Computerized Tomography Angiography

Although not currently used in routine clinical practice, computerized tomography angiography (CTA) can resolve aneurysms as small as 2-3 mm, with sensitivities of 77-97% and specificities of 87-100% [11]. The use of helical CT scanners has dramatically reduced imaging times, as well as patient movement artefact allowing acquisition of the entire CT volume in 30-45 s during first arterial pass of an intravenous contrast injection. Although helpful in demonstrating aneurysms, reformats can be difficult and time-consuming.

The most compelling indication for CTA is in the unstable patient requiring craniotomy for aneurysmal ICH before a cerebral angiogram can be performed, although there may be difficulties in visualizing small perforators. There may be a role for CTA in the follow-up of surgical remnants, unruptured aneurysms and partially coiled lesions.
