PURPOSE: To evaluate acute stroke with conventional, multisection diffusion-weighted (DW),
and hemodynamically weighted (HW) magnetic resonance (MR) imaging. MATERIALS …

Currently, the most widely used criteria for assessing response to therapy in high-grade
gliomas are based on two-dimensional tumor measurements on computed tomography (CT) or …

PURPOSE: To investigate additional information provided by maps of relative cerebral
blood flow in functional magnetic resonance (MR) imaging of human hyperacute cerebral …

PURPOSE: To (a) determine the optimal choice of a scalar metric of anisotropy and (b)
determine by means of magnetic resonance imaging if changes in diffusion anisotropy occurred …

The abnormal vasculature of the tumor microenvironment supports progression and resistance
to treatment. Judicious application of antiangiogenic therapy may normalize the structure …

Cortical spreading depression (CSD) has been suggested to underlie migraine visual aura.
However, it has been challenging to test this hypothesis in human cerebral cortex. Using high…

Despite aggressive surgery, radiotherapy and chemotherapy, malignant gliomas remain
uniformly fatal. To progress, these tumours stimulate the formation of new blood vessels through …

Measurement of vessel caliber by magnetic resonance imaging (MRI) is a valuable technique
for in vivo monitoring of hemodynamic status and vascular development, especially in the …

Regular, evidence‐based assignment of patients to etiologic stroke categories is essential
to enable valid comparison among studies. We designed an algorithm (SSS‐TOAST) that …

Mutations in the gene isocitrate dehydrogenase 1 (IDH1) are present in up to 86% of grade
II and III gliomas and secondary glioblastoma. Arginine 132 (R132) mutations in the enzyme …
