Area of Science:

  • Radiology and Medical Imaging
  • Artificial Intelligence in Healthcare
  • Natural Language Processing (NLP)

Background:

  • Effective imaging examination selection and protocoling are crucial for accurate diagnosis and minimizing radiation exposure.
  • Current pre-imaging radiology workflows can be inefficient, impacting patient care and resource allocation.
  • Automating the review of radiology examination requests presents an opportunity to enhance workflow efficiency.

Purpose of the Study:

  • To develop and evaluate an automated model for revising radiology examination requests using NLP.
  • To improve the efficiency of the pre-imaging radiology workflow.
  • To identify radiology orders that require additional review through an automated system.

Main Methods:

  • Extracted Musculoskeletal (MSK) magnetic resonance imaging (MRI) exam orders from a radiology information system.
  • Utilized a pretrained transformer model (DistilBERT) for vector representation of free text in exam orders.
  • Trained a logistic regression classifier to identify orders necessitating further review.

Main Results:

  • The automated model achieved an accuracy of 83% in identifying radiology orders requiring additional review.
  • The model demonstrated a strong performance with an area under the curve (AUC) of 0.87.
  • The NLP-based approach effectively processed and analyzed free-text radiology orders.

Conclusions:

  • An automated NLP model can significantly improve the efficiency of radiology examination request revision.
  • The developed model shows promise for enhancing the pre-imaging workflow by accurately flagging orders for review.
  • This AI-driven approach has the potential to optimize radiology resource utilization and patient management.
