.... Velthuis; on behalf of the Dutch acute stroke study (DUST) investigators Background: CT angiography (CTA) and CT perfusion (CTP) are important diagnostic tools in acute ischemic stroke. We investigated the prognostic value of CTA and CTP for clinical outcome and determined whether they have additional...

... can cause thromboembolic events but are often overlooked. They can elude standard identification by transesophageal echocardiography (TEE), which is invasive or at best uncomfortable for many patients. CT angiography (CTA) can be used as an alternative or in addition to TEE if this technique fails...

... of collateralization in the ischemic territory as a predictor of infarct size. Methods: Twenty-five patients (17 women, 8 men, mean age: 67.6 ± 12.4 years) selected by non-contrast-enhanced CT and CT angiography (CTA) underwent intra-arterial thrombolysis (iaT) within 6 h after symptom onset (mean 4.1 ± 1.3 h...

... characteristics in elucidating differential stroke outcomes between the sexes. Methods: We prospectively evaluated consecutive patients with acute ischemic stroke. CT angiography (CTA) was performed in all patients within 24 h of symptom onset. CTA source images were used to evaluate lesion volume. The primary...

... for Understanding Stroke Evolution (DEFUSE) trial. Patients with a malignant profile had a low chance for an independent functional outcome despite thrombolysis within 3–6 h. We sought to determine whether CT angiography (CTA) could identify a malignant imaging profile within 3 h from symptom onset. Methods: We...
