CT angiography (CTA) combines a CT scan with the injection of dye. CT stands for computed tomography. This technique is able to create pictures of the blood vessels in the neck.
Computerized tomography (CT) scanning is useful to get a very detailed 3D image of certain parts of the body. The process begins by taking many different X-ray views at various different angles, which are then combined with the use of computer processing to create cross-sectional images of the bones and soft tissue inside of your body, including tissues inside of solid organ. Ordinary X-ray testing does not show clear images of soft tissue, so doctors often request CT scanning to get a good image of soft tissue including organs, muscles, blood vessels, nerves and the brain. Sometimes a CONTRAST dye is used as it shows up clearer on the screen. During a quality CT scan of the cervical spine, a doctor will be able to see cross-sections of your neck and upper spine. The CT scan may also be called a neck CT scan.
