BACKGROUND AND PURPOSE: The extent of abnormalities on T2-weighted MR images of
the brain of patients with clinically isolated syndromes (CIS) suggestive of multiple sclerosis …

Objectives We used an optimized echo-planar pulse sequence for isotropically weighted
diffusion imaging (1) to measure mean diffusivity (D) in lesions and normal-appearing white …

Objective: To identify differences in pathology between the principal clinical phenotypes of
MS using conventional and magnetization transfer (MT) MRI. Methods: T1-weighted and T2-…

Previous studies assessing the magnetic resonance imaging (MRI) correlates of cognitive
dysfunction in multiple sclerosis (MS) achieved conflicting results. Diffusion tensor (DT)-MRI …

BACKGROUND AND PURPOSE: We assessed whether the extent of macro- and microscopic
disease in the cortical and subcortical brain tissue, as revealed by MR and magnetization …

Introduction We report the experiences of 25 Italian centers, analyzing intra- and periprocedural
complications of endovascular treatment of intracranial aneurysms using Silk (Balt …

BACKGROUND AND PURPOSE: In multiple sclerosis (MS), the severity of tissue damage
can vary from edema and inflammation to irreversible demyelination and axonal loss. …

Background Diffusion-tensor magnetic resonance imaging is sensitive to the more destructive
aspects of multiple sclerosis (MS) evolution occurring outside and within T2-visible lesions …

PURPOSE: To investigate the influence of aging on conventional magnetic resonance (MR)
imaging–, magnetization transfer MR imaging–, and diffusion-tensor MR imaging–derived …

Background Diffusion tensor magnetic resonance imaging (DT MRI) has the potential to
provide in vivo information about tissue microstructure. In multiple sclerosis (MS), DT MRI has …
