Neck CT Angiogram- Benefits and Risks

Neck CT angiogram is a convenient and noninvasive way of evaluating the blood vessels and tissues in the neck.
Neck CT angiography can detect narrowing or obstruction of blood vessels allowing for potentially corrective therapy to be done.
Many patients can undergo a neck CT angiogram instead of a conventional catheter angiography.
No radiation remains in a patient’s body after a neck CT angiogram.
X-rays used in neck CT angiogram should not have immediate side effects.

There is always a slight chance of cancer from excessive exposure to radiation. However, the benefit of an accurate diagnosis will generally outweigh the risk.
The effective radiation dose for this procedure varies.
Women should always inform their radiologist or technologist if there is any possibility that they are pregnant.
Neck CT angiogram is, in general, not recommended for pregnant women unless medically necessary because of potential risk to the baby.
The risk of serious allergic reaction to contrast materials can occur, but is extremely rare.
