I am in the US and FDG PET does not work for NET. The "older" scan was Pet radiolabeled with indium-111. Comparison is here: http://prntscr.com/o02jsg Left is the newer scan, which uses Gallium 68. The primary tumor is uppermost right side, liver metastasis is left side, and small lower lighted up areas are lymph nodes. All will be removed soon. Lit up area below is the radiotracer in my bladder before urinating. :-)

Strange to see images from my specialty here on HN, but no. On the right hand side you have a classic planar OctreoScan (and from posterior view at that). What you have on the left side is a 68Ga-DOTA-(TOC/NOC/TATE) scan, not the new 68Ga-FAPI scan which I believe is only available in Heidelberg, Germany for now. While 68Ga-DOTA-(TOC/NOC/TATE) are probably not as good as 68Ga-FAPI (we don't know that yet, pending research) it is markedly better than OctreoScan, especially for small primary lesions, as is often the case in NETs.

Wow! Do you have DICOM files for that! Good thing they found all that! Good luck with all the surgery, you'll get better soon!

Yes I have all the Dicom files and put all the images on a password protected server so I can share with prospective surgeons. This really helped me find the best possible surgeon. THANKS!

Good luck with the surgery! You probably got Octreoscan which is used for NET - it's SPECT imaging which is generally worse that PET, but (until now) there wasn't a good PET tracer that works in NET. Awesome to hear a story of how this new tracer could really help patients.

Sorry, this is not true. 68Ga-labelled DOTATOC, DOTANOC, and DOTATATE are used diagnosis and therapy of NETs for more than 10 years. They are widely available in Europe and in some major US centers. If the new 68Ga-FAPI will be better remains to be seen, I suppose the Heidelberg group will publish some research soon.

Yes it was an Octreotide scan.
