Automated segmentation of rheumatoid arthritis immunohistochemistry stained synovial tissue

Published in 27th Conference on Medical Image Understanding and Analysis, 2023

We train a UNET on a hand-curated, heterogeneous real-world multi-centre clinical dataset R4RA, which contains multiple types of IHC staining. The model obtains a DICE score of 0.865 and successfully segments different types of IHC staining, as well as dealing with variance in colours, intensity and common WSIs artefacts from the different clinical centres.

MUSTANG: Multi-Stain Self-Attention Graph Multiple Instance Learning Pipeline for Histopathology Whole Slide Images

Published in British Machine Vision Conference, 2023

Here we propose an end-to-end multi-stain self-attention graph (MUSTANG) multiple instance learning pipeline, which is designed to solve a weakly-supervised gigapixel multi-image classification task, where the label is assigned at the patient-level, but no slide-level labels or region annotations are available. The pipeline uses a self-attention based approach by restricting the operations to a highly sparse k-Nearest Neighbour Graph of embedded WSI patches based on the Euclidean distance.

Going Beyond H&E and Oncology: How Do Histopathology Foundation Models Perform for Multi-stain IHC and Immunology?

Published in Workshop on Advancements In Medical Foundation Models @ NeurIPS24, 2024

Do histopathology Foundation Models trained on H&E cancer datasets enhance performance for Immunohistochemistry autoimmune datasets? Do they produce more relevant Whole Slide Image heatmaps, aligned with autoimmune aetiology? We empirically examine these questions in this paper.
