Abstract:
Postmortem imaging techniques, especially postmortem computed tomography, have become integral tools in forensic investigations. Multiphase postmortem computed tomography angiography (MPMCTA) visualizes the vascular system in detail and makes it possible to evaluate the perfusion of even the smallest vessels. Although the technique has been well described for adults, no pediatric cases have been reported and no pediatric protocol has been established for this type of investigation. We present the case a 7-year-old child for which we used a previously described MPMCTA protocol and adapted values of perfusion, with the same technical equipment as for adult cases. Our main objective was to propose a perfusion protocol adapted for the investigation of infants and children. Moreover, we discuss both the difficulties that we encountered and possible ways to further improve the investigation of pediatric cases by MPMCTA.
Insights
This study introduces a new multiphase postmortem computed tomography angiography (MPMCTA) protocol for pediatric cases. The adapted protocol allows detailed vascular visualization in children, aiding forensic investigations.
Area of Science:
- Forensic Radiology
- Pediatric Imaging
- Vascular Imaging
Background:
- Postmortem imaging, particularly postmortem computed tomography (PMCT), is crucial in forensic investigations.
- Multiphase postmortem computed tomography angiography (MPMCTA) offers detailed visualization of the vascular system, including small vessels.
- Existing MPMCTA protocols are established for adults, with no specific guidelines for pediatric applications.
Observation:
- A 7-year-old child underwent MPMCTA using adapted perfusion values from an adult protocol.
- The same technical equipment used for adult cases was employed.
- This case represents the first reported pediatric application of MPMCTA.
Findings:
- The adapted MPMCTA protocol successfully visualized the pediatric vascular system.
- Specific perfusion values were adjusted for the pediatric case.
- The study identified challenges and potential improvements for pediatric MPMCTA.
Implications:
- This work proposes a novel, adapted MPMCTA perfusion protocol for infants and children.
- The findings aim to standardize pediatric postmortem vascular imaging in forensic science.
- Further research can refine MPMCTA techniques for improved pediatric forensic investigations.
