Modern Neuroimaging Techniques in Diagnosing Transient Ischemic Attack and Acute Ischemic Stroke

Neuroimaging should be obtained for all patients suspected of having acute ischemic stroke or transient ischemic attack. Noncontrast head computed tomography (CT) scans are used to exclude hemorrhage, evaluate for early brain injury, and exclude stroke mimics. CT angiography assists in identifying proximal vessel occlusions, dissection, or high-grade arterial stenoses. Additional imaging techniques have emerged to improve selection of patients likely to benefit from therapies. Artificial intelligence applications assist in acute stroke imaging assessment, identifying acute hemorrhage, and predicting risk of endovascular intervention in acute large vessel occlusion.
