A member asked:

Can a bone lesion that was apparently inactive on pet/ct become active later? it's a lytic lesion of the clavicle with very thin sclerotic rim.

Yes: An inactive lesion on a pet/ct scan can become active if there has occurred a stress reaction/fracture or pathological fracture through the tihnned bone. Also benign cystic lesions can also become malignant and then become active.
