BACKGROUND AND PURPOSE Both the existence and clinical relevance of a steal phenomenon in brain arteriovenous malformations (AVMs) remains a matter of debate. This study aimed to assess perfusion in the brain adjacent to brain AVMs and to relate these to macrovascular blood flow in a single measurement. MATERIALS AND METHODS Twenty consecutive patients(More)
In this paper methods for visualization and analysis of cerebral arteriovenous malformations (AVM) are presented. Spatiotemporal 4D magnetic resonance angiography (MRA) image datasets and 3D MRA datasets with high spatial resolution were acquired for analyzing AVMs. One of the main tasks is the combination of the information of these 3D and 4D MRA image(More)
• TA: Time To Appearance (Zeit bis zum An-stieg) und • MSM: Maximum Slope Model (Zeit bis zum maximalen Anstieg) betrachtet [2]. Diese Parameter führten bei den vorliegenden 4D-Treat-Bildfolgen teilweise zu starken Artefakten in Form von zeitlichen Differenzen zwischen den Ein-flusszeitpunkten zweier benachbarter Voxel. Ziel dieser Arbeit ist es, eine(More)
