Area of Science:

  • Artificial Intelligence in Medicine
  • Natural Language Processing
  • Radiology Informatics

Background:

  • Communication gaps persist between radiologists and referring physicians regarding diagnostic certainty.
  • Current methods for assessing certainty in radiology reports are insufficient for precise communication.

Purpose of the Study:

  • To explore deep learning-based bidirectional contextual language models for automatically assessing diagnostic certainty in radiology reports.
  • To enhance the precision of communication between radiologists and referring physicians.

Main Methods:

  • A dataset of 594 head MR imaging reports was randomly sampled.
  • Three radiologists annotated 2352 sentences from the Impression section into four certainty categories.
  • A natural language processing system using bidirectional encoder representations from transformers (BERT) was developed and validated.

Main Results:

  • The biomedical variant (BioBERT) achieved the highest area under the curve (0.931) on validation data.
  • All three BERT models demonstrated high macro-average specificity (93.13%-93.65%).
  • BioBERT showed strong generalizability on heldout test data with an area under the curve of 0.93.

Conclusions:

  • A deep transfer learning model can reliably assess the level of uncertainty communicated in radiology reports.
  • AI-powered analysis of radiology reports can significantly improve diagnostic communication accuracy.
