ON THE COVER
18F-FDG PET/CT has been found useful in evaluating hepatocellular carcinoma metastases, although its role in the diagnosis of primary hepatocellular carcinoma is more limited. Dual-tracer PET/CT with 18F-FDG and 11C-acetate has shown an incremental value and a complementary advantage over single-tracer imaging in the evaluation of hepatocellular carcinoma metastases. Some intrathoracic nodes showing increased 18F-FDG activity could be noncalcified granulomatous nodes and, thus, false-positive for metastasis. This possibility can be minimized by correlating serial PET/CT with other ancillary findings.
