Hi @hopeful33250, I had this done as an outpatient procedure. It took two sessions. The first, the right lobe, was more painful but ok after a day or so. The second, the left lobe, was only slightly uncomfortable the first night. Apparently, the right lobe is much bigger so that makes sense. It translates to abdominal pain right below the rib cage. The liver itself doesn't hurt hardly at all. I hope this helps. I'll do a scan in a couple of months to see black (dead) tumors and see if we have killed them all. I can go back in on the ones that are missed. But I'll see after Lutethera treatment, as I still have to conquor the bones mets once the livers mets are gone. I hope this helps!
