Quantitative Computerized Tomography (BRSMQCT)
Principal Investigator
Research Area:
Skeletal physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Hip and spine morphology data was collected by quantitative computed tomography (QCT) technology in bed rest subjects. The QCT scan was used to measure true bone density volume, not just bone mineral density (BMD) per unit area. The QCT measured both cortical and trabecular bone. A more sensitive QCT technique was used to obtain these measurements which revealed how bone mass is geometrically distributed over a 3-dimensional space.
