Waleed Brinjikji, Timo Krings: Imaging in Neurovascular Disease. A Case-Based Approach

Excerpt

Neurovascular imaging has been completely revolutionized in the last decades because of a sequence of new acquisitions started from a time when interventional angiography was alone as a diagnostic and therapeutic option. The advent of computerized imaging created a differentiation between different procedures, with a diagnostic role for invasive angiography remained in conditions in which both approaches have to be associated. At present, without the need of an intra-arterial injection, it is possible to acquire very effective angiographic information with ultrasounds (US), computed tomography (CT), and magnetic resonance (MR). Of particular relevance is the contribution allowed by MR, also because of the possibility to add a pathophysiological information, achievable through functional MR (fMRI), to morphostructural and angiographic data. …
