Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Parasitology

Background:

  • Alveolar echinococcosis (AE) requires early detection for effective treatment.
  • Accurate differentiation of liver conditions like tumors and AE is clinically significant.
  • Non-contrast CT imaging offers accessibility and safety advantages over contrast-enhanced methods.

Purpose of the Study:

  • To develop and evaluate an automated method for classifying liver conditions using non-contrast CT images.
  • To differentiate between healthy liver, AE, and tumor cases.
  • To assess the performance of a two-stage deep learning approach for liver disease diagnosis.

Main Methods:

  • An automated liver region detection using Region-based Convolutional Neural Networks (RCNN).
  • A Convolutional Neural Network (CNN) based classification framework for disease differentiation.
  • Utilized a dataset of over 27,000 thorax-abdominal CT images from 233 patients.

Main Results:

  • Achieved 0.936 accuracy for 2-class (healthy vs. non-healthy) classification.
  • Obtained 0.863 accuracy for 3-class (AE, tumor, healthy) classification.
  • Demonstrated the effectiveness of the two-stage classification strategy.

Conclusions:

  • The proposed framework offers a fully automatic approach for liver classification without contrast agents.
  • The method shows competitive performance against state-of-the-art techniques.
  • The approach holds potential for clinical application in early liver disease diagnosis.
