Amnesia After Surgery for Anterior Communicating Aneurysm： High Resolution Magnetic Resonance (MR) Imaging Findings

To clarify whether amnesia after treatment of anterior communicating aneurysm (ACoA)is related to infarcts caused by occlusion or damage of the perforating artery of the ACoA, we used 3.0-T 3D high resolution MR imaging to identify and localize infarcts in patients with amnesia following treatment of ACoA aneurysm.
