In this retrospective analysis we report our treatment experience in 65 consecutive patients with clinical signs of severe brainstem ischemia with angiographically demonstrated thrombotic vertebrobasilar artery occlusions who received either local intra-arterial thrombolytic therapy (urokinase or streptokinase) (43 patients) or conventional therapy(More)
BACKGROUND Carotid endarterectomy is effective in stroke prevention for patients with severe symptomatic carotid-artery stenosis, and carotid-artery stenting has been widely used as alternative treatment. Since equivalence or superiority has not been convincingly shown for either treatment, we aimed to compare the two. METHODS 1200 patients with(More)
Affective facial processing is an important component of interpersonal relationships, which is altered in patients with major depression. The study was designed to examine differences in functional brain activity between patients with major depression and healthy controls using functional magnetic resonance imaging (fMRI). Twelve patients with major(More)
Most functional imaging data are collected in single session experiments; little is known about the reproducibility or test-retest reliability of the activation patterns found in these experiments. In our study, 15 healthy volunteers performed four simple motor-paradigms ("Hand", "Foot", "Mouth" and "Tongue") for functional magnetic resonance imaging (fMRI)(More)
Cerebral amyloid angiopathy (CAA) is an important cause of intracerebral hemorrhage. Its definite diagnosis still requires histopathologic demonstration of vascular amyloid. Thus, further improvement of noninvasive imaging methods would be desirable. Here we present 3 patients with histologically proved CAA, in which superficial cortical hemosiderosis and(More)
The use of functional magnetic resonance imaging (fMRI) to examine mental imagery of locomotion has become an attractive way to investigate supraspinal gait control in humans. Whereas cerebral activation patterns associated with walking along a straight line have already been investigated, data on activations associated with the initiation of turns and the(More)
Since several years Mercedes-Benz integrates simulation and comprehensive tests with a high degree of automation in the development process of automatic transmissions. This process has been continuously improved and extended. Recently also first suppliers and engineering service providers have been integrated in this process. In this paper we present the(More)
BACKGROUND AND PURPOSE To evaluate predictors of recanalization and a favorable neurologic outcome in patients with acute vertebrobasilar occlusion (VBO) treated with local intra-arterial fibrinolysis (LIF). METHODS The multicentric data of 180 patients with acute VBO treated with LIF were retrospectively evaluated. The modified Rankin scale (mRS) was(More)
PURPOSE To determine CT findings in the external, middle, and inner ear of patients with microtia and external auditory canal dysplasia. METHODS We used high-resolution CT, with multiplanar or axial 1-mm continuous sections, coronal or sagittal reformations, or low-dose spiral acquisitions, to examine 184 temporal bones of children with microtia.

PURPOSE The reported outcomes of central retinal artery occlusion (CRAO) with or without treatment vary considerably. Although local intra-arterial fibrinolysis (LIF) using recombinant tissue plasminogen activator (rtPA) is a promising treatment, outcomes have not been compared in randomized trials.
