This study shows that quantitative analysis of tongue images can help diagnose appendicitis and pancreatitis. Analyzing tongue color and texture features aids in medical diagnosis.

Area of Science:

  • Medical Diagnostics
  • Biomedical Imaging
  • Computational Pathology

Background:

  • Traditional tongue inspection is a subjective diagnostic method.
  • Objective, quantitative analysis of tongue features is needed for improved diagnostic accuracy.
  • Disease states can manifest observable changes in tongue appearance.

Purpose of the Study:

  • To investigate the relationship between specific diseases and quantitative features of the human tongue.
  • To develop a method for objective disease classification using digital tongue images.
  • To validate the utility of quantitative tongue feature analysis in medical diagnosis.

Main Methods:

  • Acquisition of digital tongue images from three subject groups: healthy, appendicitis, and pancreatitis.

Related Experiment Videos

  • Extraction of chromatic and textural measurements from tongue images.
  • Application of feature selection to identify key diagnostic indicators.

    • Main Results:

    • Distinct quantitative differences in tongue color and texture were observed between healthy individuals and those with appendicitis or pancreatitis.
    • Feature selection successfully identified measurements that effectively differentiate between the three groups.
    • The quantitative classification approach demonstrated potential for accurate diagnostic categorization.

    Conclusions:

    • Quantitative analysis of tongue images provides objective data for medical diagnosis.
    • This method shows promise for non-invasive diagnostic tools for conditions like appendicitis and pancreatitis.
    • Tongue inspection, when quantified, can be a valuable component of clinical assessment.
