¹¹C-acetate, staging hepatocellular carcinoma (HCC), comparison with ¹⁸F-FDG. Clinical history: 69 y.o. patients with HCC at presentation. Staging of a poorly differentiated HCC, patient underwent acetate and FDG study in a single day examination. PET/CT findings: acetate (a MIP and fused images): no areas of significant tracer uptake in the liver. The hypodense lesion in the IV segment (CT images red arrow) is consistent with the primary HCC. FDG (b MIP and fused images): increased tracer uptake in the IV segment (CT images red arrow) is consistent with the primary HCC
