Fig. 3From: Computer-assisted tumor grading, validation of PD-L1 scoring, and quantification of CD8-positive immune cell density in urothelial carcinoma, a visual guide for pathologists using QuPathNuclear to cell area ratio measurement heatmap. Panel A shows the HE section of n invasive papillary high-grade urothelial carcinoma (core #34), with the heatmap colored in each cellular detection (C). Towards purple means a lower N:C ration and to yellow a higher one. B and D are zoomed in areas of correspondent A and B images (blue squares). The heatmap views can be set for any of the output measurements. Panel E shows the histogram for all cells in the measurements by normalized values in the softwareBack to article page
