PURPOSE To compare the neurodevelopmental outcomes between preterm infants with diffuse excessive high signal intensity (DEHSI) and those without DEHSI on magnetic resonance (MR) images, in association with other white matter lesions. MATERIALS AND METHODS This retrospective study was approved by the institutional review board, and requirement to obtain(More)
BACKGROUND AND PURPOSE A convoluted cerebriform pattern (CCP) has been reported as a valuable MR imaging feature of inverted papilloma (IP). The purpose of this study was to validate the usefulness of CCP for distinguishing IP from various malignant sinonasal tumors in a relatively large number of patients. MATERIALS AND METHODS We retrospectively(More)
BACKGROUND To evaluate the triple-phase CT findings for the differentiation of fat-deficient angiomyolipoma from hepatocellular carcinoma in non-cirrhotic liver. METHODS We retrospectively reviewed contrast-enhanced triple-phase CT images of 10 patients with fat-deficient hepatic angiomyolipoma and 28 patients with 29 hepatocellular carcinomas in(More)
PURPOSE To evaluate the accuracy of pre-operative MRI for the detection of optic nerve invasion in retinoblastoma. MATERIALS AND METHODS Institutional review board approval and informed consent were waived for this retrospective study. A total of 41 patients were included. Inclusion criteria were histologically proven retinoblastoma, availability of(More)
OBJECTIVE We analyzed the diffusion and perfusion characteristics of acute MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episode) lesions in a large series to investigate the controversial changes of the apparent diffusion coefficient (ADC) that were reported in prior studies. MATERIALS AND METHODS We analyzed 44 newly(More)
OBJECTIVE To evaluate the prevalence of incidentally found unruptured intracranial aneurysms (UIAs) on the brain MR angiography (MRA) from a community-based general hospital. MATERIALS AND METHODS This was a prospectively collected retrospective study, carried out from January 2004 to December 2004. The subjects included 3049 persons from a(More)
To evaluate the value of the gadobenate dimeglumine-enhanced hepatobiliary-phase magnetic resonance (MR) imaging for the differentiation of scirrhous hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) with or without HCC. We retrospectively evaluated unenhanced and gadobenate dimeglumine-enhanced dynamic and hepatobiliary-phase MR images of five(More)
AIM To evaluate the association between computed tomography (CT) detection of early gastric cancer (EGC) and various parameters, including the depth of invasion, lesion extent, morpholgical type, location, and histological type. MATERIALS AND METHODS One hundred and ten patients with 114 EGCs were preoperatively examined using multidetector CT (MDCT). All(More)
BACKGROUND In a previous study, we reported that serpin peptidase inhibitor clade A member 1 (serpinA1) is upregulated in Snail-overexpressing gastric cancer. Although serpinA1 has been studied in several types of cancer, little is known about its roles and mechanisms of action. In this study, we examined the role of serpinA1 in the migration and invasion(More)
Gadobenate dimeglumine-enhanced magnetic resonance (MR) imaging simultaneously provides both morphological and functional information by the acquisition of dynamic and hepatobiliary-phase imaging. Focal lesions with no functioning hepatocytes, where hepatobiliary metabolism is blocked or inhibited, are generally unable to uptake and excrete gadobenate(More)
