Purpose To determine whether hepatocyte uptake ratios derived at gadoxetic acid–enhanced MRI correlate with quantitative measures of liver function and can help to identify contraindication major hepatectomy. Materials Methods Between August 2016 October 2016, 50 study participants chronic disease or cirrhosis underwent 3.0 T including T1 mapping elastography. Liver was quantitatively assessed by using the indocyanine green retention test (ICG R15). maps were obtained Look-Locker sequence...
Ultrasonography (renamed from the Journal of Korean Society Ultrasound in Medicine January 2014), official English-language journal (KSUM), is an international peer-reviewed academic dedicated to practice, research, technology, and education dealing with medical ultrasound, Aims Scope:Ultrasonography ultrasound.It published four times per year: 1, April July October 1. Original articles, topical reviews, pictorial essays, notable case reports are covering state-of-the-art content. also...
Purpose To investigate the Liver Imaging Reporting and Data System (LI‐RADS) v2014 categorization of hepatocellular carcinomas (HCCs) on gadoxetic acid‐enhanced magnetic resonance imaging (Gd‐EOB‐MRI) in comparison with multiphasic multidetector computed tomography (MDCT). Materials Methods Our Institutional Review Board approved this retrospective study waived requirement for informed consent. We included 182 high‐risk patients 216 pathologically confirmed HCCs who underwent both Gd‐EOB‐MRI...
Background Few studies have reported on the diagnostic performance of Liver Imaging Reporting and Data System (LI-RADS) LR-5 or V in diagnosis hepatocellular carcinoma (HCC) using MRI with gadoxetate disodium. Purpose To determine LI-RADS version 2018 (hereafter, v2018) disodium-enhanced comparison 2017 v2017) for HCC patients cirrhosis chronic hepatitis B viral infection at high risk HCC. Materials Methods This retrospective study between January 2013 October 2015 evaluated consecutive who...
Background Accurate assessment of local resectability pancreatic cancer at initial workup is critical to determine the most appropriate management strategy among up-front operation, neoadjuvant treatment, or palliative treatment. Purpose To investigate interobserver agreement preoperative CT classification and if radiologist experience level impacts evaluation, evaluate reader performance in assessing a subset patients with reference standard for resectability. Materials Methods This...
Biannual ultrasonography (US) is a current recommendation for hepatocellular carcinoma (HCC) surveillance in high-risk group. The sensitivity of US, however, has been low patients with high risk developing HCC. We aimed to compare HCC biannual US and two-phase low-dose computed tomography (LDCT) HCC.In this prospective single-arm study, participants an annual greater than 5% (based on index ≥2.33) who did not have history were enrolled from November 2014 July 2016. Participants underwent...

To assess intra- and inter-observer reproducibility of a new point shear wave elastography technique (pSWE, S-Shearwave, Samsung Medison) compare its accuracy in assessing liver stiffness (LS) with an established pSWE (Virtual Touch Quantification, VTQ).Thirty-three patients were enrolled this Institutional Review Board-approved prospective study. LS values measured by VTQ on Acuson S2000 system (Siemens Healthineer) S-Shearwave RS-80A (Samsung the same session, followed two further sessions...
Objectives The aim of this study was to evaluate the clinical feasibility gadoxetic acid–enhanced isotropic high-resolution (IHR) 3-dimensional (3D) T1-weighted (T1W) magnetic resonance cholangiography (MRC) using an iterative denoising (ID) algorithm for evaluation biliary anatomy living liver donors in comparison with conventional 3D multislice T2-weighted (T2W) MRC. Materials and Methods In institutional review board–approved retrospective study, a total 75 who underwent T2W-MRC...
The aim of this study was to determine the value multi-detector row computed tomography (MDCT) in differentiating small-duct (SD) and large-duct (LD) types intrahepatic mass-forming cholangiocarcinomas (IMCCs) predicting patient prognosis.The 4-phase MDCT image findings 82 patients with surgically confirmed IMCCs (60 SD-type 22 LD-type IMCCs) were compared between 2 using univariate multivariate analyses. Overall survival rates for 78 available information Kaplan-Meier method.Arterial...
The purpose of this study was to compare the effect a multiloop edgewise archwire (MEAW) with plain ideal (IA) on distal en masse movement mandibular dentition. A three-dimensional finite element model (3D fem) dentition, without third permanent molars, constructed include periodontal membrane (pdm), alveolar bone, standard bracket (0.018 × 0.025 inch), stainless steel IA (0.016 0.022 and MEAW inch). Stress distribution displacement dentition were analyzed when Class III intermaxillary...
Abstract Background Little information is available on the use of chest computed tomography (CT) to predict breast tumor size in cancer, despite fact that CT examinations are being increasingly used. The purpose this study was evaluate value for predicting using pathology measurements as reference standards. Methods Tumor sizes (defined greatest diameter) were retrospectively measured preoperative images 285 patients with surgically proven unifocal, invasive carcinoma. Greatest diameters...
