What Is Postmortem CT?
Postmortem CT, also called PMCT or postmortem computed tomography, is an advanced forensic imaging tool used to support death investigation, documentation, and case review.
Postmortem CT, commonly referred to as PMCT, is the use of computed tomography after death to create detailed cross-sectional images of the body. In modern death investigation, PMCT can help medical examiner offices, coroner offices, forensic pathologists, and forensic radiologists evaluate injuries, document findings, and better understand the circumstances surrounding a death.
What Does Postmortem CT Mean?
Postmortem CT stands for postmortem computed tomography. “Postmortem” means after death, and “computed tomography” refers to CT imaging, which uses X-rays and computer processing to create detailed images of internal structures.
In a forensic setting, PMCT is used to examine the body after death. These images may show skeletal injuries, foreign objects, gas patterns, medical devices, trauma-related findings, and other features that can assist with death investigation.
How Is PMCT Used in Death Investigation?
PMCT is used as part of a broader forensic investigation. It does not replace the judgment of the forensic pathologist, medical examiner, coroner, or investigative team. Instead, it provides additional visual information that can support case triage, documentation, consultation, and reporting.
In many cases, PMCT can help identify findings that may be difficult to fully appreciate externally. It may also help guide the next steps in an investigation, including whether further examination, additional testing, or targeted evaluation may be needed.
What Can Postmortem CT Show?
Postmortem CT can be especially useful for evaluating skeletal trauma, ballistic injuries, sharp force trauma, blunt force trauma, foreign bodies, medical implants, and certain internal findings. It can also provide a permanent digital record of the body at the time of imaging.
Common PMCT Applications
- Documentation of fractures and skeletal trauma
- Evaluation of firearm and projectile-related injuries
- Identification of foreign bodies or retained medical devices
- Support for medical examiner and coroner case triage
- Creation of a permanent imaging record for later review
- Use in consultation, education, and courtroom presentation
Why Is PMCT Important for Medical Examiner and Coroner Offices?
Medical examiner offices and coroner offices often face increasing caseloads, limited staffing, and a need for clear documentation. PMCT can support these agencies by adding a powerful imaging-based layer to the death investigation process.
For agencies building or expanding a forensic imaging program, PMCT may improve workflow, support collaboration, and provide imaging information that can be reviewed by forensic radiology specialists.
Who Interprets Postmortem CT Scans?
Postmortem CT scans are typically reviewed by radiologists with expertise in forensic radiology and postmortem imaging. Interpretation of PMCT requires knowledge of both imaging findings and postmortem changes. This is different from routine clinical radiology, where imaging is performed on living patients.
Forensic radiology is a specialized field focused on the use of imaging in legal, investigative, and medicolegal contexts. PMCT is one of the most important tools within modern forensic imaging.
Does PMCT Replace an Autopsy?
PMCT does not automatically replace a traditional autopsy. In many death investigations, it works alongside external examination, investigative history, toxicology, autopsy, and other forensic methods.
The role of PMCT depends on the case, the jurisdiction, the agency’s workflow, and the questions being asked. In some situations, PMCT may help guide a targeted examination. In others, it may provide documentation or supplemental findings that strengthen the overall investigation.
How PMCT Supports Forensic Imaging Programs
A successful PMCT program requires more than access to a CT scanner. Agencies must consider scanning protocols, image transfer, reporting workflow, radiology interpretation, forensic pathology collaboration, staff training, and long-term quality assurance.
Forensic Radiology Group supports agencies with forensic imaging interpretation, PMCT education, implementation guidance, and consultation for medical examiner and coroner offices interested in developing or improving postmortem imaging workflows.
Need Support With PMCT or Forensic Imaging?
Forensic Radiology Group provides specialized forensic imaging services, education, and implementation support for agencies working with postmortem CT and death investigation.

What is PMCT?
PMCT stands for postmortem computed tomography. It is CT imaging performed after death to help evaluate and document internal findings.
Is postmortem CT the same as forensic imaging?
PMCT is one type of forensic imaging. Forensic imaging may also include X-ray, CT angiography, 3D reconstruction, and other imaging techniques used in medicolegal investigation.
Who uses postmortem CT?
PMCT may be used by medical examiner offices, coroner offices, forensic pathologists, forensic radiologists, law enforcement agencies, and death investigation teams.
Can PMCT help with death investigation?
Yes. PMCT can provide important visual documentation and may help identify injuries, foreign bodies, medical devices, and other findings relevant to a death investigation.
Does every medical examiner office use PMCT?
No. PMCT availability varies by jurisdiction, resources, workflow, and access to imaging equipment and forensic radiology interpretation.
