In clinical imaging modalities, MRI is suitable for preoperative examination. And fluorescence imaging has been proposed to improve the detectability of cancer lesions during the operation. However, the specificity and accuracy of the two imaging modalities is limited. To improve the prognosis and survival rate of the patient suffering from hepatocellular carcinoma (HCC), it is very important to develop a specific probe to achieve early detection and precise resection of HCC. We selected HCC targeting peptide SP94 to conjugate with a NIR dye and Gd chelated DOTA to enhance the specificity of different imaging modalities...

BACKGROUND: After orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC), recurrent HCC mostly develops within 2 years. All cases of de novo HCC described so far occurred later than 2 years after OLT. Prevention of post-transplantation HCC has usually been tried to achieve by curing or controlling recurrent liver disease. This has been rationale for treatment with interferon (IFN)/ribavirin of HCV-recurrence in patients after OLT, transplanted for advanced HCV-induced liver disease and/or HCC...

We have synthesized a graphene oxide (GO)-based theranostic nanodelivery system (GOTS) for magnetic resonance imaging (MRI) using naturally occurring protocatechuic acid (PA) as an anticancer agent and gadolinium (III) nitrate hexahydrate (Gd) as the starting material for a contrast agent,. Gold nanoparticles (AuNPs) were subsequently used as second diagnostic agent. The GO nanosheets were first prepared from graphite via the improved Hummer's protocol. The conjugation of the GO and the PA was done via hydrogen bonding and π-π stacking interactions, followed by surface adsorption of the AuNPs through electrostatic interactions...

The incidence of hepatocellular carcinoma (HCC) in patients with thalassemia is increasing, the two well recognized HCC risk factors in thalassemia being iron overload and chronic hepatitis C. The carcinogenicity of iron is related to its induction of oxidative damage, whereas chronic hepatitis leads to necroinflammation that can accelerate progression to HCC. We hereby report the case of a non transfused, hepatitis C-negative, β-thalassemia intermedia (β-TI) patient from our practice who had evidence of significant iron overload, suggesting the importance of increased iron burden as a HCC risk factor in this patient population...

BACKGROUND: Fibrolamellar hepatocellular carcinoma (FLC) is a rare malignancy occurring in young patients without cirrhosis. Objectives of our study were to analyze contrast material uptake in hepatobiliary phase imaging (HBP) in gadoxetic acid-enhanced liver MRI in patients with FLC and to characterize imaging features in sequence techniques other than HBP. METHODS: In this retrospective study on histology-proven FLC, contrast material uptake in HBP was quantitatively assessed by calculating the corrected FLC enhancement index (CEI) using mean signal intensities of FLC and lumbar muscle on pre-contrast imaging and HBP, respectively...

BACKGROUND: Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a rare primary liver tumor, which has overlapping imaging features with mass forming intra-hepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC). Previous studies reported imaging features more closely resemble ICC and the aim of our study was to examine the differential MRI features of cHCC-CC and ICC with emphasis on enhancement pattern observations of gadolinium enhanced MRI. METHODS: Institutional review board approval with consent waiver was obtained for this retrospective bi-centric study...

BACKGROUND: Carcinosarcoma of the liver is a very rare tumor composed of a mixture of carcinomatous and sarcomatous elements. Less than 25 adequately documented cases have been reported, with inadequate description of imaging features. In order to improve the awareness of this rare tumor, this study aimed to analyze the clinicopathologic and imaging features of six cases of hepatic carcinosarcoma (HCS) confirmed by surgical pathologic evaluation. METHODS: We retrospectively studied the clinicopathologic and imaging features of six cases of HCS (matching the World Health Organization definition) and discussed the differential diagnosis on the basis of imaging findings...

BACKGROUND: Hepatitis B virus (HBV) infection is common with major clinical consequences. In Asian Americans, the HBsAg carrier rate ranges from 2% to 16% which approximates the rates from their countries of origin. Similarly, HBV is the most important cause of cirrhosis, hepatocellular carcinoma (HCC) and liver related deaths in HBsAg positive Asians worldwide. AIM: To generate recommendations for the management of Asian Americans infected with HBV. METHODS: These guidelines are based on relevant data derived from medical reports on HBV from Asian countries as well as from studies in the HBsAg positive Asian Americans...

OBJECTIVE: Many improvements have been made in diagnosing hepatocellular carcinoma (HCC), but the radiological hallmarks of HCC have remained the same for many years. We prospectively evaluated the imaging criteria of HCC, early HCC and high-grade dysplastic nodules (HGDNs) in patients under surveillance for chronic liver disease, using gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) MRI and diffusion-weighted imaging. DESIGN: Our study population included 420 nodules >1 cm in 228 patients...

BACKGROUND AND AIMS: Hepatobiliary MRI provides additional information beyond size and number of the tumor, and may have prognostic implication. We tested whether pre-transplant radiologic features on MRI can stratify risk of tumor recurrence after liver transplantation (LT) for hepatocellular carcinoma (HCC). METHODS: A total of 100 liver transplanted patients who had preoperative gadoxetic acid-enhanced MRI, including the hepatobiliary phase (HBP), were reviewed for size, number, morphologic type (e...

A 0.5%-iron-containing fiducial marker, Gold AnchorTM (Naslund Medical AB, Huddinge, Sweden), has been recently developed. Herein, we report our initial experiences with the clinical use of the Gold AnchorTM (GA) in radiotherapy for liver tumors. Data of four consecutive patients with liver tumors, including two liver metastases and two hepatocellular carcinomas, were retrospectively analyzed. The GA was percutaneously placed under local anesthesia, close to the tumor. Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (MRI) was performed after the placement of the GA...

RATIONALE: Hemangioma of the liver is a benign hepatic tumor, more common in women than in men, which is typically asymptomatic, solitary, and incidentally discovered. Atypical hemangioma is a variant of hepatic hemangioma with atypical imaging finding features on CT and MRI that can be confused with hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and mixed hepatocellular cholangiocarcinoma (HCC-CC). PATIENT CONCERNS: We report a case of atypical hepatic hemangioma mimicking HCC-CC: A 59-year-old man was referred to our hospital for a hepatic lesion that was 4...
