  1. Lesions were classified either visually or based on the absolute peak tracer uptake. In this case, a change of more than 30 % in peak tracer uptake was rated as a significant increase (=progressive) or decrease (=regressive). All other lesions were classified stable. The listed number of discrepant lesions refers to the comparison of each visual analysis to the quantitative assessment
