BACKGROUND AND AIMS: The diagnosis of non-alcoholic steatohepatitis (NASH) and fibrosis staging are central to non-alcoholic fatty liver disease (NAFLD) assessment. We evaluated multi-parametric magnetic resonance (MR) in the assessment of NASH and fibrosis using histology as standard in NAFLD. METHODS: Seventy one patients with suspected NAFLD were recruited within one month of liver biopsy. MR data were used to define the liver inflammation and fibrosis score (LIF 0-4)...

BACKGROUND/AIMS: Portal hypertension (PH) is a common complication of chronic liver disease and results in esophageal and gastric variceal bleeding, which is associated with a high mortality rate. Measurement of the hepatic venous pressure gradient (HVPG) is considered the gold standard for diagnosing PH and estimating the risk of varices and bleeding. In contrast, upper gastrointestinal (GI) endoscopy (UGE) can reliably demonstrate the presence of varices and bleeding. Both measures are invasive, and HVPG is mainly restricted to tertiary centers...

OBJECTIVE: We have reported about real-time tissue elastography (RTE), which displays relative strain by measuring the relative distortion of the tissue, and found this information to be useful for diagnosing liver fibrosis. However, its use in predicting hepatocellular carcinoma has not been reported as yet. Here, we investigated RTE to predict liver carcinogenesis in patients with chronic hepatitis C virus (HCV) infection. METHODS: We enrolled 160 patients with chronic HCV, who were followed up for 39...

BACKGROUND: Noninvasive assessment of liver fibrosis has important clinical significance. Different techniques including two-dimensional shear-wave elastography (2D SWE) and real-time tissue elastography (RTE) are reported to be useful for the noninvasive diagnosis of hepatic fibrosis. All these techniques are affected by many factors. How to choose a reasonable method needs further studies. PURPOSE: This study was conducted to comparatively assess the diagnostic performance of 2D SWE and RTE in patients with Chronic Hepatitis B (CHB) and influence of inflammation on the stiffness values obtained by both techniques, so as to objectively assess the reasonable choice between these 2 elastography techniques for noninvasive assessment of hepatic fibrosis in clinical practice...

PURPOSE: Hepatic magnetic resonance elastography (MRE) is currently a breath-hold imaging technique. Patients with chronic liver disease can have comorbidities that limit their ability to breath-hold (BH) for the required acquisition time. Our aim was to evaluate whether stiffness measurements obtained from a navigator-triggered MRE acquisition are comparable to standard expiratory breath-hold, inspiratory breath-hold or free-breathing in healthy participants. MATERIALS AND METHODS: Twelve healthy participants were imaged using the four methods on a clinical 1...

INTRODUCTION: Non-alcoholic steatohepatitis (NASH) is a serious form of non-alcoholic fatty liver disease (NAFLD) that can progress to advanced fibrosis, cirrhosis, and hepatocellular carcinoma. Differentiating between non-alcoholic fatty liver (NAFL) and NASH/advanced fibrosis is an important step in the management of NAFLD. Metabolic syndrome (MS) and its components are important risk factors for NAFLD, and NASH is thought to be the hepatic injury of MS. The prevalence of NASH among NAFLD patients with MS is thought to be high...

In these days of political vagueness, to use a kinder term, although many would describe the situation as turmoil, in Europe, there are success stories to be lauded. Notwithstanding the direction individual countries choose in relation to closer or not so close co-operation in Europe and the direction the political agenda will travel over the next few years, I believe science and in particular medicine has benefited enormously form close co-operation across the European Union and with colleagues outside this political and trading block of nations...

Chronic hepatitis B virus (HBV) infection is a major cause of cirrhosis and hepatocellular carcinoma (HCC). Applying the same strategies for antiviral therapy and HCC surveillance to all chronic hepatitis B (CHB) patients would be a burden worldwide. To properly manage CHB patients, it is necessary to identify and classify the risk for HCC development in such patients. Several HCC risk scores based on risk factors such as cirrhosis, age, male gender, and high viral load have been used, and have negative predictive values of ≥ 95%...

According to the increasing need for accurate staging of hepatic fibrosis, the ultrasound (US) elastography techniques have evolved significantly over the past two decades. Currently, US elastography is increasingly used in clinical practice. Previously published studies have demonstrated the excellent diagnostic performance of US elastography for the detection and staging of liver fibrosis. Although US elastography may seem easy to perform and interpret, there are many technical and clinical factors which can affect the results of US elastography...

BACKGROUND: Patients with primary sclerosing cholangitis (PSC) develop progressive liver fibrosis and end-stage liver disease. Non-invasive and widely available parameters are urgently needed to assess disease stage and the risk of clinical progression. Transient elastography (TE) has been reported to predict fibrosis stage and disease progression. However, these results have not been confirmed in an independent cohort and comparison of TE measurement to other non-invasive means is missing...
