AbstractBackground: The Postmortem in Computed tomography (PMCT) had been started from since 1990. PMCT advantages are more relevant in full-body examination (FBE) through scan is quite helpful to assess the whole body scan with clear evidence and computed recorded data. Material and methods: Here trying to justify the PMCT application, analysis and its interpretation in cadaveric, CT examination test before autopsy test to know the causes of death (COD), cause of injury (COI) and other additional information related to image study. Inclusion Criteria: The original contribution selected form (1990 to 2019) is included in study. Exclusion Criteria: An irrelevant study or any case study subject excluded from this study. Statistical analysis: Here simple statistics used from the available database for interpretation. Results: PMCT in analysis given more than (70-90%) better picture than the autopsy test. It clearly analyzed the cause of death (COD), manners of injury (MOI), and personal of identification (POI) through the postmortem examination (PME) and its development in the field of forensic medicine and toxicological research (FMTR). Conclusion: PMCT technology newly added and highly recommendable for correct information through their slice images. So many types of variables (TOVs) may easily compare and predict through the different informative slice images (DISIs) to use the accurate application on forensic medicine and toxicological angle.
