Eine Phantomstudie zur Strahlenexposition des Untersuchers bei Rotationsaquisitionen mit einer Flachdetektor-Angiographie-Anlage
(2014-07-21)In addition to the conventional digital subtraction angiography (DSA), rotation angiographies and DYNA-CTs have been implemented particularly since the introduction of angiographic systems using flat-panel detector technology. ... -
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 ... -
Endovaskulär interventionelles Notfallmanagement des akuten A. carotis-interna-Verschlusses
(2013-11-04)Untreated acute occlusion of the internal carotid artery (ICA) comes along with high morbidity and mortality. The incidence rate is about 6 per 100000 persons a year. While for treatment of ICA stenosis interventional stent ... -
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 ... -
