This is a 3D reformatted image from a CTA (computed tomography angiography) of the aortic arch and neck. CT angiography is performed by scanning the patient while the injected IV contrast (dye) is in the arterial circulation. Helical images are obtained, which can subsequently be reformatted in any plane or in three-dimensions. This image is a three-dimensional volume rendered image.
