This study developed an expert system to automatically create optimal GDC selection programs for intracranial aneurysm embolization. The system uses a case base, data mining, and DEA to guide GDC device selection.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Artificial Intelligence

Background:

  • Intracranial aneurysms require precise treatment, often involving embolization with Guglielmi Detachable Coils (GDCs).
  • Optimal GDC selection is crucial for successful embolization but can be complex and experience-dependent.

Purpose of the Study:

  • To develop an automated expert system for generating optimal GDC selection programs for intracranial aneurysm embolization.
  • To leverage artificial intelligence and data analysis to assist in neurovascular procedures.

Main Methods:

  • Collected data from 20 intracranial aneurysm embolization cases using GDC dense packing.
  • Developed an expert system incorporating a case base, a mathematical model (multi-layer perceptron with polyhedrons), and data envelopment analysis (DEA).

  • Utilized data mining techniques to simulate expert decision-making in GDC selection.

    • Main Results:

    • The expert system successfully generated candidate GDC selection programs based on user-inputted aneurysm parameters (volume, location, diameter).
    • Inputting aneurysm volume, location, maximum transverse diameter, and maximum length diameter yielded proposed GDC selection programs.

    Conclusions:

    • An expert system combining a case base, data mining, and DEA can automate optimal GDC selection for intracranial aneurysm embolization.
    • The clinical utility of this automated system requires further investigation and validation.
