摘要： 目的 建立基于成人耻骨MSCT三维重组推断活体年龄的方法，并验证其准确性与可靠性。 方法 收集300名年龄大于17岁的志愿受试者的耻骨联合面容积再现（volume rendering，VR）图像，对不同年龄段人群运用耻骨联合面推断年龄的方法和公式，对受试者的年龄进行推断。 结果 300名受试者中，生物学年龄与实际年龄相差１岁以内的117例，相差>１~2岁的178例，相差大于2岁的5例。 结论 MSCT三维重组技术可以用于成人活体年龄的推断，推断结果准确性与可靠性较高。

Abstract: Objective To establish a method for the age estimation of adult living donor based on pubic MSCT three-dimensional reconstruction and verify its accuracy and reliability. Methods The volume rendering （VR） image data of pubic symphysis surface were collected from 300 volunteers aged over 17 years old. According to different age groups, the age estimation of these volunteers was performed by the method and formula of pubic symphysis surface. Results In the 300 volunteers, the difference between biological age and actual age was <1 year in 117 cases, >1-2 years in 178 cases, >2 years in 5 cases. Conclusion MSCT three-dimensional reconstruction technology of pubic symphysis surface can be used to estimate the age of adult living donor, which can provide a high accurate and reliable result.
