Neurologische Notfälle in der Mehrschichtcomputertomographie

Neurologic emergencies and multislice computed tomography

Zusammenfassung

Die moderne Mehrschichtcomputertomographie (MSCT) ist aufgrund ihrer breiten Verfügbarkeit und kurzen Untersuchungszeiten das bevorzugte Primärdiagnostikum bei neurologischen Notfällen und hat durch ihre stetige Weiterentwicklung in den letzten Jahren an Bedeutung gewonnen. Durch die immer höher werdende Ortsauflösung und die Entwicklung neuer Datenbearbeitungsverfahren verdrängt die nichtinvasive MSCT-Angiographie die diagnostische DSA zunehmend und ist eine geeignete Methode für die Evaluation von intrakraniellen Aneurysmen, Karotisstenosen, arteriellen Dissektionen sowie Sinus-, Hirnvenen- und Basilaristhrombosen. Die multimodale CT (native CCT, CTA und Perfusions-CT) wird bei Schlaganfallpatienten immer öfter eingesetzt. Sie erhöht die Detektionsrate früher Ischämien und wird voraussichtlich die Therapie des akuten Schlaganfalls verbessern.

Abstract

Modern MSCT with its broad availability and rapid examination times is the preferred modality in the initial evaluation of neurologic emergencies and by its continual development has become more important within recent years. With increased spatial resolution and new post-processing techniques, non-invasive MSCT angiography is seen to increasingly replace diagnostic DSA. Multidetector CTA is a suitable method for the evaluation of intracranial aneurysms, carotid artery stenoses, arterial dissections, as well as cerebral venous and basilar artery thromboses. Multimodal CT (non-enhanced CCT, CTA and perfusion CT) is used more frequently in the assessment of acute stroke patients, it increases the detection rate of early ischemia and is likely to improve the treatment of acute stroke.
