Since I don't see any mention of a ND, I was wondering how they determined there was no cancer in the lymph nodes. Was that just based on a CT, or MRI?

My CC extensively uses PET/CT scans - all of mine have been full body. I had one prior to my ND surgery and I have had them for all my post TX follow-up scans.

Their logic is they have very good PET/CT scanners so, at least in my case, they prefer to have the PET results along with the CT results.

Currently my CC does not have a PET/MRI scanner. Also, they do not use PET/CT result for planning. They have dedicated CT planning scanners for that.

In my opinion, the PET results might help with the DX and any good CCC will consider it along side other tests and scans (CT, MRI, Ultrasound, biopsy, etc.).
