Virtual computed tomography morphometry of the patella for estimation of sex using postmortem Japanese adult data in forensic identification

Description
Summary:•CT morphometry of the patella, especially with 3-D bone volumetry, was examined to estimate sex.•Sex-related differences were the most evident for bone mass volume.•The mean CT value showed an age-dependent decrease and was particularly low in females.•Virtual CT morphometry of the patella using an automated analyzer may be useful for sex estimation. In forensic anthropological identification of human remains and single bones, computed tomography (CT) data analysis facilitates volumetric and radiographic density analyses, and a recently developed automated analysis system markedly improved the performance, accuracy, and reproducibility of three-dimensional (3-D) reconstruction. The present study aimed to investigate virtual CT morphometry of the patella for the estimation of sex using postmortem CT data of forensic autopsy cases of Japanese individuals aged ≥18 years (total n=220; 110 males and 110 females; estimated postmortem interval females; p60years. These findings indicate the efficacy of virtual CT morphometry of the patella using an automated analyzer for sex estimation.
