CT angiography

Last edited and medically reviewed by on

CT angiography, also abbreviated as CTA, is vascular imaging by CT after contrast administration.

Procedure

Optimal results of intracranial CT angiography are achieved in patients who are able to hold their breath for 30-40 seconds to undergo an artifact-free spiral CT[^1]. In contrast to digital subtraction angiography, the resolution is lower, particularly for vessels that run perpendicular to the axial CT plane[^1].
