Question: Does femoral bone mineral density reflect histologically determined cortical bone volume in hemodialysis patients?
Answer: The usefulness of l-BMD for predicting bone volume is limited most probably because of interference by soft tissue calcifications. In contrast, f-BMD shows significant association with cortical porosity.
yes
