“…However, the 95% confidence interval for the measurement difference between CT and dry bone measurements of the lower limb and foot was approximately +/-5 mm [2], which is considerably larger than the generally accepted level in anthropology. The range of measurement error obtained by Verhoff et al [19] is between 1 and 2 mm; a result that is more acceptable within forensic applications. Besides validating the measurement error between dry and CT images for the areas that have previously been evaluated, measurement errors need to be recorded for the entire skeleton as almost all elements are used in estimation techniques for ancestry, sex, stature and age.…”

Forensic pathologists commonly use computed tomography (CT) images to assist in determining the cause and manner of death as well as for mass disaster operations.Even though the design of the CT machine does not inherently produce distortion, most techniques within anthropology rely on metric variables, thus concern exists regarding the accuracy of CT images reflecting an object's true dimensions. Numerous researchers have attempted to validate the use of CT images, however the comparisons have only been conducted on limited elements and/or comparisons were between measurements taken from a dry element and measurements taken from the 3D-CT image of the same dry element.A full-body CT scan was performed prior to autopsy at the Office of the Chief Medical Examiner for the State of Maryland. Following autopsy, the remains were processed to remove all soft tissues and the skeletal elements were subject to an additional CT scan. Percent differences and Bland-Altman plots were used to assess the accuracy between osteometric variables obtained from the dry skeletal elements and from CT images with and without soft tissues. An additional seven crania were scanned, measured by three observers, and the reliability was evaluated by technical error of measurement (TEM) and relative technical error of measurement (%TEM).Average percent differences between the measurements obtained from the three data sources ranged from 1.4% to 2.9%. Bland-Altman plots illustrated the two sets of measurements were generally within 2mm for each comparison between data sources. Intra-observer TEM and %TEM for three observers and all craniometric variables ranged between 0.46 mm and 0.77 mm and 0.56% and 1.06%, respectively. The three-way interobserver TEM and %TEM for craniometric variables was 2.6 mm and 2.26%, respectively. Variables that yielded high error rates were orbital height, orbital breadth, inter-orbital breadth and parietal chord. Overall, minimal differences were found among the data sources and high accuracy was noted between the observers, which prove CT images are an acceptable source to collect osteometric variables.

“…Culbert and Law (1927) Currently there is no agreed protocol to create a biological profile from PMCT examination of juveniles or adults. The literature presents a number of studies using single osteological or odontological assessments to assist with biological profiling (41)(42)(43)(44), but a system compiling all of these assessments into a single protocol had yet to be published or presented. In addition, the majority of these studies have been conducted using an adult cohort, with very few extending to the juvenile age range.…”

The future of pediatric and perinatal postmortem imaging

et al. 2015

The field and applications of post-mortem imaging are exponentially growing. Its potential to identify the cause of death in trauma and ballistic cases is now properly documented, as well as its use in drug mules identification. In pediatric and perinatal practice, large significant series are less available, except for MRI and central nervous system analysis where scientific evidence is now robust. In this review, after a short historical review and analysis of current problems and challenges, we will try to depict the way we see the future of this sub-specialty of post-mortem cross sectional, including in the scope all specific situations : terminations of pregnancy, intrauterine death, sudden unexpected infant death, and identification issues.
