The aim of this study was to determine the performance of shear wave elastography (SWE) with a propagation map in the diagnosis of hepatic fibrosis, and to assess its reliability with transient elastography (TE) as the reference standard. Our prospective study included 115 consecutive patients with suspected or alleged chronic hepatitis. Patients underwent SWE by two different operators and TE by sonographers on the same day. The correlation coefficient of the intra-class correlation test between an experienced radiologist and a third-year radiology resident was 0...

MR elastography is a novel method for non-invasive fibrosis assessment, not yet sufficiently validated. In a recent study in 104 patients Park, Gastroenterology 2017; 152: 598-602), MRE was compared to transient elastography for the diagnosis of fibrosis is nonalcoholic fatty liver disease. The current viewpoint critically appraises this study.

Metabolic syndrome, an etiological factor in non-alcoholic fatty liver disease (NAFLD), is often present in hemodialysis patients. Little is known about the prevalence of, and factors associated with, liver fibrosis in hemodialysis populations. We used transient elastography (TE) to investigate these phenomena. 659 patients treated with chronic hemodialysis were enrolled. We excluded those with excess alcohol intake, liver stiffness measurement (LSM) failure, or unreliable LSM values. LSM ≥8.0 kPa was used as a cutoff suggesting clinically relevant fibrosis...

BACKGROUND: Controlled attenuation parameter (CAP) and liver stiffness (LS) measured by transient elastography (TE, Fibroscan®) have been used for steatosis and fibrosis assessment. We evaluated the effect of meal intake on CAP and LS values. METHODS: Forty patients who had had a liver biopsy within the previous month were recruited. The biopsy was graded for fibrosis (F) and steatosis (S) stagings. TE was performed after overnight fasting (baseline values) and 15, 30, 45, 60, 90, and 120 min following the intake of a standard commercial formula meal, and every 30 min until LS and CAP values returned to baseline...

As of 2016, there is no evidence-based pathway to stratify the risk of chronic liver disease in a general population setting. Non-invasive tests of liver fibrosis might provide a mechanism for earlier diagnosis. These tests have been extensively validated in the hospital setting but their performance in a general population setting is unclear. We did a systematic review of non-invasive tests used to stratify patients at risk of clinically significant liver disease in a general population setting and report the prevalence of chronic liver disease as defined by these tests...

Liver cirrhosis is one of the main causes of death and disability-adjusted life-years worldwide. Generally, cirrhosis develops after a long period of liver-cell injury that leads to the deposition of collagen, leading to progressive fibrosis and nodule formation in the liver tissue. Most patients are diagnosed in late stages when liver decompensation or liver cancer develops. The diagnosis is rarely made in early stages-when liver fibrosis is mild to moderate but cirrhosis is not yet established-because the disease is asymptomatic...

Fontan-associated liver disease (FALD) is a serious complication related to the chronically elevated venous pressure and low cardiac output of this abnormal circulation. However, diagnostic markers for this condition are limited. We hypothesized that specific tests for fibrosis developed for other chronic liver diseases would identify a higher prevalence of FALD than ultrasound and standard laboratory tests and that identified abnormalities would correlate with time post-Fontan. In this cross-sectional study, we assessed 19 children (average age 8...

OBJECTIVES: The accurate assessment of liver fibrosis is clinically important in patients with chronic hepatitis B (CHB). Blood tests and elastography are now widely used for the noninvasive diagnosis of liver fibrosis in CHB patients. The aim of this study was to develop a new and more accurate predictive model, which combines elastography data, serum biomarkers, and individual characteristics, to discriminate between CHB patients with and without significant liver fibrosis. METHODS: Two noninvasive methods, specifically, an ultrasound elastography technique termed acoustic radiation force impulse imaging (ARFI) and a blood test, were used to assess a cohort of 345 patients (estimation group, 218 patients; validation group, 127 patients) with CHB...
