(2017-06-13)The treatment of aneurysmal subarachnoid hemorrhage (aSAH) still is a major concerne in the field of neurological diseases. Despite improved diagnostics and therapies, the mortality and morbidity after aSAH remains at a ... -
Anwendbarkeit des Alberta Stroke Program Early CT Score (ASPECTS) anhand multimodaler CT-Bildgebung in der Schlaganfallfrühdiagnostik und dessen Fähigkeit zur Vorhersage des klinischen Behandlungsergebnisses für Patienten, welche durch Thrombusextraktion durch Aspiration behandelt werden.
(2016-12-14)Ischaemic stroke is a severe incident which requires quick vessel recanalisation. To achieve this, several therapeutic approaches exist. Quick image based patient selection for individual therapeutic decisions is crucial ... -
Meningeosis neoplastica: Der Einfluss von Tumorart und Liquorzellzahl auf die Diagnostik
(2016-07-26)Background. Although CSF cytology and MRI are standard methods to diagnose neoplastic meningitis (NM), this complication of neoplastic disease remains difficult to detect. We therefore reevaluated the sensitivity of ... -

(2015-03-04)Background: The aim of this study is to compare the longterm outcome of patients with microsurgical clipping and endovasculare coil embolization basis of objective and subjective parameters. Methods: Data from 161 patients ... -
Magnetresonanztomographie bei Patienten mit der E200K- und V210I-Mutation
(2014-10-10)Prion diseases are a group of rare infectious neurodegenerative disorders, which are caused by aggregation of the misfolded pathological prion protein. Three subtypes can be distinguished according to their etiology: ... -
Können cervicale Lymphknoten vorhersagen, ob eine Carotisplaque vulnerabel ist?
(2014-02-03)Introduction: In histological studies, patients with symptomatic carotid stenosis show characteristics of plaque vulnerability: a thin fibrous cap and a large lipid core. Inflammation is thought to contribute to rupture ... -
Halsgefäßstenosen Computertomographische Angiographie (CTA) versus Digitale Subtraktionsangiographie (DSA)
(2013-08-27)The stroke ranks among the most common lethal diseases in Germany. Approximately 20% of the insults are caused by occlusion or embolic effective material of plaque ruptures of constricted cervical vessels. An early diagnosis ... -
Anwendbarkeit der angiographischen CT in der periinterventionellen Bildgebung
(2013-07-02)BACKGROUND AND PURPOSE: The ability to perform neuroimaging on the angiography suite is important in making decisions during neurointerventions. Our aim was the evaluation of ACT as a fast available diagnostic tool during ... -
