New magnetic resonance imaging and computed tomography techniques for imaging of acute stroke

With continued advances in acute stroke therapy, the ability to accurately assess the physiologic status of ischemic brain tissue and related vascular lesions has become increasingly important. In this review, evidence regarding the use of new magnetic resonance imaging and computed tomography techniques to guide thrombolytic therapy, diagnose stroke subtype, and detect acute hemorrhage are discussed in order to provide a clearer picture of the status of these neuroimaging techniques in the assessment of acute ischemic stroke patients.
