Abstract
- 3D DSA has been introduced recently and was known to be useful for evaluating aneurysmal shapes and relations to neighboring arteries. However, there are some problems related to image acquisition and reconstruction of 3D DSA, such as artifacts. We present two cases showing perforators to arise from the aneurysmal dome on 3D DSA, which is probably associated with artifacts.
