Imaging in Acute Ischemic Stroke

Opening of the article

With recent advances in imaging and efficacious treatment of cerebral ischemia, the role of imaging and neuroradiologist has become central from peripheral. CT scan can be done as an initial imaging of clinically suspected patient of stroke mainly to rule out hemorrhage and stroke mimickers like mass lesion. CT angioplasty and perfusion imaging can be performed to look for major vessel occlusion and tissue at risk. MR imaging is better imaging modality to diagnose acute ischemic stroke with use of diffusion weighted imging. Perfusion and diffusion mismatch are very much suggestive of salvgeable brain parenchyma.
