CT-angiografi (CTA) med intravenös kontrast ger en snabb och god överblick över extra-och intrakraniella artärer. Påvisande av en extrakraniell eller intrakraniell ocklusion kan påverka valet av behandling (intravenös jämfört med intraarteriell trombolys eller trombektomi), även om mer forskning behövs innan tydliga slutsatser om urval av patienter till olika reperfusionsstrategier.

CT Protocols and Contrast Timing • CTA (CT Angiogram) - is a study of vascular structures and is an arterial study, therefore the timing will be consistent with arterial blood flow. For example if we are interested in imaging the carotid structures in the neck, our timing would generally be between 18 - 22 seconds from the introduction of the contrast media CT contrast agents, sometimes referred to as dyes, are used to highlight specific areas so that the organs, blood vessels, or tissues are more visible. By increasing the visibility of all surfaces of the organ or tissue being studied, they can help the radiologist determine the presence and extent of disease or injury

Images were reconstructed as linearly-blended 120-kV series (M_0.6) and with the standard. According to Conn's Current Therapy 2010, acute tubular necrosis can result due to the effects of computed tomography, or CT, contrast material.
