Imaging of the course of the corticospinal tract (CST) by diffusion tensor imaging (DTI) is useful for function-preserving tumour surgery. The integration of functional localizer data into tracking algorithms offers to establish a direct structure-function relationship in DTI data. However, alterations of MRI signals in and adjacent to brain tumours often(More)
Endovascular therapy of extracranial carotid artery aneurysms (ECAA) and extracranial carotid artery pseudoaneurysms (ECAP) has become a common first-line treatment [1]. Covered stents and self-expanding bare metal stents have provided encouraging results. During mid-term follow-up of C12 months, stent-graft patency rates of C90 % are observed with(More)
BACKGROUND DTI-based tractography is an increasingly important tool for planning brain surgery in patients suffering from brain tumours. However, there is an ongoing debate which tracking approaches yield the most valid results. Especially the use of functional localizer data such as navigated transcranial magnetic stimulation (nTMS) or functional magnetic(More)
BACKGROUND AND PURPOSE The Acclino is a laser-cut closed-cell microstent composed of nitinol. It was developed for stent-assisted coiling of wide-neck intracranial aneurysms. The key feature of the stent is its deployability via low-profile microcatheters with an inner diameter of 0.0165 inch, which are also suited for coil deployment. The objective of this(More)
Two recent randomized controlled trials (RCT) consistently showed superiority of aggressive medical treatment versus percutaneous transluminal angioplasty and stenting (PTAS) in patients with intracranial artery stenosis. Patients with symptomatic basilar stenosis have a higher long-term risk of recurrent stroke compared to patients with anterior(More)
BACKGROUND Oxyhemoglobin-sensitive sequences, namely T2*, can indirectly depict changes in oxygen extraction. Purpose of this study was to investigate the dynamics of T2* changes in ischemic tissue. NEW METHOD We investigated earliest temporo-spatial dynamics within ischemic tissue, measured with quantitative T2* imaging in the histologically defined(More)
