摘要
活体年龄推断是法医学研究的重要任务之一,尤其是在青少年及成人早期。基于左手X线片、口腔曲面断层片及锁骨胸骨端CT检查已是广泛应用的成熟手段。然而,X射线技术对人体辐射较大,在非诊疗目的下的影像辐射不符合当今主流的医学伦理。MRI为无辐射的断层影像,是目前活体年龄推断的研究和发展方向之一。本文通过总结MRI在既往年龄推断研究中的常用指标及分析方法,以期了解其发展动态,为后期相关研究提供思路。
One of the major tasks in the forensic field is age estimation in living individuals,especially in adolescents and young adults.The X-ray examination of left hand,panoramic radiograph and CT scan of the sternal end of clavicles are mature means that are widely used.However,the X-ray technique has great radiation on the human body,and imaging radiation for non-diagnosis and treatment purposes does not conform to the current mainstream medical ethics.MRI is nonradioactive tomographic imaging and is one of the research and development directions in forensic age estimation in living individuals now.This paper summarizes the common indicators and analysis methods of MRI in previous research of age estimation,in order to get better understanding of its trends and provide a clue for future relevant studies.
