Quantitative computed tomographic evaluation of femoral bone mineral content in renal osteodystrophy compared with radial photon absorptiometry.

摘要: The computed tomography (CT) numbers of cortical bone at the level 20 cm (CT20) and spongiosa in lateral condyle 2 (CT02) from distal end femur were obtained by a quantitative CT method compared with mineral density mostly within radius (BMD) photon absorptiometry. study included 47 patients chronic renal failure not dialyzed or induced to regular hemodialysis 4 weeks (group 1), 28 on for more than one month 2), ten healthy volunteers 3). measures content (BMC), namely CT20, CT02, BMD, terms their abilities distinguish members various groups. For group 1 3, greatest variation BMC was difference which primarily measurement spongiosa. groups 2, cortex. reproducibility CT02 estimated as almost equal values intervals 10 months'more » duration hemodialysis. results indicated that useful evaluating progress early stage osteodystrophy, it is recommended this QCT should be performed once twice year.« less
