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

AI EXPLANATION: A computed tomographic angiography (CTA) of the upper extremity is an imaging test that examines the blood vessels in the shoulder, arm, forearm, wrist, or hand. An imaging technician injects a special contrast dye into a vein, which flows through the arteries and veins to highlight them clearly on a CT scanner. The machine captures multiple cross-sectional X-ray pictures, which computer software then combines into detailed two- and three-dimensional views of blood flow and vascular structures.
