Post-study: Measurable effect of harmonisation

Kappa values infiltrating primary

1. LN station infiltrated by primary

0,70

→ report positively

0,60

0,50

2. Anatomical allocation

0,40

→ use atlas!

3. Bulky disease

0,10

→ report all affected LN stations

1. Viewing technique

Kappa values bulk/no bulk

0,80

→ PET-MIP (LK?) -> PET volume -> CT

0,70

2. Reading criteria

0,50

→ visibility in the MIP leading
