HCC survival has improved due to better primary tumor control and development of newer treatment modalities, with imaging techniques playing a crucial role in diagnosis and therapy assessment. Molecular imaging tools such as radiolabeled deoxyglucose and fluorocholine have shown promising value as complementary tools to conventional imaging, guiding treatment planning for patients.
The most prevalent primary malignancy of the liver is hepatocellular carcinoma (HCC); its poor prognosis is mainly related to intrahepatic recurrence and extrahepatic metastases. However, survival from HCC has improved due to better control of the primary tumor, the development of newer treatment modalities, including liver transplant, together with advances in imaging techniques. Therefore, the significance of patient management as corresponds with distant metastases has increased; since the proper evaluation and detection of extrahepatic metastases is crucial to optimize potential therapy for patients. Conventional imaging like CT, MRI play crucial rule in patient's diagnosis and qualifying for a certain type of therapy. More recently, a molecular imaging tool with radiolabeled deoxyglucose and fluorocholine has proved its promising value as a complementary tool to conventional studies. In this review, the frequent sites of metastases and HCC spread are discussed as well as the imaging findings as seen by both conventional imaging techniques and by molecular imaging tools, namely F-18-Choline PET/CT, and FDG PET. The implications of guiding treatment planning have also been discussed.
