REVIEW
Iliana Doycheva, Kymberly D Watt, Naim Alkhouri
Nonalcoholic fatty liver disease (NAFLD) is a significant health burden in adolescents and young adults (AYAs) with substantial rise in prevalence over the last decades. This parallels high rates of obesity and metabolic syndrome in this age group, with unhealthy lifestyle also playing an independent role. Genetic factors, gender, and ethnicity should be considered in a risk stratification model. NAFLD and nonalcoholic steatohepatitis (NASH) in AYAs often go unrecognized and if untreated, can progress eventually to cirrhosis requiring liver transplantation before the age of 40...

This paper proposes a computer-aided cirrhosis diagnosis system to diagnose cirrhosis based on ultrasound images. We first propose a method to extract a liver capsule on an ultrasound image, then, based on the extracted liver capsule, we fine-tune a deep convolutional neural network (CNN) model to extract features from the image patches cropped around the liver capsules. Finally, a trained support vector machine (SVM) classifier is applied to classify the sample into normal or abnormal cases. Experimental results show that the proposed method can effectively extract the liver capsules and accurately classify the ultrasound images...

Qibing Zhou, Yushuang Wei
Superparamagnetic iron oxide nanoparticles (SPIONs) have recently been used as an effective magnetic resonance imaging (MRI) contrast agent for the noninvasive diagnosis of chronic liver diseases including nonalcohol fatty liver diseases, nonalcohol steatohepatitis, and cirrhosis as well as liver tumors. However, the potential risk of the iron overload by SPIONs has been highly underestimated in chronic liver diseases. While most of SPIONs have been shown safe in the healthy group, significant toxicity potential by the iron overload has been revealed through immunotoxicity, lipid peroxidation, and fatty acid and cholesterol metabolism in cirrhosis as a high risk factor...

BACKGROUND: The incidence of HCC continues to increase dramatically worldwide. Liver transplantation (LT) is now standard and optimal treatment for patients with HCC in the setting of cirrhosis, but only for tumors within Milan criteria (MC). In patients presenting beyond Milan, locoregional therapy (LRT) may downstage to within-Milan for consideration of LT. While controversial, the current study aims to evaluate the outcomes of LT in patients presenting with advanced stage HCC who underwent downstaging and compare to patients who meet Milan criteria at presentation...

BACKGROUND AND AIM: There still lacks a tool for precisely evaluating cirrhotic remodeling. Histologic distortion characterized in cirrhosis (i.e. cirrhotic patterns) has a validated pathophysiological meaning and the potential relevance to clinical complications. We aimed to establish a new tool for quantify the cirrhotic patterns and test it for reflecting the cirrhotic remodeling. METHODS: We designed a computerized algorithm (qCP) dedicated for the analysis of liver images acquired by second harmonic microscopy...

Up to now, there are no reliable biochemical markers or imaging that could reveal early tissue damage in Gaucher disease. Therefore, we addressed whether elastography technique can serve as a tool for evaluating patients with Gaucher disease. The study included 42 patients with Gaucher disease type I and 33 patients with liver cirrhosis as well as 22 healthy volunteers. Ultrasound and Doppler examination was performed on each participant prior to apply transient and 2D shear wave elastography. In Gaucher disease the median stiffness of the spleen as assessed by transient elastography (TE) and shear wave elastography (SWE) was 35KPa and 22KPa respectively in contrast to the median stiffness of healthy controls (16...

BACKGROUND: Alcoholic hepatitis and cirrhosis although part of spectrum of alcoholic liver disease can have overlapping features, and differentiating them using clinical, biochemical, and imaging features is not always possible. Standard therapy for each differs, and steroid therapy while beneficial in alcoholic hepatitis may be detrimental in cirrhosis due to high infectious complications. We analyzed our experience with liver biopsy in patients with severe alcoholic hepatitis. METHODS: Male patients in the age group of 25-65 years who were clinically diagnosed with severe alcoholic hepatitis (DF > 32) were retrospectively analyzed and included in this study...

Autoimmune hepatitis (AIH) is an uncommon, chronic inflammatory, and relapsing liver disease of unknown origin that may lead to liver cirrhosis, hepatocellular carcinoma, liver transplantation, or death. AIH occurs in all age groups and races but can frequently manifest as acute fulminant hepatitis. Clinical presentation of AIH can have features similar to primary sclerosing cholangitis (PSC) and primary biliary cirrhosis (PBC), and these diseases may coexist leading to overlap syndromes. Although histological diagnosis is necessary, imaging features often can demonstrate characteristics that may be helpful to distinguish these diseases...

Gadoxetic acid is extensively used in the following 3 main clinical situations: characterization of small nodules in patients with cirrhosis, preoperative staging of liver metastases, and characterization of incidentally discovered focal liver lesions. Owing to the rapid entry of gadoxetic acid into hepatocytes, the traditional features of liver tumors are modified on magnetic resonance (MR) imaging, especially during delayed phase sequences. Thus, although the added value of gadoxetic acid for the detection and characterization of focal liver lesions is now clear, its unique pharmacokinetics as well as the presence of mimicking and atypical lesions may lead to misdiagnoses...

Liver function assessment by hepatocyte-specific contrast-enhanced magnetic resonance imaging is becoming a new biomarker. Liver function can be assessed by T1 mapping (reduction rate) and signal intensity measurement (relative enhancement ratio) before and after GD-EOB-DTPA (gadoxetic acid) administration, as alternative to Tc-99m galactosyl serum albumin scintigraphy, 99m Tc-labeled mebrofenin scintigraphy, and indocyanine green clearance test. Magnetic resonance imaging assessment of liver function can enable diagnosis of cirrhosis, nonalcoholic fatty liver disease associated fibrosis and steatohepatitis, primary sclerosing cholangitis, toxic hepatitis, and chemotherapy and radiotherapy-related changes, which may be only visible on hepatobiliary phase images...
