Table 4.
Features ranked by mean relevance score for the features for test lesions in each class. Percentages do not sum to 100% because some lesions only have a subset of the features listed above

Focal nodular hyperplasia | Isointense on venous/delayed phase (79.4%) | Arterial phase hyperenhancement (65.8%) | Central scar (37.4%) | N/A |
