MR Imaging of the Brain 1 Year after Aneurysmal Subarachnoid Hemorrhage: Randomized Study Comparing Surgical with Endovascular Treatment

Abstract

Parenchymal high-SI lesions on T2- and intermediate-weighted MR images are more frequent after early surgical rather than endovascular treatment of the ruptured aneurysm, and lesion volumes correlate with the neuropsychologic test performance.
