| Research Abstract |
Bone mineral densities at trabecular bones of 18 vertebral bodies (from the first thoracic vertebra to the first sacral vertebra) were investigated using 1,031 CT data sets for the purpose of the contribution to the preventive medicine on the spinal disorders. The computerized scheme for the measurement of the vertebral body geometry was also designed and the correlation between the vertebral body geometry such as (1) width, (2) height, (3) depth, (4) cross-sectional area, and bone mineral density at the first lumbar vertebra was statistically analyzed using this scheme. The findings of this study suggested the new possibility of the loss of bone strength associated with the bone mineral density and the cross-sectional area.
