Intra-individual comparison of liver stiffness measurements by magnetic resonance elastography and two-dimensional shear-wave elastography in 888 patients.

Purpose: Quantitative elastography methods, such as ultrasound two-dimensional shear-wave elastography (2D-SWE) and magnetic resonance elastography (MRE), are used to diagnose liver fibrosis. The present study compared liver stiffness determined by 2D-SWE and MRE within individuals and analyzed the degree of agreement between the two techniques.

Methods: In total, 888 patients who underwent 2D-SWE and MRE were analyzed.

Prediction of Hepatocellular Carcinoma by Liver Stiffness Measurements Using Magnetic Resonance Elastography After Eradicating Hepatitis C Virus.

Introduction: Liver fibrosis stage is one of the most important factors in stratifying the risk of developing hepatocellular carcinoma (HCC). We evaluated the usefulness of liver stiffness measured by magnetic resonance elastography (MRE) to stratify the risk of developing HCC in patients who underwent MRE before receiving direct-acting antivirals (DAAs) and subsequently achieved sustained virological response (SVR).

Methods: A total of 537 consecutive patients with persistent hepatitis C virus who underwent initial MRE before DAA therapy and achieved SVR were enrolled.

Attenuation imaging based on ultrasound technology for assessment of hepatic steatosis: A comparison with magnetic resonance imaging-determined proton density fat fraction.

Aim: A new method has recently been developed for diagnosing hepatic steatosis based on attenuation measurement using ultrasound. We investigated the ability of attenuation imaging (ATI) to detect steatosis that was identified by proton density fat fraction (PDFF) on magnetic resonance imaging (MRI) in patients with chronic liver disease.

Methods: A total of 119 patients with chronic liver disease (non-B, non-C) were analyzed.

Impact of the introduction of direct-acting anti-viral drugs on hepatocarcinogenesis: a prospective serial follow-up MRI study.

Background: We conducted a prospective study using gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-MRI) to determine whether sustained virological response (SVR) by direct-acting anti-viral (DAA) drugs suppresses hepatocarcinogenesis in patients with hepatitis C virus (HCV) infection.

Aim: To use serial Gd-EOB-MRI to assess the impact of DAAs on hepatocarcinogenesis.

Methods: Between February 2008 and December 2018, 1083 consecutive patients with HCV infection underwent Gd-EOB-MRI.

Evaluation of pathological features of hepatocellular carcinoma by contrast-enhanced ultrasonography: comparison with pathology on resected specimen.

Features of hepatocellular carcinoma (HCC) observed by contrast-enhanced ultrasonography (CEUS) were compared to pathological features of corresponding resected HCC specimens, to evaluate the ability of CEUS to depict the pathological features of HCC. We investigated 50 HCC nodules that were treated by surgical resection. All nodules had been examined by CEUS with intravenous contrast agent (Levovist) before surgery.

Comparison of IV contrast-enhanced sonography and histopathology of pancreatic cancer.

Objective: We compared contrast-enhanced sonography findings with pathologic findings in pancreatic cancer to evaluate the ability of contrast-enhanced sonography to depict the pathologic changes associated with pancreatic cancer.

Subjects And Methods: Thirty-four patients with pancreatic cancer who underwent surgery were investigated. Sonography was performed with contrast material (Levovist) for all patients before surgery.

Assessment of tumor hemodynamics in small hepatocellular carcinoma: comparison of Doppler ultrasonography, angiography-assisted computed tomography, and pathological findings.

Aim: We evaluated the usefulness of Doppler ultrasonography (DUS) for the analysis of tumor hemodynamics in small hepatocellular carcinoma (HCC).

Methods: We compared Doppler ultrasound (DUS) findings with angiography-assisted computed tomography (Angio-CT) such as CT during arterial portography and during hepatic arteriography in the evaluation of the intratumoral hemodynamics, and with pathologic findings in 45 small HCC nodules (< or =3.0 cm in diameter) of 43 patients.

Comparison of contrast-enhanced harmonic ultrasonography and power Doppler ultrasonography for depicting vascularity of hepatocellular carcinoma identified by angiography-assisted CT.

The sensitivity of contrast-enhanced harmonic gray scale imaging was compared with that of power Doppler sonography in depicting tumor vascularity and contrast enhancement of hepatocellular carcinoma (HCC) identified by angiography-assisted computed tomography (CT). One hundred thirty-nine classic HCC nodules (108 patients), each appearing as a high-attenuation mass on early-phase CT during hepatic arteriography and as a perfusion defect on CT during arterial portography, were evaluated. Vascular findings and contrast enhancement patterns were evaluated by contrast-enhanced harmonic gray scale imaging.

Clinical utility of doppler ultrasonography in evaluation of early therapeutic efficacy after transcatheter arterial embolization in patients with hepatocellular carcinoma.

This study was undertaken to determine the value of Doppler ultrasonography in the early evaluation of therapeutic efficacy of hepatocellular carcinoma after transcatheter arterial embolization (TAE). Fifty-two nodules in which tumor vascularity had been detected by Doppler ultrasonography before TAE were examined in 41 patients. Doppler signals were evaluated 1 week after TAE, and the results were compared with tumor vascularity as determined by dynamic magnetic resonance imaging (dynamic MRI), which was used as the gold standard.
