CT Angiography Head Neck with Contrast

It is an imaging technique that uses a rotating beam of X-rays to create highly detailed 3-dimensional images of the blood vessels in the head and neck. The scan helps identify weakened sections of arteries or veins and to visualize blood flow. Your doctor may advise this scan to find out the cause of stroke, fainting, dizziness, difficulty pronouncing words, headache, and for planning brain tumour surgery.
