OBJECTIVE To investigate whether integrated fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) can differentiate benign from adrenal malignant lesions on the basis of maximum standardized uptake value (SUV(max)), tumor/liver (T/L) SUV(max) ratio, and CT attenuation value (Hounsfield Units; HU) of unenhanced CT obtained from(More)
PURPOSE The purpose of this study was to evaluate the accuracy of T-staging of gastric cancer by air-filling multidetector-row CT (air-MDCT) compared with water-filling MDCT (hydro-MDCT). MATERIALS AND METHODS One hundred fifteen patients with histologically diagnosed gastric cancer were included in this study. Fifty-eight patients underwent air-MDCT, and(More)
OBJECTIVE The objective of our study was to evaluate diagnostic ability and features of quantitative indices of three modalities: uptake rate on norcholesterol scintigraphy, computed tomography (CT) attenuation value, and fat suppression on chemical-shift magnetic resonance imaging (MRI) for characterizing adrenal adenomas. METHODS Image findings of(More)
OBJECTIVE The purpose of this study was to evaluate the effectiveness of contrast harmonic sonographic guidance in radiofrequency ablation of locally progressive hepatocellular carcinoma poorly depicted with B-mode sonography. SUBJECTS AND METHODS A series of 40 patients with hepatocellular carcinoma with local tumor progression poorly depicted with(More)
OBJECTIVES The purpose of this study was to investigate the usefulness of T1W black-blood Cube (BB Cube) and T1W BB Cube fluid-attenuated inversion recovery (BB Cube-FLAIR) sequences for contrast-enhanced brain imaging, by evaluating flow-related artefacts, detectability, and contrast ratio (CR) of intracranial lesions among these sequences and T1W-SE.

PURPOSE A prospective trial of concurrent chemoradiotherapy (CT-RT) with a protracted infusion of 5-fluorouracil and cisplatin was performed to evaluate the safety and efficacy of this protocol for T4 esophageal cancer (UICC 1997). METHODS AND MATERIALS Between 1998 and 2000, 28 patients with T4 esophageal squamous cell carcinomas were treated with(More)
PURPOSE To prospectively evaluate aortic and hepatic enhancement and depiction of hypervascular hepatocellular carcinoma (HCC) between two contrast materials with moderate and high iodine concentrations when administered at same iodine dose and injection duration at multi-detector row helical computed tomography (CT). MATERIALS AND METHODS Institutional(More)
This report describes the long-term operative outcome of 72 patients with spina bifida cystica. The period of follow-up was between 4 and 20 years. In our series, 17 patients died, with the mortality rate increasing as the lesions were more rostral. All cases involving only a meningocele are living without handicap. The cases of spina bifida cystica with(More)
This report describes long-term operative outcome of 24 cases with occipital encephalocele. The follow-up periods are between 4 and 20 years. Of the 24 patients with occipital encephalocele, two have died. Of the 22 living patients, 16 are living without neurological deficit, while six are disabled mentally and/or physically. Four cases of encephalocele(More)
PURPOSE New tracking navigation imaging software was used to evaluate the usefulness of three dimensional (3D) CT angiography for transcatheter arterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS Fifty-two patients with 73 HCCs were enrolled in this study retrospectively. Rotational angiography was(More)
