“…Several methods were used to validate the reliability; first, MRI was chosen as the measuring method, with measurements obtained through MRI images, which guarantee high reliability and low subjectivity of the measurements taken, as opposed to direct measurement from bones, which has a high risk of subjectivity (Yasar Teke et al, 2018). Second, two researchers obtained measurements of the tested dimensions at different times and in different situations.…”

Introduction: Personal identification relies on sex identification. Anthropometric measurements are known to be reliable for sex identification in forensic cases. MRI has recently emerged as the preferred method for determining anthropometric measurements. The proximal ends and shafts of the radius and ulna are both sexually dimorphic. However, research on the utility of their distal ends for sex determination is limited. Aim: To assess the reliability and validity of some anthropometric dimensions at the distal epiphyseal ends of radius and ulna for sex identification using Magnetic Resonance Imaging among a sample of the Egyptian population to adopt this method for sex identification in forensic practices. Methodology: This cross-sectional retrospective study was conducted on 200 subjects (100 males and 100 females) using archived MRI films. Four dimensions were measured: the radial distal end width, radial height, ulnar distal end width, and ulnar styloid process length. The data was statistically analysed. Results: The tested dimensions were found to be reliable and valid in sex discrimination with accuracy up to 87.5% for radial dimensions and up to 83.5% for ulnar dimensions. Conclusion:The study demonstrated the high accuracy of the distal epiphyseal ends of the radius and ulna in identifying sex.

“…Indeed, the replacement of traditional postmortem techniques with CSI examination has been recommended by scientific, cultural, and humanitarian groups due to its non-invasiveness, digital nature, and 3D reconstruction opportunities (2). Literature data provide numerous evidences that CSI reconstruction is useful for the analysis of the neuronal morphology, bones, and teeth (3)(4)(5)(6)(7)(8). For instance, the possibility to estimate a person's age by assessment of dental pulp volume or sex by calculating long bone's metrical quantities has been documented (9)(10)(11)(12)(13).…”

The aim of the present paper is to determine the sex of the individual using three-dimensional geometric and inertial analyses of metatarsal bones. Metatarsals of 60 adult Chinese subjects of both sexes were scanned using Aquilion One 320 Slice CT Scanner. The three-dimensional models of the metatarsals were reconstructed, and thereafter, a novel software using the center of mass set as the origin and the three principal axes of inertia was employed for model alignment. Eight geometric and inertial variables were assessed: the bone length, bone width, bone height, surface-area-to-volume ratio, bone density, and principal moments of inertia around the x, y, and z axes. Furthermore, the discriminant functions were established using stepwise discriminant function analysis. A cross-validation procedure was performed to evaluate the discriminant accuracy of functions. The results indicated that inertial variables exhibit significant sexual dimorphism, especially principal moments of inertia around the z axis. The highest dimorphic values were found in the surface-area-to-volume ratio, principal moments of inertia around the z axis, and bone height. The accuracy rate of the discriminant functions for sex determination ranged from 88.3% to 98.3% (88.3%–98.3% cross-validated). The highest accuracy of function was established based on the third metatarsal bone. This study showed for the first time that the principal moment of inertia of the human bone may be successfully implemented for sex estimation. In conclusion, the sex of the individual can be accurately estimated using a combination of geometric and inertial variables of the metatarsal bones. The accuracy should be further confirmed in a larger sample size and be tested or independently developed for distinct population/age groups before the functions are widely applied in unidentified skeletons in forensic and bioarcheological contexts.

“…Researchers have explored the use of statistical analyses and set up sex assessment equations using different bones like the sternum, scapula, patella, metacarpals and phalanges (Franklin et al, 2012;El Morsi and Al Hawary. 2013;Torimitsu et al, 2016 andYasar et al, 2018).…”

“…Magnetic resonance imaging technique offers a way to examine all types of tissue with relatively low radiation effects (Yasar et al, 2018). So, the aim of the current work was to evaluate sexual difference of sacrum and coccyx using MRI image-based morphometric data to set up a discriminant equation for sex assessment in Egyptian population.…”
