Area of Science:

  • Forensic Pathology
  • Neuropathology
  • Medical Imaging

Background:

  • Current brain edema evaluation relies on subjective macroscopic assessment by pathologists.
  • Histological verification, the gold standard, is time-consuming and labor-intensive.

Purpose of the Study:

  • To develop a rapid, objective mathematical model for evaluating brain edema during autopsy.
  • To establish a reliable method for detecting cerebral edema using morphometric parameters.

Main Methods:

  • A cohort study involving 110 subjects was conducted.
  • Morphometric parameters including cranial cavity diameters and brain weight were measured.
  • A mathematical algorithm was developed to calculate a coefficient (ε) for edema detection.

Main Results:

  • The formula for coefficient ε is (5.79 x longitudinal distance x transverse distance)/brain weight.
  • An ε value less than 0.9484 indicates cerebral edema with 98.5% reliability.
  • Average brain density differs significantly between non-edematous (0.967 g/ml) and edematous (1.148 g/ml) brains.

Conclusions:

  • The developed mathematical model provides a rapid and objective method for diagnosing brain edema at autopsy.
  • This approach reduces reliance on subjective pathological assessments.
  • The coefficient ε serves as a reliable indicator for the presence of cerebral edema.
