A Perforator Originating from the Aneurysmal Dome : Image Artifact of 3D Digital Subtraction Angiogram / 신경중재치료의학

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.
