The prognosis of liver disease depends on the extent of fibrosis, which is usually staged with the use of liver biopsy. The limitations of biopsy have led to the development of noninvasive tests, which the authors review. Learn more: nej.md/4hwZMgj #MedSky #GastroSky

HOTSPoT paves the way for scalable, explainable, and accessible AI in liver pathology. Open science, clinical relevance, and technical excellence — all in one model. Congrats to the entire team! #DigitalPathology #OpenSource #AIinMedicine

Behind this innovation is a multidisciplinary, international team — but a special shoutout to Giorgio Cazzaniga, who led dataset creation, annotation, model design & implementation. A stellar example of clinician-engineering leadership. 🙌

Clinical validation? Yes. In 35 liver biopsies, HOTSPoT's automated tract count matched human observers (κ = 0.90) and correlated strongly with fibrosis stage (r = 0.87). A true step forward in reproducible pathology. 📈🩺

HOTSPoT isn't just a model — it's a tool. It's released in TorchScript format, integrates with QuPath, and includes a custom WSInfer pipeline for WSI-level inference. ⚙️ Code & model 👉 github.com/Gizmopath/HO...

Trained on 223 cases and tested across 5 international centers, HOTSPoT achieved Dice scores up to 0.92, showing minimal domain shift. That means: robust performance across scanners, stains, and disease contexts. 🌍📊

Liver histology is essential in diagnosing autoimmune and inflammatory diseases — but manual annotation is time-consuming and variable. HOTSPoT tackles this with automated, high-performance segmentation of portal tracts in H&E-stained slides. 🧠🧫

🔥 HOTSPoT sets a new benchmark in liver pathology: open-source, accurate, and externally validated tool for portal tract segmentation. A brilliant team effort led by Giorgio Cazzaniga — whose vision and drive made it possible 👏 rdcu.be/ew7qh #AI #Digitalpathology

Great visit to EKFZ Digital Health Institute! Gave a talk at Jakob Kather’s lab, had great 1:1s with team members, and visited our PhD student Elisa Merelli, who's spending part of her PhD here💡🔬 #DigitalHealth #AI #Research @jnkt.bsky.social @janclusmann.bsky.social
