My ex-husband had a scan to check for distant mets. His PET went from his head to his knees...why there? dunno. It's a good stopping point past where the organs reside, I suppose.

The PET showed bilateral lymph node involvement...nothing anywhere else. The RO interpreted the PET results as indicating metastatic cancer. What happened was the PET lit up nodes involved in an infection from which my ex-husband had just recovered. He had an MRI recently and nothing showed up in his nodes. They were never excised and he didn't receive treatment.
