January 2007 page 31-end Coding Communication: Radiology Question What is the difference between CT and CTA? AMA Comment Computed tomographic angiography (CTA) is a non-invasive technique for imaging vessels. The information obtained from the CTA is used in the evaluation of vascular anatomy (eg, renal or liver transplant donors, congenital anomalies), vascular disorders (eg, aortic or intracranial aneurysms, renal artery or carotid stenosis), and vascular trauma (eg, aortic laceration) and in the follow-up of organ transplantation. The key distinction between CTA and computed tomography (CT) is that CTA includes reconstruction postprocessing of angiographic images and interpretation. If reconstruction postprocessing...

Article Overview
This radiology coding article addresses a common question about computed tomography versus computed tomographic angiography and explains the broader context for imaging code reporting. It is aimed at coders and billing professionals who work with diagnostic radiology, vascular imaging, and contrast-related reporting. The article also references related guidance involving CT angiography, MR angiography, nuclear medicine, CT colonography, and cardiac CT/coronary CTA, helping readers understand the scope of the coding discussion without replacing the full premium text.
Why This Topic Matters
Accurate imaging code reporting depends on understanding which elements are included in a study and which related services are separately reportable. This article helps readers identify whether the topic applies to vascular imaging workflows and contrast-related coding questions.
