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)
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)
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)
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)
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)
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 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)
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)
AIM To investigate the value of diffusion-weighted imaging (DWI) for differentiating benign from malignant gallbladder lesions. MATERIALS AND METHODS One hundred and twenty-six patients who had undergone magnetic resonance imaging (MRI) with DWI, in whom the histopathological diagnosis of their gallbladder lesions was confirmed by biopsy or surgery were(More)
PURPOSE Our aim was to retrospectively review the imaging findings of patients with neonatal ovarian torsion, emphasizing prenatal and postnatal sonographic findings. METHODS Eleven patients who had had neonatal ovarian torsion diagnosed surgically (n = 9) or clinicoradiologically (n = 2) were enrolled. Prenatal and postnatal sonographic features,(More)
