A machine learning model was developed to classify chest radiographs, achieving 94.6% accuracy in identifying abnormalities. This AI tool can help prioritize radiologist workload for improved efficiency.

Area of Science:

  • Artificial Intelligence in Medical Imaging
  • Machine Learning for Diagnostic Support

Background:

  • Chest radiography interpretation is crucial for diagnosing various conditions.
  • Clinician workload can be optimized through efficient reporting prioritization.

Purpose of the Study:

  • To develop a machine learning (ML) model for binary classification of chest radiography abnormalities.
  • To create a retrospective tool for guiding clinician reporting prioritization.

Main Methods:

  • Utilized Tensorflow and the Inception deep convolutional neural network (CNN).
  • Retrained the final layer for binary normality classification on public datasets.
  • Trained on 47,644 images and validated on 5,505 unseen radiographs.

Main Results:

  • Achieved a final model accuracy of 94.6% on the unseen testing subset.
  • Reported sensitivity of 94.6% and specificity of 93.4%.
  • Obtained a positive predictive value (PPV) of 99.8% and an area under the curve (AUC) of 0.98.

Conclusions:

  • Demonstrated the successful application of an ML-based approach for chest radiograph classification.
  • The model shows potential for optimizing clinician workload in real-world settings.
