Hello, this is Dr K.. Answers are not medical advice and do not constitute a doctor/patient relationship. I look forward to helping you today.
Fluoro Deoxyglucose is a dye injected during a PET scan
If the lesion has no uptake it means there is a low risk of malignancy
The liver,as a whole, has a low uptake of fdg. It sounds like you have a benign lesion, which are common, and you dont have to worry.
Take a photo and post it or copy and paste
Theres a new lesion that has no fdg uptake It may be an early metastasis or may be benign. There is most likely a single liver metastasis. A coregistered ct lesion just means its not seen on Ct scan.
Its unlikely that a metastasis has no uptake. The Dr is also considering the clinical picture. This may be a met that is early and shows no uptake or it may be benign. Theres no way to know. The uptake pattern in the chest lymph nodes is less clear. the Dr is stating it could be a met or it could be an inflammatory reaction. Theres often no way to get a 100 percent answer. All they can give is a best clinical opinion. I am sorry
No not necessarily. As the radiologist stated, it is suspicious for an early met. There must be something he or she is seeing to make it look suspicious for metastasis.
