Spiral CT scanning is a non-invasive imaging modality that produces a three-dimensional reconstruction of the axial images and allows for evaluation of the cervical and intracranial vasculature after rapid contrast administration. One of its advantages is the ability to make a distinction between high-grade stenosis and total vessel occlusion, based on slight differences in contrast. Large ulcerations can be demonstrated, although calcification is still a source of error. Advantages of spiral CT angiography include its easy accessibility and tolerability by anxious patients and those with a large body habitus, who would have difficulty fitting in an MRI scanner. Disadvantages include exposure to ionizing radiation, allergic reactions to contrast material and potential nephrotoxicity.
