CT and MR Angiography are non-invasive techniques used to evaluate the integrity of vessels in patients with strokes, tumors or dissections. CTA uses a dynamic IV injection of contrast with a real time aquisition of data of the neck or brain for optimal vascular reconstruction. CT is better a differentiating soft from hard plaques and is better in patients with heavy calcifications. MRA can be done with or without contrast administration, and does not need x ray exposure, but may be susceptible to certain metallic and flow artifacts.
