Evolution of Embolic Agents in Interventional NeuroradiologySpringer Science and Business Media LLC - Tập 25 - Trang 333-339 - 2015
F. Brassel, D. Meila
The growth in understanding of the pathophysiological relationships between various neurovascular diseases in the past decades has increased the significance and need for endovascular treatment. Consequently, an extraordinary development of different embolic agents was indispensable. The present work first presents the historical milestones in the discovery of various embolic materials used for ne...... hiện toàn bộ

To evaluate diagnostic image quality of ultra-high-resolution computed tomography angiography (UHR-CTA) in neurovascular imaging as compared to normal resolution CT-angiography (NR-CTA). In this retrospective single-center study brain and neck CT-angiography was performed using an ultra-high-resolution computed tomography scanner (n = 82) or a normal resolution CT scanner (NR-CTA; n = 73). Ultra-h...... hiện toàn bộ
Desired Qualities of Endovascular Tools and Barriers to Treating Medium Vessel Occlusion MeVOSpringer Science and Business Media LLC - Tập 33 - Trang 155-160 - 2022

Endovascular treatment (EVT) for stroke due to medium vessel occlusion (MeVO) can be technically challenging and specific endovascular tools are needed to safely and effectively recanalize these relatively small and fragile vessels. We aimed to gain insight into availability and desired qualities of endovascular devices used in MeVO stroke and examined barriers to adoption of MeVO EVT in clinical ...... hiện toàn bộ
Funktionelle Inaktivierung des Hippokampus im intrakarotidalen Wada-TestSpringer Science and Business Media LLC - Tập 8 - Trang 182-185 - 1998

In einer prospektiven Studie untersuchten wir die Amobarbitalverteilung im Hippokampus während des intrakarotidalen Wada-Tests. Hierzu wurden 200 mg Amobarbital zusammen mit 37 MBq Tc-99m-HMPAO selektiv in die Arteria carotis interna bei 45 Hemisphären von 27 Patienten injiziert. Im anschließend angefertigten hochauflösenden Einzelphotonen-Emissionstomogramm (SPECT) war der Hippokampus abgrenzbar....... hiện toàn bộ

The aim of this study was to investigate an imaging biomarker based on contrast enhanced T1-weighted and T2-weighted magnetic resonance imaging (MRI) to determine the hearing loss related to acoustic neuromas (AN). In this retrospective study, 441 acoustic neuromas treated with microsurgery were included. The diagnostic and follow-up MRI and audiometry of these patients were compared. We discovere...... hiện toàn bộ
Three-Dimensional Visualization of Motor Cortex and Pyramidal Tracts Employing Functional and Diffusion Weighted MRI Methods, Applications and LimitationsSpringer Science and Business Media LLC - Tập 11 - Trang 105-121 - 2001

Background: Functional MRI (fMRI) combines anatomic with functional information and has, therefore, been widely used for preoperative planning of patients with mass lesions affecting functionally important brain regions. However, the course of functionally important fiber tracts is not visualized. We therefore propose to combine fMRI with diffusion weighted MRI (DWI) tha...... hiện toàn bộ
