Cerebral infarctions in the anterior cerebral artery (ACA) territory account for only up to 3–5% of strokes. Subject to the affected ACA branches, different clinical patterns can be defined. We report a case series of patients with isolated infarctions of the pericallosal (PC) artery territory. We analyzed 36 consecutive patients presenting over a 10-year(More)
UNLABELLED Background- Small capsular strokes are difficult to assess with regard to the precise location and the extent of pyramidal tract damage with conventional brain imaging. Color-coded diffusion tensor imaging (CDTI) provides a means to visualize the course of the corticospinal tract within the white matter. In addition to T2-weighted MRI,(More)
BACKGROUND AND PURPOSE MRI studies have focused on newly developing MS lesions to characterize the early pathology of the disease. DWI is highly sensitive to acute and chronic tissue changes in MS. We characterized the development of acute MS lesions by using DWI in a multiparametric MRI protocol. MATERIALS AND METHODS Seventy-two consecutive patients(More)
Age-related white matter changes (ARWMC) appear to correspond to a continuum from normal functioning to clinically overt neurological syndromes. Disturbance of the structural integrity of cerebral fibre tracts—the so-called cerebral network—by ARWMC might be one explanation for this development. From 3 T magnetic resonance imaging (MRI) data of 34 healthy(More)
BACKGROUND Recovery from stroke is presumed to be a function of a widespread cerebral network. Chronic white matter lesions (WML) have been proposed to be a predictor of poor outcome after acute stroke. We tested the hypothesis that the extent of WML has an effect on functional recovery in acute pontine stroke by disrupting the integrity of the(More)
BACKGROUND Advanced magnetic resonance imaging (MRI) techniques provide a window into pathological processes in multiple sclerosis (MS). Nevertheless, to date only few studies have performed sodium MRI in MS. OBJECTIVES We analysed total sodium concentration (TSC) in hyperacute, acute and chronic lesions in MS with (23)Na MRI. METHODS (23)Na MRI and(More)
Sirs: Foix-Chavany-Marie syndrome (FCMS) presents with anarthria and bilateral central facio-linguo-velo-pharyngeo-masticatory paralysis with “automatic voluntary dissociation”, first described by Foix and Chavany in 1926 [3]. The most common cause of FCMS is cerebrovascular disease, while rarer causes include central nervous system infection, developmental(More)
OBJECTIVE To study the site of the ischemic lesion, the underlying cause, and the prognosis of acute stroke with distal arm paresis. METHOD The authors investigated 14 consecutive patients with acute distal arm paresis with a diagnostic stroke protocol and early MRI, including T2-weighted images, diffusion-weighted images (DWI), and perfusion-weighted(More)
The standard diffusion tensor model is limited in its ability to provide detailed information about multidirectional fiber architecture in human white matter. Additional directional acquisition of diffusivity properties with high angular resolution diffusion-weighted imaging (HARDI) acquisition schemes may deliver more information on areas with fiber(More)
