Deep learning models can automate histological section analysis in distraction osteogenesis, reducing manual effort. The study shows reliable segmentation of fibrous interzone and microcolumn formation zones, supporting objective histological assessment.

Area of Science:

  • Biomedical Engineering
  • Histology
  • Artificial Intelligence

Background:

  • Automated histological analysis in distraction osteogenesis can improve efficiency and reduce subjectivity.
  • Histological assessment is crucial for understanding bone healing processes.

Purpose of the Study:

  • To develop and evaluate a deep learning model for segmenting key tissue zones in rat tibial distraction osteogenesis.
  • To assess the model's performance in identifying fibrous interzone (FIZ), microcolumn formation zone (MCF), and remodeling zone (RM).

Main Methods:

  • A 2D nnU-Net model was trained to segment histological sections stained with hematoxylin and eosin (H&E).
  • The model segmented three distinct tissue zones: FIZ, MCF, and RM.
  • Performance was evaluated using five-fold cross-validation and Dice loss metrics.

Main Results:

  • The nnU-Net model achieved reliable segmentation performance for the FIZ and MCF.
  • The RM zone presented challenges due to its low frequency, weak boundaries, and morphological variability.
  • The study demonstrated a proof of principle for deep learning in histological zone segmentation.

Conclusions:

  • Deep learning offers a promising approach for objective and scalable histological analysis in distraction osteogenesis.
  • Further model refinement is needed to improve segmentation accuracy for challenging regions like the RM.
