BACKGROUND AND PURPOSE MR imaging, PET, and ictal SPECT have been studied extensively as individual techniques in the localization of epileptogenic foci, but only a few comparative studies have been done. We evaluated the concordance rates of ictal video/EEG, MR imaging, PET, and ictal SPECT to compare the sensitivities of these imaging methods in the(More)
We conducted a three-stage genome-wide association study (GWAS) of response to antidepressant drugs in an ethnically homogeneous sample of Korean patients in untreated episodes of nonpsychotic unipolar depression, mostly of mature onset. Strict quality control was maintained in case selection, diagnosis, verification of adherence and outcome assessments.(More)
RATIONALE AND OBJECTIVES The authors sought to correlate the radiologic findings of hepatobiliary fascioliasis with pathologic features. METHODS Serial ultrasound, computed tomography (CT), and magnetic resonance findings in seven rabbits with experimentally induced fascioliasis were obtained every other week. Direct cholangiogram was also obtained after(More)
PURPOSE To evaluate prospectively the usefulness of thin-section computed tomography (CT) in the prediction of biopsy-proved invasive pulmonary aspergillosis in patients with neutropenia. MATERIALS AND METHODS In 11 consecutively seen neutropenic patients, 12 open-lung biopsies were performed prospectively for suspected angioinvasive (n = 10) or(More)
BACKGROUND This study aimed to investigate whether radiofrequency ablation (RFA) is an alternative to surgical resection for hepatocellular carcinoma (HCC) within the context of current guidelines. METHODS This retrospective study included patients with normal portal pressure and serum bilirubin level who initially underwent liver resection or RFA for a(More)
AIM To retrospectively evaluate the efficacy of biphasic magnetic resonance imaging (MRI) of the liver with ferucarbotran-enhancement for the characterization of hepatic metastases. MATERIALS AND METHODS Thirty-six patients underwent MRI of the liver with separate acquisition of double-contrast enhancement consisting of gadolinium and ferucarbotran. A(More)
RATIONALE AND OBJECTIVES The authors evaluated changes of lung attenuation in pigs, with special attention to the mosaic pattern of low attenuation, at thin-section computed tomography (CT) after obstruction of the proximal pulmonary artery with a detachable balloon. MATERIALS AND METHODS In seven pigs, nine sites of the descending pulmonary artery were(More)
We aimed to develop a risk model, based on single-nucleotide polymorphism (SNP) markers associated with an increased risk of organ-specific GVHD in 394 transplant pairs. A total of 259 SNPs were genotyped in 53 genes and evaluated for their associated risk of organ-specific GVHD. Risk models were generated using both clinical factors and genetic SNP(More)
INTRODUCTION The response to acetylcholinesterase inhibitors (AChEIs) of Alzheimer's disease (AD) patients varies depending on the genetic characteristics of the patient. We have examined the association of response to AChEIs and genetic polymorphisms in AD patients. METHODS 158 patients with AD underwent treatment with AChEIs, and the therapeutic effect(More)
AIM To evaluate the efficacy and safety of internally cooled wet (ICW) electrodes, which provide interstitial infusion of saline and intra-electrode cooling simultaneously, in the percutaneous radiofrequency ablation (RFA) of liver metastases from colorectal cancer. MATERIALS AND METHODS From February 2008 to October 2010, 27 patients with 35 hepatic(More)
