Abstract

In the last 20 years, CT evolved from single-slice scanning towards multidetector-row CT (MDCT). Technical advances in MDCT have increasingly improved spatial and temporal resolution. Fast volume coverage within a few seconds has nowadays become possible, allowing vessel imaging of the whole body. CT angiography (CTA) has become a valuable noninvasive alternative to cerebral digital subtraction angiography (DSA) for diagnosing pathology of intracranial vessels.Because acquired MDCT data are nowadays nearly isotropic, various image post-processing techniques can be applied. For detection of intracranial aneurysms, CTA has largely replaced DSA as the first-line imaging modality.New applications like dynamic CTA and dual-energy CT (DECT) are emerging and are more and more used in daily practice.This chapter aims to give an update on state-of-the-art CT imaging of intracranial vessels. The anatomy of the intracranial vessels and some anatomical variations are described first. This is followed by technical aspects of CT imaging of the intracranial vessels. Finally, indications and protocols for imaging of the intracranial arteries and vein vessels are described.
