CT neuroangiography: a glance at the common pitfalls and their prevention.
OBJECTIVE
The author's objective was to address several pitfalls and missteps of CT angiography (CTA) with pictorial examples and ways to overcome potential misinterpretations. CTA is increasingly used for the noninvasive evaluation of the carotid and intracranial vessels. Ease of data acquisition may belie the complexity of interpreting each individual vessel and understanding myriad postprocessing techniques, each with its strengths and weaknesses.


CONCLUSIONS
Diagnostic yield and accuracy of CT angiography are enhanced by good data acquisition and by understanding and fully exploiting postprocessing techniques.
