Purpose To (a) evaluate the postsurgical prognostic implication of Liver Imaging Reporting and Data System (LI-RADS) categories primary liver cancers (b) determine performance LI-RADS version 2017 in differentiating hepatocellular carcinoma (HCC) from intrahepatic cholangiocarcinoma (IHCC) combined hepatocellular-cholangiocarcinoma (cHCC-CC) at gadoxetic acid-enhanced MRI. Materials Methods In this retrospective study, 194 patients with cirrhosis surgically proven single cancer (53 cHCC-CC,...

Purpose To determine the imaging features at gadoxetic acid–enhanced magnetic resonance (MR) of intrahepatic cholangiocarcinoma (IHCC) in a cirrhotic liver, with an emphasis on distinction between IHCC and hepatocellular carcinoma (HCC) comparison nodule enhancement patterns MR computed tomography (CT). Materials Methods The institutional review board approved this study waived requirement for informed consent. Gadoxetic CT images 72 consecutive patients (61 men; mean age, 56.6 years) 78...
To evaluate the frequency of hepatic arterial injury in 3110 patients who had undergone percutaneous transhepatic biliary drainage (PTBD) and assess risk factors for treatment outcome after transcatheter embolization.A total underwent 3780 PTBDs between January 2003 December 2008 were retrospectively assessed. This study was approved by Institutional Review Board. The incidence determined associated with it analyzed using univariate multiple logistic regression analyses. Hepatic angiography...
The aim of this study was to validate the Liver Imaging Reporting and Data System (LI-RADS) v2014 category 4 (LR-4) 5 (LR-5) criteria on gadoxetate disodium-enhanced magnetic resonance imaging (MRI) in patients with chronic liver disease.Between January December 2012, 300 disease who had hepatic nodules 3.0 cm or smaller at surveillance ultrasonography MRI were included. LI-RADS retrospectively assigned each nodule MRI. Final diagnosis assessed using pathologic only (operation core-needle...
Background Current Liver Imaging Reporting and Data System guidelines define the washout appearance of gadoxetic acid-enhanced MRI only during portal venous phase. Defining phase may lead to lower sensitivity for diagnosis hepatocellular carcinoma (HCC). Purpose To compare diagnostic performances three criteria HCC according phases which was determined. Materials Methods In this retrospective study, patients with a hepatic nodule detected at US surveillance from January December 2012...
Abstract Background & Aims We aimed to compare the performance of gadoxetic acid‐enhanced abbreviated MRI (AMRI)‐based surveillance and ultrasound‐only in high‐risk patients for hepatocellular carcinoma (HCC). Methods Prospectively recruited (>5% annual risk HCC) who underwent one three rounds complete (CMRI) ultrasound at 6‐months intervals were retrospectively analysed. AMRI consisted diffusion‐weighted, T2‐weighted, hepatobiliary phase imaging. The sensitivity, specificity,...
With recent advances in radiology, the detection of ground-glass nodules (GGNs) has become increasingly common. However, there still is no consensus on management, especially need for systemic lymph node (LN) dissection. The purpose this study was to evaluate surgical outcomes basis extent resection primary lesion and mediastinal LN dissection carefully suggest appropriate treatment strategies patients with pulmonary adenocarcinoma presenting as pure opacities.From January 2006 December...
