Diffusion-tensor fiber tractography: intraindividual comparison of 3.0-T and 1.5-T MR imaging.
PURPOSE To prospectively evaluate the depiction of brain fiber tracts at 3.0- versus 1.5-T diffusion-tensor (DT) fiber tractography performed with parallel imaging. MATERIALS AND METHODS… Expand
Susceptibility-Weighted Imaging at 3 Tesla Delineates the Optic Radiation
Objectives:Some white matter tracts, including the optic radiation (OR), have recently been reported to be delineated as low signal intensity bands (LSBs) on T2*-weighted images at 7 T, presumably… Expand
"Hot cross bun" sign in multiple system atrophy with predominant cerebellar ataxia: a comparison between proton density-weighted imaging and T2-weighted imaging.
OBJECTIVE To investigate whether proton density-weighted imaging can detect the "hot cross bun" sign in the pons in multiple system atrophy with predominant cerebellar ataxia significantly better… Expand
Corticospinal tract localization: integration of diffusion-tensor tractography at 3-T MR imaging with intraoperative white matter stimulation mapping--preliminary results.
Institutional review board approval and written informed consent were obtained. The purpose of this study was to prospectively validate usefulness of diffusion-tensor (DT) fiber tractography of the… Expand
Hyperintense dentate nucleus on unenhanced T1-weighted MR images is associated with a history of brain irradiation.
PURPOSE To assess the frequency of hyperintensity in the dentate nucleus on T1-weighted magnetic resonance (MR) images and to establish correlations between such hyperintensity and clinical factors,… Expand
MR contrast of ferritin and hemosiderin in the brain: comparison among gradient-echo, conventional spin-echo and fast spin-echo sequences.
OBJECTIVE To compare the magnetic resonance image contrasts due to ferritin and hemosiderin in the brain tissue among different pulse sequences. MATERIALS AND METHODS Fourteen patients with… Expand
Comparison of 3.0- and 1.5-T three-dimensional time-of-flight MR angiography in moyamoya disease: preliminary experience.
PURPOSE To prospectively compare 3.0- and 1.5-T three-dimensional (3D) time-of-flight (TOF) magnetic resonance (MR) angiography in patients with moyamoya disease, with special emphasis on the… Expand
Grading glial tumors with amide proton transfer MR imaging: different analytical approaches
AbstractAmide proton transfer (APT) magnetic resonance imaging is gaining attention for its capability for grading glial tumors. Usually, a representative slice is analyzed. Different definitions of… Expand
Liliequist membrane: three-dimensional constructive interference in steady state MR imaging.
PURPOSE To evaluate the Liliequist membrane in healthy volunteers by using three-dimensional (3D) Fourier transformation constructive interference in steady state (CISS) magnetic resonance (MR)… Expand
