It was likely there 3 weeks ago but not picked up on. The CT slice thickness may have been too large to detect it very well. What I mean by this is different facilities/radiologists/protocols use different slice thickness on CT scans. A 1mm thickness is very precise but take longer with more radiation exposure when compared to a 2mm, 3mm, 5mm or 10mm. There are other reasons also for the different thickness use. Often times CT will have 5mm between each slice and a small met can squeeze in between those slices without being easily noticed. Small mets are not that easy to see especially in some livers especially without contrast. A radiologist might could go back now in hindsight and see it now. But when you add the PET, it is very easy to see even a small met because of the way the uptake lights up. Now it may have been smaller three weeks ago making it even harder to see. Hope this helps
