PET Image Noise Reduction, Ladefoged, C., Hasbak, P., Hornnes, C.,…

- - - - Can be analyzed through preserved glucose metabolism
  - - - lack measures on clinical accuracy
        
        Relies on large number of patient data
- - - - CT Scan
      - FDG-PET
  - - - Gaussian filtering
  - - - Static PET image
      - Gated PET images
    - - Standardized Uptake Value Normalization
      - Scaling of intensities between 0 and 1
    - - Resampled to match PET images
- - - - replaced strided with transposed convolution
      - Added concatenation
      - Similar to encoding
    - - batch normalization
      - ReLU
      - Convolutions
      - dropout
      - strided convolution
      - batch normalization
      - ReLU
  - - - Used a software for imaging solutions
  - - - peak signal to noise ratio
      - normalized root mean squared error
- - - - De-noised images are more correlated
        
        ESV R = 98%
        
        LVEF = 83%
        
        EDV R = 98%
      - Low variance error for de-noised
  - - - 1% (mean, max. std)
