However, owing to the high number of cases and the limited availability of skilled practitioners, the need to streamline the diagnostic process has spurred the advancement of automated solutions. These solutions leverage deep learning methodologies to potentially automate diagnoses by analyzing postmortem CT data. Here, we show how deep learning techniques enable segmentation and volume evaluation to be concurrently performed for six basic thoracic and abdominal organs in postmortem CT data: the heart, lungs, liver, spleen, kidneys, and urinary bladder.

For adolescents and young adults, methods often rely on bone end closures. Post-mortem computed tomography (PMCT) is a reliable tool for forensic age estimation in DVI cases. This study aimed to develop reference material for estimating the age of deceased adolescents and young adults using PMCT of the knee and clavicle in a Danish population. Results from the knee and clavicle were compared, and decision trees were created for final age estimates based on various bone combinations. The study included 221 individuals (57 females, 164 males) aged 10-25 years who underwent PMCT before medico-legal autopsy. Using the staging method by Schmeling et al. and Kellinghaus et al. ossification in the distal femoral, proximal tibial, proximal fibular, and medial clavicular epiphyses were evaluated. Large age intervals were observed for all bone stages, except for the earliest and latest clavicle stages. The clavicle stage distribution correlated well with chronological age, and reference values were consistent with previous studies. Individuals of younger age exhibited higher knee-bone stages than clavicle stages. Decision trees indicated that age intervals could be narrowed by combining clavicle stages with femur and fibula stages, though caution is required when intervals are too narrow. This study provides reference material for forensic age estimation in adolescents and young adults using PMCT of the knee and clavicle, relevant in DVI cases where limited body parts are available for analysis.</div></div>","PeriodicalId":40763,"journal":{"name":"Forensic Imaging","volume":"42 ","pages":"Article 200638"},"PeriodicalIF":0.8,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144203060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional morphometric techniques, involving caliper-based measurements, are often labor-intensive and time-consuming. In contrast, the geometric morphometric method (GMM) offers a more efficient approach, integrating qualitative and quantitative assessments of biological forms based on precise geometric characterizations of their shape. This study aimed to assess sexual dimorphism of the Atlas (C1) bone on lateral cervical radiographs using GMM. A cross-sectional design was employed, utilizinglateral cervical radiographs from a sample of 413 individuals, including 208 males and 205 females, age ranged between 35 and 45 years old. Six 2D landmarks were identified and marked on the digitalized radiographs using TPSDig2 (Version 2.31) software. GMM analysis conducted by MorphoJ software. Eight principal components (PC) accounted for 100 % of the shape variability produced. Procrustes ANOVA showed that centroid size and shape were significantly different between different sexes. Discriminant function analysis (DFA) revealed a correct classification rate for 87.9 % of cases, with an identification accuracy of 87.0 % for males and 88.8 % for females. There were significant differences among males and females in the height of the C1 vertebral body with <em>p</em> < 0.05 via independent t-test. In conclusion, there was a significant sexual dimorphism of the C1 vertebra by GMM, which could serve as an alternative method in physical anthropology and forensic medicine.</div></div>","PeriodicalId":40763,"journal":{"name":"Forensic Imaging","volume":"41 ","pages":"Article 200637"},"PeriodicalIF":0.8,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143895414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
