[Retrospective analysis of routine-MRI and correlation with aetiology of dementia, severity and neuropsychology in a memory-clinic population].

Background: The contribution of potential treatable dementia aetiologies diagnosed using cerebral imaging varied considerably in previous studies and was not evaluated in a recent larger German sample of patients from a memory clinic.

Material And Methods: MRI images of 502 patients were retrospectively reassessed. Beside the proportion of potentially treatable dementia aetiology, the extent of whole brain atrophy (semiquantitative) and vascular white matter lesions were assessed.

Multimodality approach in cryptogenic epilepsy with focus on morphometric 3T MRI.

Purpose: This study aimed to investigate the potential contribution of morphometric MRI analysis in comparison to other modalities, such as MEG, SPECT and PET, in identifying the epileptogenic focus in patients with cryptogenic epilepsy.

Patients And Methods: Study inclusion was limited to epilepsy patients with a monolobar focus hypothesis, as concluded from EEG/seizure semiology and the best individual concordance rate. Feature maps, generated by the MATLAB(®) "morphometric analysis program" (MAP), were evaluated by a neuroradiologist blinded to conventional MRI and the focus hypothesis (MAP(1)).

Intravenous flat detector CT angiography for non-invasive visualisation of intracranial flow diverter: technical feasibility.

Objective: To demonstrate the feasibility of intravenous Flat Detector CT Angiography (FD-CTA) for visualisation of intracranial Flow Diverting Devices. Flow Diverting Devices are used increasingly for treatment of intracranial aneurysms. A close follow up is necessary because it becomes obvious that a significant proportion of aneurysms treated with these devices remain patent.

Monofocal MEG in lesional TLE: does video EEG monitoring add crucial information?

Objective: Unilateral monofocal temporal magnetoencephalography (MEG) findings might determine epileptogenicity of a lesion in symptomatic epilepsy during presurgical evaluation. To evaluate the additive effect of video-electroencephalography (vEEG), monofocal temporal lobe MEG findings were compared to electrophysiological findings from vEEGs of patients with lesional epilepsy.

Methods: In 28 patients with drug-resistant lesional temporal lobe epilepsy (TLE), epileptogenicity of the lesion was determined by monofocal temporal MEG localisations.

Optimized intravenous Flat Detector CT for non-invasive visualization of intracranial stents: first results.

Objective: As stents for treating intracranial atherosclerotic stenosis may develop in-stent re-stenosis (ISR) in up to 30%, follow-up imaging is mandatory. Residual stenosis (RS) is not rare. We evaluated an optimised Flat Detector CT protocol with intravenous contrast material application (i.
