BACKGROUND AND AIMS: With the advent of computer vision algorithms, we hypothesize that histopathology images from endoscopic biopsies may be utilized for automated classification of histologic phenotypes, thus guiding Crohn's disease and ulcerative colitis diagnosis and treatment. The aim of our study is to assess whether artificial intelligence can be used to improve pediatric inflammatory bowel disease outcomes by aiding pathologists with accurate detection of abnormal tissue sections.
METHODS: Three two-dimensional (2D) convolutional neural networks with multiple instance learning were developed to classify histopathology tissue sections as normal vs abnormal and as containing active inflammation and/or chronic changes/architectural distortion.
RESULTS: The abnormal vs normal classification model achieved an accuracy of 0.84, an area under the receiver operating characteristic curve (AUC-ROC) of 0.91, and an F1-score of 0.79. Precision, sensitivity, and specificity were 0.85, 0.74, and 0.91, respectively. The accuracy for predicting active inflammation was 0.85, AUC-ROC was 0.92, and F1-score was 0.78. The accuracy for predicting chronic changes/architectural distortion was 0.86, with an AUC-ROC of 0.93 and an F1-score of 0.76. All 3 models achieved a Matthews correlation coefficient of 0.67.
CONCLUSION: The findings resulting from this study are significant primarily because they indicate that there is a strong artificial intelligence-interpretable signal present in endoscopic whole slide imaging, even with the necessary, weakly supervised method of multiple instance learning.
