Abstract:
Despite the initial promises, less invasive autopsy by postmortem MRI has not gained widespread acceptance and is not yet used as a clinical tool. Current evidence on postmortem MRI is primarily limited to examination of fetal brain malformations. Large prospective studies funded by the UK Department of Health evaluating accuracy of postmortem MRI are now nearing completion. Less invasive autopsies may have a major effect in resurrecting autopsy rates; however, an evidence based and systematic approach towards less invasive autopsy process is mandatory to ensure postmortem data remains accurate and credible. This review summarises the current evidence, practical aspects and future directions for non-forensic less invasive autopsy in fetuses, newborns and children. A joint effort between clinicians, radiologists, pathologists, parent groups and funding bodies is essential for the successful implementation of less invasive autopsy in the UK.
Insights
Postmortem MRI offers a less invasive autopsy alternative, but requires more evidence for clinical use. Further research and collaboration are essential for its successful implementation in pediatric cases.
Area of Science:
- Medical Imaging
- Pathology
- Pediatrics
Background:
- Less invasive autopsy using postmortem MRI shows promise but lacks widespread clinical acceptance.
- Current evidence is mainly focused on fetal brain malformations, limiting broader application.
- Rising autopsy rates are a potential benefit, but data accuracy and credibility are paramount.
Purpose of the Study:
- To review current evidence on less invasive autopsy via postmortem MRI.
- To discuss practical aspects and future directions for non-forensic applications in fetuses, newborns, and children.
- To highlight the need for a systematic, evidence-based approach to ensure data integrity.
Main Methods:
- Review of existing literature on postmortem MRI for less invasive autopsy.
- Analysis of prospective studies evaluating the accuracy of postmortem MRI.
- Synthesis of practical considerations for implementation in pediatric settings.
Main Results:
- Postmortem MRI is not yet a widely accepted clinical tool despite initial promise.
- Large prospective studies are nearing completion, which may provide crucial accuracy data.
- Evidence base for less invasive autopsy in fetuses, newborns, and children is still developing.
Conclusions:
- Successful implementation of less invasive autopsy requires a multidisciplinary approach involving clinicians, radiologists, pathologists, and parent groups.
- An evidence-based and systematic process is mandatory to maintain the accuracy and credibility of postmortem MRI data.
- Further research and validation are needed to integrate postmortem MRI into routine pediatric autopsy practices.
