Extent of hypoattenuation on CT angiography source images predicts functional outcome in patients with basilar artery occlusion.
BACKGROUND AND PURPOSE Quantification of early ischemic changes (EIC) may predict functional outcome in patients with basilar artery occlusion (BAO). We tested the validity of a novel CT score, the posterior circulation Acute Stroke Prognosis Early CT score (pc-ASPECTS). METHODS Pc-ASPECTS allots the posterior circulation 10 points. Two points each are subtracted for EIC in midbrain or pons a...
متن کاملExtent of hypoattenuation on CT angiography source images in basilar artery occlusion: prognostic value in the Basilar Artery International Cooperation Study.
BACKGROUND AND PURPOSE The posterior circulation Acute Stroke Prognosis Early CT Score (pc-ASPECTS) quantifies the extent of early ischemic changes in the posterior circulation with a 10-point grading system. We hypothesized that pc-ASPECTS applied to CT angiography source images predicts functional outcome of patients in the Basilar Artery International Cooperation Study (BASICS). METHODS BA...
متن کاملCT angiography source images predict final infarct extent in patients with basilar artery occlusion.
BACKGROUND AND PURPOSE The posterior circulation Acute Stroke Prognosis Early CT Score (pc-ASPECTS) is a 10-point grading system to quantify ischemic changes in the posterior circulation. We analyzed whether pc-ASPECTS on CT angiography (CTA) source images (CTASI) predicted the final infarct extent and hemorrhagic transformation (HT) rate in patients with basilar artery occlusion. MATERIALS A...
متن کاملCT diagnosis of basilar artery occlusion.
Basilar artery occlusion was diagnosed by high-resolution computed tomography (CT) in 11 cases. The normal basilar artery imaged on plain CT scans has an attenuation value not higher than that of whole blood. If the CT attenuation value of the vessel is higher than that of blood, basilar artery occlusion is probably present. The tentative diagnosis can be confirmed by comparison of the attenuat...
متن کاملThe Basilar Artery on Computed Tomography Angiography Prognostic Score for Basilar Artery Occlusion.
BACKGROUND AND PURPOSE Basilar artery occlusion is associated with high risk of disability and mortality. This study aimed to assess the prognostic value of a new radiological score: the Basilar Artery on Computed Tomography Angiography (BATMAN) score. METHODS A retrospective analysis of consecutive stroke patients with basilar artery occlusion diagnosed on computed tomographic angiography wa...
