Gender determination by Morphometry measuring of the 12th thoracic vertebra three-dimensional reconstruction image / 中国法医学杂志

ABSTRACT

Objective This article aims to investigate the effect of gender determination for measuring the 12th Thoracic Vertebra by using computed tomography (CT) and explore the feasibility for the research of human skeleton measuring by CT technique in the ifeld of forensic anthropology.Methods After ascertaining 11 radial line indicators,we measured Multi-planner Reformation (MPR)image of the 12th Thoracic Vertebra. Four ratio indicators were calculated after eliminating measurement uncertainty of results. We inspected the effect of gender determination for measuring the 12th Thoracic Vertebra by using computed tomography (CT) on account of statistical measurement data.Results Gender determination of 12 indicators is remarkable after eliminating 3 unstable indicators. Sevene quations were established. The equation established by centrum indicators predicted sex up to 91.6% accuracy.Conclusion The morphometry indicators of 12th Thoracic Vertebra have gender difference. CT technology can accurately measure skeleton and is valuale for study of human skeleton measuring research in the ifeld of forensic anthropology.
