Asymptomatic versus Symptomatic Infarcts from Vasospasm in Patients with Subarachnoid Hemorrhage: Serial Magnetic Resonance Imaging

Abstract

Analysis of the data confirmed the occurrence of asymptomatic infarcts due to vasospasm. These infarcts often developed in noneloquent areas representing perforator territory. MRI investigation of vasospastic lesions referable to intraparenchymal vessels such as perforators complements the study of extraparenchymal major vessel vasospasm in patients with SAH by computed tomographic angiography.
