Fig. 6: The visual outcomes of the PJI intelligent pathological diagnosis model.
From: Clinically applicable optimized periprosthetic joint infection diagnosis via AI based pathology
From left to right, the images represent a whole image slide, a visualization heatmap of the PJI supervised learning model, and a visualization heatmap of the PJI weakly supervised learning model. The color gradient from light to dark indicates diagnostic weight from low to high. a The tissue shows not only an aggregation of neutrophils but also a loss of its original structure, becoming more porous. b Differences in the cytoplasm and nuclear morphology of neutrophils are observed, depending on their proximity to blood vessels (indicated by the direction of the red arrow).
