Intracranial cavity volumes: a new method and its potential applications
Neuropathology and Applied Neurobiology
|January 1, 1984
Summary
A new autopsy method uses polyurethane casts to measure cranial cavity volume. This technique accurately determines potential intracranial space, aiding in diagnosing brain pathologies like atrophy or swelling.
Area of Science:
- Neuropathology
- Forensic Medicine
- Anatomical Measurement
Background:
- Brain weight and volume variations can indicate disease.
- Relating these to intracranial volume provides more diagnostic value.
- Potential intracranial space (PIC) is a key derived parameter.
Purpose of the Study:
- To introduce a reliable autopsy method for determining intracranial volume.
- To establish a practical technique for measuring potential intracranial space.
Main Methods:
- Development of a polyurethane casting technique for cranial cavities.
- Casts produced within 20 minutes with minimal changes to autopsy procedures.
- Validation through duplicate casts in 27 cases, showing <2% error.
Main Results:
- The polyurethane casting method is rapid and reproducible.
- Duplicate casts demonstrated high accuracy (<2% error).
- The method allows for precise determination of intracranial volume and dimensions.
Conclusions:
- This technique offers a satisfactory solution for routine autopsy application.
- Accurate measurement of potential intracranial space aids in diagnosing cerebral atrophy, space-occupying lesions, and brain swelling.
