Angiographic Reconstruction Postprocessing Is Key to CTA
Published on Thu Feb 02, 2012
Need to distinguish CTA from CT? Computed tomographic angiography (CTA) is a non-invasive technique for imaging vessels, states CPT® Assistant (January 2007). The key distinction between CTA and computed tomography (CT) is that CTA includes reconstruction postprocessing of angiographic images and interpretation. If reconstruction postprocessing is not done, it is not a CTA study.
