Table 3 Study form for reviewers’ results (per lesion)

1

Normal

Confident that no tumor recurrence is present in the ablation zone

2

Probably benign

The appearance of the ablated lesion is compatible with post-ablational inflammation or rim-like characteristics

3

Equivocal

There is doubt whether the imaging features indicate local tumor progression or inflammation

4

Probably malignant

Confident about local progression in the ablation zone

5

Impaired quality

Quality of the images precludes adequate diagnosis
