Stroke is a major health burden worldwide with attendant mortality, morbidity, and cost. In 2010, there were approximately 16.9 million strokes and an estimated 33 million stroke survivors worldwide. ⋯ The staggering economic cost of the disease is driven largely by disability and long term care. Efforts in stroke healthcare delivery are focusing on performance, efficiency and value to better serve the consumer.

ReviewAcute Neurologic Syndromes Beyond Stroke: The Role of Emergent MR Imaging.
MR imaging with diffusion-weighted imaging has been essential in the evaluation of acute stroke but is also crucial for the diagnosis, treatment, and follow-up in patients with various nonischemic disorders, including infectious processes, trauma, toxic/metabolic disorders, and other abnormalities. This article reviews various disorders with diffusion abnormality that can be commonly seen in the emergency setting.

ReviewThe Adult Patient with Acute Neurologic Deficit: An Update on Imaging Trends.
Stroke is the clinical syndrome of abrupt onset of acute neurologic deficit owing to decreased oxygen delivery to the brain, resulting in ischemia or infarction. Approximately 87% of strokes are ischemic and 13% are hemorrhagic. Improved awareness of the neuroimaging findings highlighted in recent stroke clinical trials, as well as of their role in patient selection for novel treatment options-including "late window" (8-24 hours post-ictus!) intraarterial thrombectomy-has become increasingly important. This article focuses on the role of neuroimaging in the assessment and management of patients with acute ischemic stroke.
