Area of Science:

  • Forensic pathology
  • Radiology
  • Postmortem imaging

Background:

  • Postmortem computed tomography (PMCT) visualizes sequential brain changes over time.
  • Assessing brain rigidity is crucial for macroscopic examination during autopsy.

Purpose of the Study:

  • Investigate the relationship between brain rigidity and advanced postmortem changes on PMCT.
  • Evaluate PMCT findings as indicators of macroscopic brain examination success.

Main Methods:

  • Analysis of 149 cases using PMCT prior to autopsy.
  • Classification of advanced postmortem changes into four stages.
  • Correlation of PMCT findings with macroscopic brain examination validity.

Main Results:

  • Postmortem changes, staged via PMCT, correlate with brain fragility.
  • Advanced PMCT findings indicate reduced brain rigidity.
  • PMCT findings can predict the success of macroscopic brain examination.

Conclusions:

  • PMCT is a valuable tool for assessing postmortem brain changes.
  • PMCT findings can guide forensic pathologists in handling fragile brains.
  • Utilizing PMCT enhances the quality and reliability of autopsy procedures.
