“…However, Franklin et al [32], stated that, in the absence of such research collections, medical scans and measurements on living individuals offer an appropriate and reliable source of contemporary population-specific data from which forensic standards are being formulated. Also, Sakuma et al [33], directly measured skull lengths and subsequently re-measured the skulls using reconstructed 3D CT images. They reported no significant differences between the actual measurements and the measurements based on 3D CT images.…”

“…However, special CT-skills may be necessary to achieve reliable results, when working with 3D CT imaging. Sakuma et al [34] measured skull lengths with calipers and subsequently re-measured the skulls using reconstructed 3D CT images in our department. They reported no significant difference between the actual measurements and the measurements based on 3D CT images.…”

This study assessed the correlation between stature and scapular measurements in a Japanese population, using three-dimensional (3D) computed tomographic (CT) images, and derived regression equations for predicting stature. A total of 194 cadavers (100 males 94 females) underwent postmortem CT (PMCT) and subsequent forensic autopsy in our department between May 2011 and April 2014. Left and right longitudinal scapular lengths (LLSL and RLSL, respectively) and left and right transverse scapular lengths (LTSL and RTSL, respectively) were measured on 3D CT reconstructed images that extracted only scapular data. The correlation between stature and each of the scapular measurements were analyzed using Pearson product-moment correlation coefficients. The four variables correlated significantly with stature, regardless of sex. The LLSL measurement had the lowest standard error of estimation value among all subjects (4.22 cm) and among all females (4.37 cm), whereas the RLSL measurement had the lowest standard error of estimation value among all males (3.75 cm). The results of this study indicate that scapular measurements may be useful for the forensic estimation of the stature of Japanese individuals, particularly in cases where better predictors, such as long bone lengths, are unavailable.

“…Furthermore, CT can be used for 3D reconstructions which in turn serve as comparative material for the superimposition tests in unidentified cases [9]. The 3D reconstructions of the skull performed as part of the forensic postmortem examination were previously described [3, 10] and its use as a valuable screening tool in identification procedures was suggested [10].…”

The conclusive role of postmortem computed tomography (CT) of the skull and computer-assisted superimposition in identification of an unknown body

et al. 2012

Computed tomography is commonly used in modern medicine, and thus, it is often helpful for medicolegal purposes, especially as part of the antemortem record. The application of postmortem computed tomography and 3D reconstruction of the skull in challenging cases is reported, and its valuable contribution to positive identification is discussed. This paper presents a case in which the body of an unknown individual is identified. Positive identification had not been possible despite a multidisciplinary examination. The postmortem use of computerized tomography and 3D reconstruction of the skull followed by the comparison of individual morphological characteristics of the viscerocranium showed the concordant points between the deceased and a missing person. Finally, superimposition using a 3D-reconstructed skull instead of the skeletonized skull demonstrated an adequate degree of morphological consistency in the facial images of the analyzed individuals that lead to positive identification. It was concluded that where other methods of personal identification had failed, the use of postmortem computed tomography had proved to be instrumental in the positive identification of the deceased.
