Objective To establish the linear regression equation between body height and combined length of manubrium and mesosternum of sternum measured by CT volume rendering technique(CT-VRT) in southwest Han population. Methods One hundred and sixty subjects, including 80 males and 80 females were selected from southwest Han population for routine CT-VRT(reconstruction thickness 1 mm) examination. The lengths of both manubrium and mesosternum were recorded, and the combined length of manubrium and mesosternum was equal to the algebraic sum of them. The sex-specific linear regression equations between the combined length of manubrium and mesosternum and the real body height of each subject were deduced. Results The sex-specific simple linear regression equations between the combined length of manubrium and mesosternum(x3) and body height(y) were established(male :y=135.000+2.118 x3 and female: y=120.790+2.808 x3). Both equations showed statistical significance(P0.05)with a 100% predictive accuracy. Conclusion CT-VRT is an effective method for measurement of the index of sternum. The combined length of manubrium and mesosternum from CT-VRT can be used for body height estimation in southwest Han population.
