To investigate CT features and differential diagnosis of pancreatic adenocarcinoma compared to other solid tumours arising in the periampullary area. One hundred and ninety-five patients with pathologically proven, solid periampullary tumours, including pancreatic adenocarcinoma (n = 98), neuroendocrine tumours (n = 52), gastrointestinal stromal tumours (n(More)
BACKGROUND/AIMS This study reviews the clinicopathological features, prognosis, and differences in the expression of p53 and Ki-67 immunochemical staining in squamous cell and adenosquamous carcinoma of the stomach. METHODS From January 1995 to June 2005, 2,282 cases of gastric carcinoma were resected surgically in our hospital and 191 additional cases(More)
The aim of this study was to compare the diagnostic performance of multidetector row helical CT (MDCT) and gadobenate dimeglumine-enhanced magnetic resonance (MR) imaging (in the detection and characterization of focal liver lesions. Two blind reviewers analyzed the MDCT and MR images of a total of 44 malignant and 85 benign lesions in 46 patients(More)
OBJECTIVE We wished to compare the in-vitro efficiency of wet radiofrequency(RF) ablation with the efficiency of dry RF ablation and RF ablation with preinjection of NaCl solutions using excised bovine liver. MATERIALS AND METHODS Radiofrequency was applied to excised bovine livers in a monopolar mode for 10 minutes using a 200 W generator and a(More)
OBJECTIVE To determine the optimized protocol for wet monopolar radiofrequency ablation (RFA) using a perfused-cooled electrode to induce coagulation necrosis in the ex vivo bovine liver. MATERIALS AND METHODS Radiofrequency was applied to excised bovine livers in a monopolar mode using a 200W generator with an internally cooled electrode (groups A and B)(More)
BACKGROUND/AIMS The purpose of this study was to evaluate clinical outcome of proximal and total gastrectomy regarding reflux esophagitis, nutritional state, and anemia in early gastric cancer. METHODS 94 patients with early gastric cancer were included from January 2001 to January 2007 at Chungnam National University Hospital. Of whom 40 patients (31 men(More)
OBJECTIVE We sought to determine whether hypertonic-saline (HS)-augmented bipolar radiofrequency ablation has advantages over monopolar radiofrequency ablation for creating larger areas of coagulation necrosis in the kidney. MATERIALS AND METHODS Using a 200-W generator and bipolar perfused-cooled electrodes or a monopolar cooled-tip electrode, we(More)
The aim of the study was to evaluate the acute adverse events rate and enhancement properties of gadoterate meglumine (Dotarem®) and gadobenate dimeglumine (MultiHance®) in a small-scale controlled double-blinded study, using inter- and intra-individual comparisons. Forty-one randomly selected patients were scanned with Dotarem®. The rate of adverse(More)
OBJECTIVE To assess the diagnostic performance of multidetector-row computed tomography (CT) 3-dimensional CT gastrography (3-D CTG) to detect early gastric cancer (EGC) compared with axial CT images alone. METHODS Contrast-enhanced multidetector-row CT scanning was performed on 39 patients with histopathologically proven EGC. By using volume-rendering(More)
cells which are widely distributed in the body. The sites most often affected by these tumors, in order of importance, are the gastrointestinal and bronchopulmonary tracts (1). However, primary neuroendocrine tumors in the presacral region are extremely rare. Even though there were a few reports about neuroendocrine tumor of the presacral region, to the(More)
