P.056 Dual-energy CT for differentiating intracerebral hemorrhage from Contrast Extravasation after Acute Ischemic Stroke Intervention (DECT-ICH)

Evaluation of dual-energy CT for differentiating intracerebral hemorrhage from iodinated contrast material staining.

PURPOSE To evaluate the efficacy of dual-energy computed tomography (CT) in the differentiation of intracerebral hemorrhage (ICH) from iodinated contrast material in patients who received contrast material via intraarterial or intravenous delivery. MATERIALS AND METHODS This retrospective study was approved by the local institutional review board, which waived the informed consent requirement...

Diagnostic agreement of the baseline CT and dual-energy CT to differentiate the cerebral hemorrhage from contrast extravasation in patients with acute ischemic stroke after endovascular treatment

Contrast extravasation on CT predicts mortality in primary intracerebral hemorrhage.

BACKGROUND AND PURPOSE Recent studies of intracerebral hemorrhage (ICH) treatments have highlighted the need to identify reliable predictors of hematoma expansion. The goal of this study was to determine whether contrast extravasation on multisection CT angiography (CTA) and/or contrast-enhanced CT (CECT) of the brain is associated with hematoma expansion and increased mortality in patients wit...

Warfarin-associated intracerebral hemorrhage after ischemic stroke.

BACKGROUND AND PURPOSE The aim was to investigate the risk of intracerebral hemorrhage (ICH) in patients with ischemic stroke taking warfarin and whether this risk changed over time. METHODS Between 2001 and 2008, the Swedish Stroke Register registered 12,790 patients with ischemic stroke discharged on warfarin. The patients was studied in two 4-year periods (inclusion 2001-2004: follow-up un...

Imaging of contrast medium extravasation in anticoagulation-associated intracerebral hemorrhage with dual-energy computed tomography.

BACKGROUND AND PURPOSE Contrast medium extravasation (CE) in intracerebral hemorrhage (ICH) is a marker of ongoing bleeding and a predictor of hematoma expansion. The aims of the study were to establish an ICH model in which CE can be quantified, characterized in ICH during warfarin and dabigatran anticoagulation, and to evaluate effects of prothrombin complex concentrates on CE in warfarin-ass...
