Comparative radiologic identification with CT images of paranasal sinuses – development of a standardized approach
Publication date: Available online 3 September 2016 Source:Journal of Forensic Radiology and Imaging Author(s): Thomas D. Ruder, Cédric Brun, Angi M. Christensen, Michael J. Thali, Dominic Gascho, Wolf Schweitzer, Gary M. Hatch The routine use of computed tomography (CT) to forensic medicine allows for new methods of radiologic identification. Here we present a method to reconstruct a standardized CT image of the head for comparative identification: CT images are reconstructed in MPR along skeletal anatomical landmarks of the inner ear and the orbit. The key advantage of working with standardized images for ident...

White matter hyperintensities analysis by diffusion tensor images obtained from postmortem in cranium whole brain tissue
Conclusions We have demonstrated that in situ postmortem FA values at WMH are lower than NAWM, similar to in vivo data. This indicates that DTI obtained at a short postmortem interval from PM MRI could be used to understand in vivo MRI data. (Source: Journal of Forensic Radiology and Imaging)

“Assessment of Frontal Sinus Dimensions using CBCT to Determine Sexual Dimorphism amongst Egyptian Population”
Conclusion Frontal sinus examination is a valuable tool for personal identification and gender differentiation, Cone beam CT examination in addition to being a safe procedure with minimal radiation exposure, proved to be highly accurate in sinus imaging and provide valuable and precise information about frontal sinus and the whole skull. Limitations Frontal sinus identification requires comparison with previous antemortem image which is not routinely done in many countries. (Source: Journal of Forensic Radiology and Imaging)

Use of a low-cost three-dimensional gaming controller for forensic reconstruction of CT images
We present an approach that utilizes a 3D game controller as an input device in combination with a 3D/2D display technique to provide a more intuitive and efficient user interaction for PMCT visualization. An inexpensive off-the-shelf game controller was used as an input device that provides six degrees-of-freedom to create oblique image reconstructions and control a volume-rendering view. Two specific examples are described in which the system was valuable in presenting the critical pathology. (Source: Journal of Forensic Radiology and Imaging)

Denture marker with titanium number plates
This article describes the marking of dentures with patients social security number cut on the titanium plates positioned across the palatal surface of the denture that is either visualized through direct vision or with the radiographs. The social security numbers are internationally recognized and provide the required information obtained from the social security administration or unique identification authority.

The roles of X rays and other types of electromagnetic radiation in evaluating paintings for forgery and restoration
This article examines the roles of xrays and, to a lesser degree, gamma rays and beta particles in ruling out forgery and guiding the restoration of paintings. Of the 3 aforementioned EMR types, xrays have the largest role in painting authentication and restoration; much of this article is an overview of the different mechanisms by which xrays can be generated, as well as the information gleaned, from the different technologies in the forensic examination of paintings. Currently, the best method which uses EMR to examine paintings in 2 or 3D is optical coherence tomography (OCT). While OCT is not a widely known modality to...

Cardiothoracic ratio (CTR) measured on post-mortem computed tomography (PMCT) – Pre- and post-ventilation
Publication date: Available online 15 January 2016 Source:Journal of Forensic Radiology and Imaging Author(s): Pippa James, Bruno Morgan, Guy N Rutty, Alison Brough The cardiothoracic ratio (CTR) is commonly used as an indicator of cardiomegaly in clinical radiology. CTR is generally calculated using measurements from chest radiographs. More recently, a number of studies have used computed tomography (CT). This has not been attempted using with post-mortem ventilation, which would more closely mimic the inspiratory breath hold phase chest radiograph used for clinical CTR. The aim of this study was to determine ...

Artifactual aortic dissection as a result of post-mortem CT angiography
Publication date: Available online 22 January 2016 Source:Journal of Forensic Radiology and Imaging Author(s): Corey Thompson, Sarah Parsons, Chris O'Donnell An 82-year-old woman who died unexpectedly at home was admitted to our institute for investigation into her cause of death. Extensive subarachnoid hemorrhage was identified on the admission post-mortem computed tomography (PMCT) scan. Subsequent post-mortem computed tomography angiography (PMCTA) utilizing embalming principles and equipment identified leak of contrast from the right middle cerebral artery indicative of ruptured aneurysm and this was confirme...

Validation of post mortem dental CT for disaster victim identification
This study shows that visual comparison of PMCT images with AM dental radiographs is a reliable method for identification. Accuracy of identification using PMCT/AM dental radiographs was as high as in comparable studies using post mortem (PM) dental radiographs/AM dental radiographs. Raters with practical experience in forensic identification and experience with the imaging modality (in this case: dental PMCT) achieve higher accuracy than inexperienced raters. Match accuracy did not correlate with subjective confidence or number of concordant features. It is advised to work in teams rather than individually when dealing wi...

Biological profiling of Richard III using post-mortem computed tomography scanning
Publication date: Available online 15 January 2016 Source:Journal of Forensic Radiology and Imaging Author(s): A. Brough, B. Morgan, C. Robinson, J. Appleby, R. Buckley, G. Rutty In August 2012 a skeleton was excavated in Leicester that was subsequently identified as that of Richard III, the last King of England to die in battle. In addition to a traditional full osteological analysis, an independent osteological assessment was undertaken using post-mortem computed tomography (PMCT). This publication presents the methods that were used for the PMCT examination of the skeleton, the results achieved and a com...
