Comparison of Magnetic Properties of MRI Contrast Media Solutions at Different Magnetic Field Strengths
Rationale and Objectives:To characterize and compare commercially available contrast media (CM) for magnetic resonance imaging (MRI) in terms of their relaxivity at magnetic field strengths rangingExpand
Early detection of regional cerebral ischemia in cats: Comparison of diffusion‐ and T2‐weighted MRI and spectroscopy
Diffusion‐weighted MR images were compared with T2‐weighted MR images and correlated with 1H spin‐echo and 31P MR Spectroscopy for 6‐8 h following a unilateral middle cerebral and bilateral carotidExpand
Diffusion-weighted MR imaging of anisotropic water diffusion in cat central nervous system.
The diffusion behavior of intracranial water in the cat brain and spine was examined with the use of diffusion-weighted magnetic resonance (MR) imaging, in which the direction of theExpand
Diffusion-weighted MR imaging of acute stroke: correlation with T2-weighted and magnetic susceptibility-enhanced MR imaging in cats.
We evaluated the temporal and anatomic relationships between changes in diffusion-weighted MR image signal intensity, induced by unilateral occlusion of the middle cerebral artery in cats, and tissueExpand
Comparison of diffusion‐ and T2‐weighted MRI for the early detection of cerebral ischemia and reperfusion in rats
The sensitivity of diffusion‐weighted MRI was compared to that of T2‐weighted MRI following temporary middle cerebral artery occlusion (MCA‐0) for 33 min followed by 4 h of reperfusion in rats.Expand
Cytotoxic brain edema: assessment with diffusion-weighted MR imaging.
To determine whether cytotoxic brain edema is associated with a decrease in diffusion, it was induced in rats, in the absence of ischemia, with an established model of acute hyponatremicExpand
Early detection of ischemic injury: comparison of spectroscopy, diffusion-, T2-, and magnetic susceptibility-weighted MRI in cats.
Within one hour following MCA-occlusion in cats, heavily diffusion-weighted spin-echo MR images exhibited a well-defined hyperintensity in the gray matter and basal ganglia of the occluded side overExpand
Diffusion-Weighted Magnetic Resonance Imaging of Acute Focal Cerebral Ischemia: Comparison of Signal Intensity with Changes in Brain Water and Na+,K+ -ATPase Activity
Diffusion-weighted magnetic resonance (MR) images from rats during acute cerebral ischemia induced by middle cerebral artery occlusion were analyzed for correspondence with changes in brain water,Expand
Echo-planar perfusion-sensitive MR imaging of acute cerebral ischemia.
T2*-sensitive echo-planar magnetic resonance imaging was used with first-pass magnetic susceptibility contrast enhancement in a cat model of acute regional stroke to evaluate the relationship betweenExpand
Quantification of tissue plasma volume in the rat by contrast‐enhanced magnetic resonance imaging
Magnetic resonance imaging enhanced with a macromolecular contrast medium (MMCM), albumin‐Gd‐DTPA, was used to estimate the plasma volume in vivo in the myocardium, lung, liver, and skeletal muscleExpand
