BACKGROUND Positron emission tomography (PET) with 18- fluorodeoxyglucose (FDG) has been used to both detect and stage a variety of malignancies. The current study examined the value of PET for preoperative staging of gastric adenocarcinoma. METHODS Sixty-eight patients (49 males and 19 females) with gastric adenocarcinoma, who were referred for(More)
Fuzzy neural networks (FNNs) have been successfully applied to generate predictive rules for medical or diagnostic data. This brief presents an approach to detect premature ventricular contractions (PVCs) using the neural network with weighted fuzzy membership functions (NEWFMs). The NEWFM classifies normal and PVC beats by the trained bounded sum of(More)
PURPOSE To determine the added value of hepatobiliary phase images in gadoxetic acid-enhanced magnetic resonance (MR) imaging in the evaluation of hepatocellular carcinoma (HCC). MATERIALS AND METHODS Institutional review board approved this retrospective study and waived the informed consent. Fifty-nine patients with 84 HCCs underwent gadoxetic(More)
UNLABELLED This study was performed to compare (18)F-FDG PET with CT for the evaluation of primary tumors and lymph node metastases in gastric cancer. METHODS Eighty-one patients (28 women and 53 men; mean age, 56.6 y; age range; 32-82 y) who had undergone radical (n = 74) or palliative (n = 7) gastrectomy and lymph node dissection for the management of(More)
PURPOSE To evaluate the diagnostic accuracy of multidetector row computed tomography (MDCT) for the preoperative T- and N staging of gastric cancer. MATERIALS AND METHODS Eighty-four consecutive patients with gastric cancer underwent preoperative MDCT. Except for 15 patients who did not undergo surgery, 69 patients were included in our study. Two(More)
To assess whether reticular hypointensity on hepatobiliary phase images of gadoxetic acid-enhanced magnetic resonance imaging (EOB-MRI) is a diagnostic finding of sinusoidal obstruction syndrome (SOS) in patients with hepatic metastases who have undergone chemotherapy. We retrospectively analysed EOB-MRI of 42 patients who had undergone chemotherapy before(More)
To determine whether intravenous administration of gadoxetic acid disodium (Gd-EOB-DTPA) affects lesion conspicuity and apparent diffusion coefficient (ADCs) in diffusion-weighted imaging (DWI) for hepatic magnetic resonance imaging (MRI) at 3.0 T. Thirty-four patients with 50 focal hepatic lesions (18 hepatocellular carcinomas, 12 metastases, 1(More)
OBJECTIVE The purpose of this article is to present the typical and atypical manifestations of serous cystadenoma, which can be visualized with cross-sectional imaging. CONCLUSION Serous cystadenomas of the pancreas have various distinguishing imaging features. Typically, a serous cystadenoma is morphologically classified as having either a polycystic,(More)
OBJECTIVE Our objective was to determine the utility of 3D T2 MR cholangiography (MRC) for biliary visualization and predicting the number of ductal orifices during right lobe harvesting for ductal anastomosis in liver donors for right lobe transplantation. MATERIALS AND METHODS This study was composed of 33 donors who underwent right lobectomy for(More)
The aim of this study was to evaluate the impact of visceral fat obesity (VFO) on early surgical and oncologic outcomes of laparoscopic total mesorectal excision (LTME) for rectal cancer. Between June 2003 and June 2009, a total of 142 patients who had undergone LTME were included. Patients were divided into the obese group (OG) and the non-obese group(More)
