The Role and Place of Thanatoradiological Studies in the Pathological Examination of Fetuses and Newborns.

Analysis of published data on the possibilities of using postmortem radiation studies in perinatology is carried out and the results of own thanatoradiological studies of the bodies of dead fetuses and newborns are presented. The possibilities of postmortem radiation studies for differential diagnosis of stillborn and deceased newborns, evaluation of the severity of maceration and the time of intrauterine fetal death, detection of pathological changes in the brain and spinal cord, respiratory and digestive organs, in the cardiovascular and urinary systems were demonstrated. It is concluded that postmortem CT has a high diagnostic efficiency in the study of the bone skeleton, free fluid accumulations in serous cavities and gas in the vessels and tissues of dead fetuses and deceased newborns. The advantage of postmortem MRI is more effective visualization of internal organs and soft tissues, which allows assessing their topography and size, as well as identifying a wide range of pathological changes. For a comprehensive objective analysis of the bodies of stillborn and deceased newborns, combined use of both imaging methods (CT and MRI) is required. At the same time, thanatoradiology should be used as a part of a comprehensive pathological study, but not as a substitute for traditional autopsy.
