Age estimation by quantitative features of pubic symphysis using multidetector computed tomography.

Area of Science:

• Forensic Anthropology
• Radiology
• Osteology

Background:

• Macroscopic pubic symphysis assessment is a standard method for age estimation.
• Postmortem computed tomography (PMCT) offers a non-invasive approach to examine pelvic bones.
• Previous 3D imaging studies show variability due to software differences.

Purpose of the Study:

• To evaluate the feasibility of age estimation using planar PMCT images of the pubic bones.
• To assess the correlation between pubic bone morphology and age in a diverse dataset.
• To investigate the utility of soft tissue measurements in conjunction with skeletal analysis.

Main Methods:

• Retrospective review of PMCT scans from 199 individuals with known age and sex.
• Analysis of coronal and axial sectional images at the pubic symphysis center.
• Measurement of pubic bone length and connective tissue thickness.

Main Results:

• A significant positive correlation was found between coronal pubic bone length and age.
• Pubic bone length may serve as a feasible cutoff value for age estimation.
• Connective tissue thickness showed a trend of decreasing with age.

Conclusions:

• Planar PMCT images show potential for forensic age estimation, particularly pubic bone length.
• While current prediction intervals are broad, PMCT can complement other forensic findings.
• Further refinement of PMCT analysis may enhance its practical application in age determination.
