Area of Science:

  • Surgical technology
  • Medical imaging
  • Artificial intelligence in medicine

Background:

  • Accurate intraoperative tissue discrimination is crucial for safe surgical procedures.
  • Current methods rely on visual cues which can be ambiguous.
  • Enhancing surgical vision is a key area of research for improving patient outcomes.

Purpose of the Study:

  • To assess the feasibility of using multispectral imaging (MSI) combined with deep learning for automated identification of normal human head and neck tissues.
  • To develop and test a novel MSI system adapted for surgical applications.
  • To compare the performance of MSI-based deep learning models against traditional white-light imaging and human expert performance.

Main Methods:

  • A novel MSI system was constructed and minimally adapted from a digital operating microscope.
  • Multispectral images of human cadaveric head and neck tissues were captured under various lighting conditions.
  • Two deep learning models (ARRInet-M for MSI and ARRInet-W for white-light) were trained and tested; performance was compared to otolaryngology residents.

Main Results:

  • The MSI-based deep learning model (ARRInet-M) achieved 81.8% accuracy in tissue identification, significantly outperforming the white-light model (ARRInet-W) at 45.5% and surgical residents at 69.7%.
  • The developed MSI system demonstrated feasibility for surgical integration.
  • Challenges in discriminating specific tissues like parotid vs. fat and blood vessels vs. nerve were noted.

Conclusions:

  • A deep learning model utilizing multispectral imaging significantly enhances the ability to classify normal human head and neck tissues ex vivo.
  • MSI technology shows promise for augmenting surgeons' intraoperative tissue identification capabilities.
  • This approach can potentially improve surgical safety and precision in head and neck procedures.
