Objective: This study was performed to determine whether neoadjuvant treatment increases survival in patients with BRPC. Summary Background Data: Despite many promising retrospective data on the effect of for borderline resectable pancreatic cancer (BRPC), no high-level evidence exists support role such treatment. Methods: phase 2/3 multicenter randomized controlled trial designed enroll 110 BRPC who were randomly assigned gemcitabine-based chemoradiation (54 Gray external beam radiation)...
To investigate the added value of diffusion-weighted (DW) magnetic resonance (MR) imaging in evaluation complete response (CR) to neoadjuvant combined chemotherapy and radiation therapy (CRT) patients with locally advanced rectal cancer.Institutional review board approval was obtained for this retrospective study, patient informed consent requirement waived. Forty consecutive cancer (>or=T3 or lymph node positive) who underwent CRT subsequent surgery were enrolled study. All pre- post-CRT...
Purpose To evaluate the long-term outcomes of radiofrequency ablation (RFA) as a first-line therapy for early-stage hepatocellular carcinoma (HCC) and determine prognostic factors survival. Materials Methods The institutional review board approved this retrospective study. From January 2006 to December 2007, 162 consecutive patients with cirrhosis (Child-Pugh class A B, 137 25 patients, respectively) who underwent RFA treatment up three HCCs maximum diameter 5 cm (182 HCCs; mean ± standard...
Purpose To evaluate the enhancement patterns, prevalence of secondary signs, and histopathologic features 20-mm-diameter or smaller pancreatic cancers seen on multiphasic multidetector computed tomographic (CT) images. Materials Methods This retrospective study was approved by institutional review board; requirement for informed consent waived. From January 2002 through September 2009, authors reviewed clinical imaging data 130 consecutive patients (76 men, 54 women; mean age, 64.1 years;...
We present an ultraconcentrated electrolyte composed of 5 M sodium bis(fluorosulfonyl)imide in 1,2-dimethoxyethane for Na metal anodes coupled with high-voltage cathodes. Using this electrolyte, a very high Coulombic efficiency 99.3% at the 120th cycle plating/stripping is obtained Na/stainless steel (SS) cells highly reduced corrosivity toward and oxidation durability (over 4.9 V versus Na/Na+) without corrosion aluminum cathode current collector. Importantly, use results substantially...
The maritime industry is undergoing rapid digital transformation, with Maritime Autonomous Surface Ships (MASS) at the forefront, introducing unprecedented cybersecurity challenges. This study addresses critical research gaps by identifying high-risk equipment based on international classification society standards and proposing a framework to analyze mitigate vulnerabilities in MASS environments. Eight attack scenarios were designed using MITRE ATT&CK ICS framework, most scenario validated...
Although radio-frequency (RF) ablation has been accepted as a promising and safe technique for treatment of unresectable hepatic tumors, investigation its complications limited. According to the multicenter (1,139 patients in 11 institutions) survey data Korean Study Group Radiofrequency Ablation, spectrum occurred after RF tumors. The prevalence major was 2.43%. most common were abscess (0.66%), peritoneal hemorrhage (0.46%), biloma (0.20%), ground pad burn pneumothorax vasovagal reflex...
PURPOSE: To assess technical feasibility, efficacy, and complications of percutaneous computed tomography (CT)-guided transthoracic radiofrequency (RF) ablation for treating inoperable non–small cell lung cancer (NSCLC) metastases. MATERIALS AND METHODS: Twenty-six patients with 27 NSCLCs four five metastases underwent RF cooled-tip electrodes CT guidance. Patients were not candidates surgery because either advanced-stage disease (n = 20) and/or comorbid processes 4) or refusal to undergo...
To determine the characteristic enhancing features of hepatocellular carcinoma (HCC) and arterial-enhancing pseudolesion (AEP) on gadoxetic acid (Primovist)-enhanced magnetic resonance imaging (MRI) to assess its performance compared with that multirow detector computed tomography (MDCT) for differentiating small HCC (< or =2 cm in diameter) from AEP cirrhotic liver.A total 69 patients 97 small, arterial hepatic lesions (0.5-2 diameter), ie, 44 HCCs 53 AEPs, detected acid-enhanced MRI, were...
Purpose To evaluate the imaging features of intrahepatic mass-forming cholangiocarcinomas (IMCCs) at computed tomography (CT), with a special emphasis on degree and pattern arterial enhancement, to determine whether clinicopathologic IMCCs enhancement differ from those less enhancement. Materials Methods The institutional review board Seoul National University Hospital approved this retrospective study, informed patient consent was waived. Sixty-four patients 70 pathologically confirmed...
To retrospectively assess the accuracy of combined multiphasic computed tomography (CT) and direct cholangiography for evaluation resectability hilar cholangiocarcinoma, on basis revised criteria unresectability, by using surgery as reference standard.Institutional review board approval was obtained, informed consent waived. From 1998 to 2003, 55 patients (37 men, 18 women; mean age +/- standard deviation, 59 years 12) with surgically proved cholangiocarcinomas who underwent preoperative CT...
Purpose To compare the association of intravoxel incoherent motion (IVIM)–derived parameters and apparent diffusion coefficient (ADC) with histologic grade hepatocellular carcinoma (HCC) evaluate relationship between IVIM-derived arterial enhancement degree. Materials Methods This retrospective study was institutional review board–approved, informed consent waived. Forty patients 42 surgically confirmed HCCs underwent diffusion-weighted magnetic resonance (MR) imaging eight b values (0–800...
A foreign body granuloma is a non-allergic chronic inflammatory reaction that mainly composed of multinucleated giant cells. Foreign granulomas may occur after the administration any dermal filler. Factors such as volume injection, impurities present in fillers, and physical properties fillers affect formation. The formation involves five phases: protein adsorption, macrophage adhesion, fusion, crosstalk. clinical pathologic features vary depending on type filler causes them. can be treated...
To evaluate the enhancement patterns of intrahepatic mass-forming cholangiocarcinomas (IMCCs) with emphasis on hepatobiliary phase (HBP) gadoxetic acid-enhanced magnetic resonance (MR) imaging.This retrospective study was institutional review board approved, and requirement for informed consent waived. Fifty patients (41 men, nine women; mean age, 62.3 years; range, 44-76 years) IMCC underwent unenhanced T1- T2-weighted MR imaging including dynamic between May 2008 December 2010. Signal...
To investigate the patterns of imaging appearance hepatocellular carcinoma (HCC) on gadoxetic acid-enhanced magnetic resonance (MR) images and to assess their potential value as prognostic markers HCC associated with tumor recurrence after surgery.The institutional review board approved this retrospective study informed consent was waived. A total 216 patients 304 pathologically proved HCCs underwent MR prior surgery were included in study. Two reviewers, blinded clinical data, evaluated...
