Recent advances in Computed Tomography (CT) have greatly increased the clinical applications of CT, especially since the advent of Multi-Detectors Row CT (MDCT) technology. CT Angiography (CTA) has been advocated for pre-operative evaluation of cerebral blood vessels pathologies and their relationship with the main branches. Moreover, it is crucial to detect other vascular morbidities, such as arterial occlusive diseases. CTA allows the proper visualization of main vascular structures and has several advantages: minimal invasiveness, with a lower complication rate than that of angiography; generation of high spatial resolution images; availability of multi planar reconstructions and 3D reconstructions; and short examination time, allowing extended scan ranges. Consequently, potenti... view more»
