Pulmonary thromboembolism (PTE), which is caused by detachment of venous thrombosis, is a common cause of sudden death in forensic practice. In the cases which die of PTE after trauma or die of PTE during non-thrombosis disease hospitalization, forensic pathologists are required to analyze the time sequence between trauma or medical practice and venous thrombosis, and then analyze their causal relationship. This review summarizes the history of thrombus age estimation and recent advances in forensic medicine, and then gives a brief outlook for future research to provide reference for forensic identification of PTE and guide follow-up studies.

Individual identification by measuring the human skeleton is an important research in the field of forensic anthropology. Computed tomography (CT) technology can provide high-resolution image of skeleton. Skeleton image can be reformed by software in the post-processing workstation. Different skeleton measurement indexes of anthropology, such as diameter, angle, area and volume, can be measured on section and reformative images. Measurement process is barely affected by human factors. This paper reviews the literatures at home and abroad about the application of measuring skeleton by CT in forensic anthropology research for individual identification in four aspects, including sex determination, height infer, facial soft tissue thickness measurement and age estimation. The major technology and the application of CT in forensic anthropology research are compared and discussed, respectively.

The traditional methods of skeletal age estimation mainly include Numeration, Atlas, and Counting scores. In recent years, other new methods were proposed by several scholars. Utilizing image logical characteristics of X-ray film to extrapolate skeletal age is a key means by present forensic medicine workers in evaluating skeletal age. However, there exist some variations when we present the conclusion of skeletal age as an "evidence" directly to the Justice Trial Authority. In order to enhance the accuracy of skeletal age determination, further investigation for appropriate methodology should be undertaken. After a collective study of pertinent domestic and international literatures, we present this review of the research and advancement on skeletal age evaluation methods of X-ray film.
