The Liver Imaging Reporting and Data System (LI-RADS) uses an algorithm to assign categories that reflect the probability of hepatocellular carcinoma (HCC), non-HCC malignancy, or benignity. Unlike other imaging algorithms, LI-RADS utilizes ancillary features (AFs) to refine the final category. AFs in LI-RADS v2017 are divided into those favoring malignancy in general, those favoring HCC specifically, and those favoring benignity. Additionally, LI-RADS v2017 provides new rules regarding application of AFs. The purpose of this review is to discuss ancillary features included in LI-RADS v2017, the rationale for their use, potential pitfalls encountered in their interpretation, and tips on their application...

BACKGROUND/AIM: Selective intraarterial radionuclide therapy (SIRT) with yttrium-90 (Y-90) resin microspheres presently has successful results in primary or metastatic inoperable liver tumors. This procedure, which is also known as radioembolisation, delivers high doses of radiation selectively to hepatic tumors while minimum healthy liver exposure. The aim of this study was to present our clinical experience of radiomicrosphere therapy for the treatment of patients with unresectable hepatocellular carcinoma (HCC)...

Since sorafenib was introduced in 2007 for treating advanced hepatocellular carcinoma (HCC), 15 patients have achieved a complete response (CR) in advanced HCC. However, only four of these reports can be regarded as real CRs involving adequate assessments including imaging, serum tumor markers, and histologic examinations of completely resected specimens. A 54-year-old man with hepatitis C virus (HCV)-related liver cirrhosis (LC) presented to our unit. A CT scan demonstrated a 3.8-cm arterial hypervascular/portal-washout mass in the right lobe and invasion in the right portal vein...

PURPOSE: To prospectively monitor changes in tumor perfusion of hepatocellular carcinoma (HCC) in response to doxorubicin-eluted bead based transarterial chemoembolization (DEB-TACE) using perfusion-CT (P-CT). METHODS AND MATERIALS: 24 patients (54-79 years) undergoing P-CT before and shortly after DEB-TACE of HCC were prospectively included in this dual-center study. Two readers determined arterial-liver-perfusion (ALP, mL/min/100mL), portal-venous-perfusion (PLP, mL/min/100mL) and the hepatic-perfusion-index (HPI, %) by placing matched regions-of-interests within each HCC before and after DEB-TACE...

BACKGROUND: Rapid advances in liver imaging have improved the evaluation of hepatocarcinogenesis and early diagnosis and treatment of hepatocellular carcinoma (HCC). In this situation, detection of early-stage HCC in its development is important for the improvement of patient survival and optimal treatment strategies. Because early HCCs are considered precursors of progressed HCC, precise differentiation between a dysplastic nodule (DN), especially a high-grade DN, and early HCC is important...

Hepatic fibrosis is potentially reversible; however early diagnosis is necessary for treatment in order to halt progression to cirrhosis and development of complications including portal hypertension and hepatocellular carcinoma. Morphologic signs of cirrhosis on ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) alone are unreliable and are seen with more advanced disease. Newer imaging techniques to diagnose liver fibrosis are reliable and accurate, and include magnetic resonance elastography and US elastography (one-dimensional transient elastography and point shear wave elastography or acoustic radiation force impulse imaging)...

Patients with hepatocellular carcinoma (HCC) may be eligible for liver transplantation. Liver transplant candidates with HCC compete for the same deceased donor organs as those without HCC. These scarce organs must be allocated fairly and justly to those who will benefit most. Unlike most other cancers, HCC is often diagnosed noninvasively by imaging without biopsy confirmation. Therefore, radiologists play an important role in diagnosing definite HCC (i.e., LR-5 category) that counts toward staging and determination of liver transplant eligibility...

Surveillance by ultrasonography for hepatocellular carcinoma (HCC) for individuals with cirrhosis is recommended. There is debate regarding the effectiveness of surveillance in reducing mortality and there is little information on the harms available to patients considering surveillance. The aim of this study was to provide estimates of both the benefit and harms of surveillance. A Markov model was built to simulate outcomes of individuals entering surveillance. Following identification of a focal lesion by ultrasound surveillance further investigations were defined by the EASL-EORTC recall policy...

BACKGROUND: The Milan criteria are widely accepted among many centers. However, patients with hepatocellular carcinoma beyond the Milan criteria might still benefit from liver transplantation (LT) when tumor itself is not aggressive. [(18)F] fluorodeoxyglucose positron emission tomography/computed tomography imaging could provide useful information of tumor behaviors, which is helpful to predict the prognosis for many tumors. METHOD: In order to determine its role in candidate selection for LT, we therefore retrospectively analyzed 103 recipients with preoperative positron emission tomography (PET) findings...

Purpose: The prognosis of patients with hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE) is often uncertain. We aimed to utilize analytic morphomics, a high-throughput imaging analysis, to assess if body composition is predictive of post-TACE survival. Materials and Methods: We included patients from a single center (Ann Arbor VA) who had TACE as the primary treatment for HCC and had a pre-treatment CT scans. Univariate analysis and multivariate conditional inference tree analysis were utilized to identify the morphomic characteristics predictive of one-year survival...
