Interferon-β (IFN-β) stabilizes the blood-brain barrier (BBB) in vitro. Here we investigated the effect of serum from 15 IFN-β-1b-treated multiple sclerosis (MS) patients on the permeability read-outs of small solutes in an in vitro BBB model consisting of human brain microvascular endothelial cells in co-culture with rat astrocytes. The addition of sera from IFN-β-treated patients resulted in a significantly (p < 0.

We reassessed this hypothesis in a case-control study by means of an improved semiautomated MR imaging technique. We compared the length of the cervical arteries in patients with and without sCAD.

Usually the deformity appears between the age of 8 and 14 years, often progressing from initially mild functional pain to fatigue and loss of strength and finally, reduced mobility. We present the MR-findings in three patients with bilateral MD, using a high-resolution imaging protocol adapted for 3.

The aim of the study was to describe the sonographical course of the affected arteries in patients with a MRI-proven sCAD by repetitive nUS.
Methods: Thirty-seven consecutive patients aged<60 years with 1.
Rationale And Objectives: The magnitude of iron-induced susceptibility changes in gradient echo T2*-weighted magnet resonance imaging (T2* MRI) increases with the field strength and should increase the sensitivity for detection of cerebral microbleeds (CMBs) at 3.0 T. To test these hypotheses, we prospectively examined individuals with documented CMBs at 1.

However, CAD is a highly dynamic process with rapid changes over time. Aim of this study was to assess the short-term morphologic changes in patients with proven CAD by MRI within 2 weeks after the initial diagnosis using a multicontrast high-resolution noninvasive vessel wall imaging approach at 3.

View Article and Find Full Text PDFPurpose: Magnetic Resonance Imaging (MRI) has become the method of choice in the evaluation of patients with suspected cervical artery dissection (CAD). However, reliable identification of acute CAD might be impaired by the limited spatial resolution of standard 1.5 T MRI.
