UMAP of the normalized histogram representation of WSI neutrophil density for the entire dataset. All patches in this figure depict the 256 × 256 pixel CLAM patch with the maximum neutrophil density from the corresponding WSI. The UMAP displayed with patches depicts more clearly visible crypts and tissue edges in the normal cluster max patches than the active disease cluster (A). The UMAP displayed with circle markers highlights the separability of the two classes (B). Example patches are shown with their predicted neutrophil segmentation in green (C, D, E, F). Looking deep into the normal cluster, expected patches (C) and active disease outliers (D) show tissue edges and few segmented neutrophils. In the active disease cluster, expected patches (E) and normal tissue CD outliers (F) both show a larger number of segmented neutrophils, with fewer tissue edges visible (F).

Each image volume from the mixed CT dataset is windowed for blood (width 130 Hounsfield units, level 50 Hounsfield
units), converted into a 2D montage from resampled axial slices and normalized. A multitask deep learning model then
simultaneously performs two classifications: CT vs CTA and artifact vs no artifact.

A comparison of the number of learnable parameters and the types and number of skip connections in our five models. Note that the skip connections type column lists operations which show how residual information is reintegrated when the skip / residual connection or parallel processing branch rejoins the network.
