Computed tomographic angiography, neck, with contrast material(s), including noncontrast images, if performed, and image postprocessing

AI EXPLANATION: A CT angiogram of the neck is an advanced imaging scan that evaluates the blood vessels carrying blood to the head and brain. During the procedure, a computed tomography scanner takes cross-sectional X-ray images while a contrast dye is administered into a vein. The contrast material highlights the carotid and vertebral arteries on the resulting pictures, enabling doctors to see blood flow and check for narrowing, blockages, aneurysms, or other vascular conditions.
