Fiber density index correlates with reduced fractional anisotropy in white matter of patients with glioblastoma.
A quantitative description of white matter fiber attenuation, the fiber density index (FDi) is described. This measure is derived from quantitative analysis of diffusion tensor imaging and reveals anExpand

Prediction of hemorrhage in acute ischemic stroke using permeability MR imaging.
Increased risk of hemorrhagic transformation (HT) limits the general use of thrombolytic therapy in acute ischemic stroke (AIS). This study shows that early blood-brain barrier defects in AIS can beExpand

Selective Reduction of Blood Flow to White Matter During Hypercapnia Corresponds With Leukoaraiosis
Background and Purpose— Age-related white matter disease (leukoaraiosis) clusters in bands in the centrum semiovale, about the occipital and frontal horns of the lateral ventricles, in the corpusExpand

Recombinant Tissue Plasminogen Activator Increases Blood-Brain Barrier Disruption in Acute Ischemic Stroke: An MR Imaging Permeability Study
BACKGROUND AND PURPOSE: Although thrombolytic therapy (recombinant tissue plasminogen activator [rtPA]) represents an important step forward in acute ischemic stroke (AIS) management, there is aExpand

Developmental trajectories of cerebrovascular reactivity in healthy children and young adults assessed with magnetic resonance imaging.
KEY POINTS Cerebrovascular reactivity (CVR) reflects the vasodilatory reserve of cerebral resistance vessels. Normal development in children is associated with significant changes in blood pressure,Expand

Contrast‐enhanced 3D MRA using SENSE
Sensitivity encoding (SENSE) was used to improve the performance of three‐dimensional contrast‐enhanced magnetic resonance angiography (3D CE‐MRA). Utilizing an array of receiver coils forExpand

Abnormalities in the recirculation phase of contrast agent bolus passage in cerebral gliomas: comparison with relative blood volume and tumor grade.
BACKGROUND AND PURPOSE Abnormalities in the recirculation phase of the passage of a contrast agent bolus have been identified in tumors and have been suggested to represent vascular tortuosity andExpand
