•CT has comparable accuracy to conventional radiography for dental profiling.•Dental CT is complementary to radiography for age estimation in modern populations.•Ethical concerns regarding CT in the living remain an important consideration.
Introduction: Stature estimation of human skeletal remains is important in medico-legal and forensic anthropology to personal identification. Several investigations have been carried out to estimating the height using the long bones. This study aimed was prediction the height of Iranian people based on the maximum length of femur and tibia by application of X-Ray method. Methods: This cross-sectional study was conducted in the radiology department of Baqiyatallah Hospital of Tehran, Iran between 2017 and 2018. The number of 166 adult women and men were investigated during the study period. Maximum lengths of the tibia and femur bones were measured on the X-Ray images. In the following, the data were analyzed by SPSS (ver. 22). Results: The results showed that there was a correlation between the stature and both of the femur and tibia lengths in the men and women (P-value <0.001). However, the highest values of correlation coefficient (R) were detected between the stature and lengths of the men's tibia (R = 0.838) and femur (R = 0.815) and lowest values were identified in the tibia (R = 0.467) and femur(R = 0.431) lengths of the women, respectively. The lowest value for standard error of the estimation (SEE) and the highest value for the coefficient of determination (R-2) were observed in multiple regression equation derived from the lengths of the men's femur and tibia (R-2 =0.736 and SEE = 5.64). Conclusion: Data confirmed that lengths of the tibia and femur of the men yield the best results in terms of the accuracy of the stature estimation in Iranian population.
This pictorial essay describes the use and value of post mortem computed tomography (PMCT) in imaging potential complications related to cardiopulmonary resuscitation and those related to commonly used pre-hospital medical resuscitation devices.
At the Zurich Institute of Forensic Medicine, post-mortem computed tomography (PMCT) has an important role. During an autopsy, access to the PMCT images can be important to localize findings. We present an approach to overcome the limitations of current systems for displaying medical image data during autopsy. The presented system uses augmented reality to display DICOM image stacks with basic functionality. In addition, we report the first test of the system during autopsy.
