Summary
This study introduces an automated system for nasopharyngeal carcinoma (NPC) T staging using multi-modal learning. The AI approach integrates MRI images and reports for faster, more accurate staging, improving clinical decision-making.
Area of Science:
- Oncology
- Medical Imaging
- Artificial Intelligence
Background:
- Accurate T staging of nasopharyngeal carcinoma (NPC) is critical for personalized treatment but faces challenges in time consumption and observer variability.
- Developing an efficient, automated T staging system is essential for optimizing clinical workflows and patient care.
Purpose of the Study:
- To develop an efficient and automated T staging system for nasopharyngeal carcinoma (NPC).
- To improve the accuracy and consistency of NPC T staging through a multi-modal learning approach.
Main Methods:
- A multi-modal learning framework integrating MRI images and reports from 609 NPC patients.
- Utilized Vision Transformer (ViT) for visual features, BERT for text features, and Q-Former for data fusion.
- Employed a hierarchical classification strategy (DeepTree) for complex staging challenges.
Main Results:
- The multi-modal approach integrating images and text via Q-Former significantly outperformed single-modality methods.
- The IT-DTM-BLIP2 model achieved an accuracy of 0.787 and AUC values of 0.815 (T2 vs. T3/T4) and 0.876 (T3 vs. T4).
Conclusions:
- The developed multi-modal approach provides a robust automated solution for NPC T staging, eliminating the need for manual tumor delineation.
- This automated system streamlines clinical workflows, reduces subjectivity, and supports decision-making for improved efficiency and consistency.
