It has been reported that the positive detection rate of Fluorine-18-fluorodeoxyglucose ((18)F-FDG) metabolism in positron emission tomography (PET) imaging, for the diagnosis of hepatocellular carcinoma (HCC) is only about 50%. In particular, (18)F-FDG PET imaging is prone to false negative findings in HCC. Transforming growth factor-beta1 (TGF-β1) shows over expression rates in early HCC liver tissue growth and promotes tumor invasion and metastases. Our aim was to use In this study, we used the feasibility of iodine-125 ((125)I)-labeled TGF-β1 antibody as a nuclear medicine imaging target in HCC...

A technique for generating MRI-derived synthetic CT volumes (MRCTs) is demonstrated in support of adaptive liver stereotactic body radiation therapy (SBRT). Under IRB approval, 16 subjects with hepatocellular carcinoma were scanned using a single MR pulse sequence (T1 Dixon). Air-containing voxels were identified by intensity thresholding on T1-weighted, water and fat images. The envelope of the anterior vertebral bodies was segmented from the fat image and fuzzy-C-means (FCM) was used to classify each non-air voxel as mid-density, lower-density, bone, or marrow in the abdomen, with only bone and marrow classified within the vertebral body envelope...

Computed tomography-guided radiofrequency ablation (CT-RFA) and laparoscopic RFA (L-RFA) have been used to treat intrahepatic recurrent small hepatocellular carcinoma (HCC) against the diaphragmatic dome. However, the therapeutic safety, efficacy, and hospital fee have never been compared between the two techniques due to scarcity of cases. In this retrospective study, 116 patients were divided into two groups with a total of 151 local recurrent HCC lesions abutting the diaphragm. We compared overall survival (OS), local tumor progression (LTP), postoperative complications, and hospital stay and fee between the two groups...

Treatment options for hepatocellular carcinoma have evolved over recent years. Interventional radiologists and surgeons can offer curative treatments for early stage tumours, and locoregional therapies can be provided resulting in longer survival times. Early diagnosis with screening ultrasound is the key. CT and MRI are used to characterize lesions and determine the extent of tumour burden. Imaging techniques are discussed in this article as the correct imaging protocols are essential to optimise successful detection and characterisation...

INTRODUCTION: Combined hepatocellular-cholangiocarcinoma (CHC or cHCC-CC) is a rare primary liver tumor displaying histological features of both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA). Most patients are not suitable for surgery because of the advanced stage of the disease at the moment of diagnosis. We decided to review the literature in order to identify the outcomes after liver transplantation for CHC and to clarify which is the most appropriate treatment. MATERIAL AND METHODS: A systematic literature search was performed...

Non-alcoholic fatty liver disease (NAFLD) is an ailment affecting and increasing a number of people worldwide diagnosed via non-invasive imaging techniques, at a time when a minimum harm caused by medical procedures is rightfully emphasized, more sought after, than ever before. Liver steatosis should not be taken lightly even if its evolution is largely benign as it has the potential to develop into non-alcoholic steatohepatitis (NASH) or even more concerning, hepatic cirrhosis, and hepatocellular carcinoma (HCC)...
