Table 2.
Categorized courses of all tracked lesion developments (see section 2.1). Based on AFIL algorithm results all four time points were checked with regard to their global label consistency. Performance verification results of expert visual inspection of relabelled lesion masks are provided (right/false).

Result of the segmentation of initially confluent conglomerates and subsequently consolidating multiple lesion centres.
b
Rare lesion course complicating lesion assignment.
