Methods A hybrid approach based on established processes described by Glaser15 and by
the National Institutes of Health (http://prevention. nih. gov/cdp/about. aspx) 16 was used to …

Computed tomographic (CT) pulmonary angiography is becoming the standard of care at
many institutions for the evaluation of patients with suspected pulmonary embolism. This …

Background CT perfusion (CTP) and diffusion or perfusion MRI might assist patient selection
for endovascular thrombectomy. We aimed to establish whether imaging assessments of …

Background In patients with acute ischemic stroke caused by a proximal intracranial arterial
occlusion, intraarterial treatment is highly effective for emergency revascularization …

Background The effect of endovascular thrombectomy that is performed more than 6 hours
after the onset of ischemic stroke is uncertain. Patients with a clinical deficit that is …

Background Whether brain imaging can identify patients who are most likely to benefit from
therapies for acute ischemic stroke and whether endovascular thrombectomy improves …

Background The effectiveness of endovascular therapy in patients with stroke caused by
basilar-artery occlusion has not been well studied. Methods We randomly assigned patients …

Background and Purpose—In acute ischemic stroke, fast and complete recanalization of the
occluded vessel is associated with improved outcomes. We describe a novel measure for …

Background and Purpose—The role of noninvasive methods in the evaluation of collateral
circulation has yet to be defined. We hypothesized that a favorable pattern of …

Importance Endovascular therapy (EVT) is the standard of care for select patients who had a
stroke caused by a large vessel occlusion in the anterior circulation, but there is uncertainty …
