Differentiation of pancreatic adenocarcinoma and chronic pancreatitis…

- - - - Death rate
      - Difficulty in diagnosis
    - - Different but can be confused with PDAC
        
        Overlap in histomorphological features
        
        Difficulties of accurate tissue sampling
      - Related to PDAC
        
        Precusor
        
        PDAC can induce CP in sounding tissue
      - Ensure accurate diagnosis
        
        Mention ultrasound endoscopy
        
        Histopathology is the only accurate way for differential diagnosis of PDAC and CP
  - - - Premise of weak labels / coarse labels
      - MIL is essential, but oversimplified with some shortcomings
        
        Multiscale features: example of PDAC/CP diagnosis critieria
        
        Spurious correlations: picking up background,
        
        Region-based annotation regquired
      - Graph models and vision transformer
        
        Spatial relations
        
        Capture features that span scales and tiles
  - - - The finding of collagen features are consistent with previous findings
- - - - BF from ImageNet
      - SHG from CurveAlign
