New lymph node lesions

Nodes that have a short axis < 10 mm are considered non-pathological and should not be recorded, they are considered pathological only if they are larger than 15mm. Therefore, if the node is bigger than 15 mm, it is a new lesion and PD.

Nodes that have a short axis≥ 10 to <15 mm are considered non-targeted lesions and should be followed. So if in a subsequent assessment, the node is bigger than 15 mm, it is a non-target lesion PD.
