Table 3 A summary of cases with disagreement in response categories for qualitative and PERCIST evaluation with a possible clinical consequence

From: Inter-observer agreement improves with PERCIST 1.0 as opposed to qualitative evaluation in non-small cell lung cancer patients evaluated with F-18-FDG PET/CT early in the course of chemo-radiotherapy

  1. Obs. is number of observers disagreeing with consensus (Cons.)
  2. Cases with more than one observer disagreeing are considered most important
