Working Paper

Background; Sex identification of unknown skeletal human remains is of great importance in establishing identity and individuality. In adults, hip bone is the most reliable sex indicator because of its sexual dimorphism. Each population should have its own specific standards of identification. Objectives; develop a logistic regression formula for adult sex identification using three-dimensional computed tomography (3D-CT) of the pelvis, and assessment of its validity in sex determination among a sample of Egyptian population at Suez Canal region. Materials and Methods; 141 pelvi-abdominal CT images (free of any pelvic orthopaedic disorder) were included; they were reconstructed to produce 3D-CT pelvic images; they were divided into calibration group (47 male & 47 female) and test group (47 CT images their sex is unknown to the observers), twenty radiometric variables were measured for the calibration groups. A logit response formula for sex prediction was developed and applied on the test group for sex prediction. Results; the logit response formula for the test sample showed sensitivity, specificity and overall accuracy 100%. Conclusion; Proposed method represent a quick and reliable metric method in establishing sex from the pelvis Keywords: Forensic anthropology, Sex identification, 3D-CT pelvic images.
