Abstract

This chapter focuses on the imaging of hyperacute ischemic stroke patients within the first hours after stroke onset when the decisions to administer thrombolytics or perform thrombectomy are of paramount importance. The major goals of imaging during this hyperacute phase of ischemia include (1) the exclusion of intracerebral hemorrhage for thrombolysis, (2) the detection of acute ischemia in order to exclude stroke mimics, (3) emerging advanced imaging techniques to delineate ischemic but viable tissue for possible intervention beyond the current window, and (4) the imaging of pediatric acute stroke patients. The chapter provides an in-depth discussion of the literature supporting the use of specific modalities for each of the major goals listed.

Notes

Acknowledgments

The authors would like to acknowledge the work of Dr. Weili Lin, who was a co-author with them on two chapters on imaging of acute ischemic stroke, one in Evidence-Based Neuroimaging and Diagnosis: Improving the Quality of Neuroimaging in Patients and one in Evidence-Based Imaging: Improving the Quality of Imaging in Patients, both published by Springer Science (2013 and 2011, respectively) and both edited by LS Medina et al. This current chapter draws upon those chapters, in the process of presenting thoroughly updated and significantly revised coverage of this subject for emergency imaging.
