Computed Tomographic Angiography of the Cervical Neurovasculature

ByFelix E Diehn, Paul Lindell

Computed tomographic angiography (CTA) is a non-inva-

sive tool for the evaluation of the cervical and cerebral vas-

culature. The development and application of this

technique has occurred later than the competing modalities

of digital subtraction angiography (DSA) and magnetic res-

onance angiography (MRA). While CTA is the relative

newcomer, recent advances in CT technology have made it

progressively more competitive with these other modalities.

The current use of CTA, MRA and DSA in the evaluation

of the cervical and cerebral vasculature is in flux, and is
