Implication

Prospective study reveals CT angiography matches catheter angiography in only 50% of carotid bifurcations, indicating it cannot reliably replace catheter-based imaging.

Key Points

To compare the diagnostic performance of CT angiography with conventional catheter angiography in evaluating common carotid artery bifurcation disease among symptomatic patients.
Prospective study of 10 symptomatic patients (20 common carotid artery bifurcations) evaluated with contrast-enhanced spiral CT of the neck.
CT data were preprocessed and postprocessed using volume-rendering techniques and maximum-intensity-projection algorithms before all patients underwent conventional catheter angiography.
CT angiographic findings matched conventional catheter angiograms in 50% of evaluated bifurcations (10 of 20).
CT angiography missed two nearly occluded internal carotid arteries and incorrectly identified four patent internal carotid arteries as fully occluded.
Only two of five severe stenoses identified on CT angiography were confirmed by catheter angiography.
