An automated method for tree-ring delineation based on active contours guided by DT-CWT complex coefficients in photographic images: Application to Abies alba wood slice images

, 2015
International audienceThis paper describes an efficient method for delineating tree-rings and inter tree-rings in wood slice images. The method is based on an active contour approach and a multi-scale gradient map resulting from the Dual Tree Complex ...

Accuracy of the LI-RADS Criteria for Diagnosis of Hepatocellular Carcinoma in Noncirrhotic Patients with Chronic Hepatitis C : A Multicenter Data Analysis

Background and aims: Despite the known risk of HCC beyond chance, the LI-RADS criteria have not been validated for noncirrhotic patients with chronic hepatitis C (CHC). We aimed to evaluate the diagnostic performance of LR-5 observations for HCC in these

Combining the FIB-4 Index with the aMAP Score to Enhance Prediction of Liver Carcinogenesis in HCV-SVR Patients

Combining the FIB-4 Index with the aMAP Score to Enhance Prediction of Liver Carcinogenesis in HCV-SVR Patients
Background and aim: The background of liver carcinogenesis has shifted from viral hepatitis to sustained virological response (SVR) of hepatitis C virus (HCV) due to the advent of direct-acting antiviral agents (DAAs). The aMAP score is useful for predicting liver carcinogenesis in HCV-SVR patients, but limitations remain, particularly in medium- and ...
