Title:Deep Texture Analysis: An answer to why CNN goes with experts’ scores, not the pathological reports

Abstract: Artificial intelligence (AI) research for medical diagnosis started soon after human began to use computer, initially called artificial neural network (ANN) and now convolutional neural network (CNN).  ANN has been mainly explored to classify the experts’ handcrafted features from the raw images, while CNN adds a component to extract the features from the raw images.

Experimental evidences have shown that CNN can be trained by a large number of the raw images with experts’ scores (or labels) to march or even surpass the experts’ performance for both non-medical and medical diagnosis applications.  However, the performances of both the CNN models and the experts on medical diagnosis dropped dramatically when the labels of the raw images were replaced by the medical pathological reports.

Accumulated medical knowledge reveals that the lesion heterogeneity is a footprint of lesion evolution and ecology, and the heterogeneity is also an indicator of lesion progress and response to intervention.  The heterogeneity can be reflected by the image contrast distribution (or texture patterns) across the lesion volume.  Image textures have been shown as an effective descriptor of the lesion heterogeneity for computer-aided diagnosis.

Can we go into the raw images to map the image contrast distribution into texture images and train CNN to learn from the texture images?  This question is the central theme of this presentation with application to CT colonography or virtual colonoscopy, i.e. from AlphaGo (围棋) to AlphaPolyp (肠癌).
