Age Estimation through Hounsfield Unit Analysis of Pelvic Bone in the Romanian Population

<b>Background</b>: Bone density is affected by age- and sex-related changes in the os coxae, often known as the pelvic bone. Recent developments in computed tomography (CT) imaging have created new opportunities for quantitative analysis, notably regarding Hounsfield Units (HU). <b>Objectives</b>: The study aims to investigate the possibility of using HU obtained from os coxae CT scans to estimate age in the Romanian population. <b>Methods</b>: A statistical analysis was conducted on a sample of 80 pelvic CT scans in order to find any significant correlation between age, sex, and variation in density among the different pelvic bone locations of interest. According to the research, pelvic radiodensity measurements varied significantly between male and female participants, with men having greater levels. This technique may be valuable for determining an individual's sex precisely, as evidenced by the substantial association found between HU levels and changes in bone density associated with sex. <b>Results</b>: The analysis of variance underscores that HU values exhibit a significant negative relationship with radiodensity, with a general trend of decreasing HU with increasing age. The equation derived from the ordinary least squares OLS regression analysis can be used to estimate the age of individuals in the Romanian population based on their HU values at specific pelvic sites. <b>Conclusions</b>: In conclusion, the application of HU analysis in CT imaging of the coxae represents a non-invasive and potentially reliable method for age and sex estimation, and a promising avenue in the field of human identification.
