摘要

颅骨穹隆厚度(CVT)及其变化为了解个体的年龄和性别等生物属性提供了宝贵的信息。本文旨在评估 CVT 与年龄和性别的相关性,并使用计算机断层扫描(CT)图像建立一个回归模型,用于估计马来西亚亚成年人的年龄。共采集了 521 张 CT 图像(男性/女性:279/242;年龄范围:0-20 岁;马来人/中国人):年龄范围:0-20 岁;马来人/华人/印度人:马来/华人/印度人:221/145/155)。研究人员评估了 CVT 测量值与年龄和性别的相关性,包括额骨厚度 (FBT)、枕骨厚度 (OBT)、左顶骨厚度 (LPBT) 和右顶骨厚度 (RPBT),并制定了用于估计亚成年人年龄的回归公式。结果表明,CVT 测量值与年龄之间存在明显的相关性(p

Computed tomography study of cranial vault thickness in Malaysian subadult population.

Cranial vault thickness (CVT) and its variations provide valuable insights into an individual's biological attributes such as age and sex. This paper aimed to assess the correlations of CVT with age and sex and develop a regression model for age estimation in Malaysian subadults using computed tomography (CT) images. A total of 521 CT images (male/female: 279/242; age range: 0-20 years; Malay/Chinese/Indian: 221/145/155) were included in the study. Correlations of CVT measurements with age and sex, including frontal bone thickness (FBT), occipital bone thickness (OBT), left parietal bone thickness (LPBT), and right parietal bone thickness (RPBT) were assessed and regression formulae were developed for age estimation in subadults. A significant correlation between CVT measurements and age was demonstrated (p < 0.001). Age estimation was most accurate in the younger age group (< 2 years) at frontal and occipital, and accuracy decreases in the older age groups. Additionally, sexual dimorphism was evident in the frontal and parietal bone thickness within the age range of 3-6 years and 16-20 years, respectively. In conclusion, the findings suggested CVT measurements could be used to corroborate other age estimation methods for subadults.

期刊介绍: The International Journal of Legal Medicine aims to improve the scientific resources used in the elucidation of crime and related forensic applications at a high level of evidential proof. The journal offers review articles tracing development in specific areas, with up-to-date analysis; original articles discussing significant recent research results; case reports describing interesting and exceptional examples; population data; letters to the editors; and technical notes, which appear in a section originally created for rapid publication of data in the dynamic field of DNA analysis.
