From: A dual-tracer approach using [11C]CH and [18F]FDG in HCC clinical decision making
PET/CT imaging of a 49-year-old male patient (#1) known with hemochromatosis-related cirrhosis and multifocal HCC. Underwent MWA of solitary HCC node (32 mm) in segment VIII to ensure eligibility for orthotopic liver transplantation (OLT). Post-therapy MRI follow-up at three months displayed further progression of several intrahepatic lesions and potential tumour thrombus in v. porta, which prompted dual-tracer diagnostic with [18F]FDG and [11C]CH PET/CT. Both tracers found a metastasis in the m. adductor longus muscle (A for [11C]CH, and C for [18F]FDG, arrow), while an ablation site recurrence was only found by [18F]FDG (D) and not by [11C]CH (B). In addition, MIP images show several mediastinal lymph nodes only found by [18F]FDG (F), whereas [11C]CH (E) has physiological uptake in the same region. Due to lymphatic and extrahepatic disease patient received palliative chemotherapy
