Kusama, M. Kai, E. Yabuuchi, Y. Bessho] The patient dose from in vivo measurement of bone mass and density was estimated by a phantom method. The measurement methods studied were microdensitometry (MD method), single photon absorptiometry (SPA), dual energy X ray absorptiometry (DEXA), quantitative computed tomography (QCT) and conventional X ray photography (X-P) for vertebrae, all of which have been used for mass screening or clinical examination of osteporosis. The organ absorbed doses from the QCT and X ray photography were several mSv and these values were one to two orders of magnitude higher than those from the DEXA method. The effective dose and entrance skin dose from the QCT and X ray photography were one to two orders of magnitude higher than the DEXA, which were µSv and some ten µSv, respectively. The application of X-P and QCT for a young population should be carefully judged.
