A representative case of regional LN metastasis predicted by optimal SUVmax cut-off values, but not by the fixed SUVmax cut-off value of 2.5. (a) A mildly hypermetabolic lymph node (arrow) was observed in the left perirectal region. The long-axis diameter of the LN was 6 mm, and the patient was classified into the small LN group according to the size criteria. (b) The SUVmax of the LN was 1.8, and exceeded the optimal SUVmax cut-off value of 1.1. Histopathologic examination revealed that the lesion was a metastatic LN
