Twinkling Artifact on Intracerebral Color Doppler Sonography
a From the Division of Diagnostic and Interventional Radiology, Geneva University Hospital, 1211 Geneva 14, Switzerland.
Summary: Transcranial Doppler sonography shows potential as a noninvasive technique for long-term follow-up of treated intracranial saccular aneurysms. This technical note describes a color Doppler artifact related to microcoil architecture that might represent a potential pitfall in transcranial Doppler sonographic evaluation of aneurysmal cavity thrombosis, since it may be wrongly interpreted as residual flow or aneurysmal cavity recanalization.
