with ¹⁵³Gd

Physics in Medicine & Biology, 1982
Considers one aspect of the methodology of dual photon absorptiometry which is specifically important when using 153Gd and which affects the absolute determination of bone mineral content. This is the contribution to the 44 keV energy window from the 100 keV energy caused by Compton events within the crystal and scatter within the patients.

Vertebral and Peripheral Bone Mineral Content by Photon Absorptiometry

Investigative Radiology, 1977
Dual photon absorptiometry with 153Gd was used to determine the bone mineral content of the lumbar spine of 46 subjects. The bone mineral content of the radius and ulna were measured on these same subjects using single photon absorptiometry. The bone mineral content at the peripheral sites was not a very accurate indicator of absolute bone mineral ...

Bone mineral analysis of the rat femur by direct photon absorptiometry

Calcified Tissue International, 1981
This report describes a method using direct photon absorptiometry (DPA) for determination in vivo of the bone mineral content to bone width ratio (BMC/W) in the rat femur. A significant correlation was noted between measurements by DPA and whole femur dry weight and ash weight.
