Diffusion and perfusion MRI findings with clinical correlation in patients with subarachnoid haemorrhage related vasospasm

Abstract

Background. Early radiological diagnosis of vasospasm as well as the detection of ischemic areas and the definition of cerebral perfusion changes may have an impact on the Current unfavorable results in patients with vasopasm. We investigated diffusion weighted (DW) and perfusion weighted (PW) magnetic resonance (MR) changes together with catheter angiography findings and tried to correlate radiological and clinical findings.
