Purpose

The main complications of treatment of ischemic stroke is hemorrhagic transformation; large series have demonstrated its presence between 10-15% of strokes treated endovascularly, this results in a worse prognosis.

 

Sometimes, it is easy to recognize an intraparenchymal hematoma, but, considering the presence of contrast extravasation after intra-arterial recanalization occurs between 30-50% of cases, it can be a challenge differential diagnosis. In this situation Dual-energy CT takes an important role in patient management and prognosis.

 

Different studies have shown that the study with dual-energy CT is an excellent tool in differentiating between iodinated contrast and intracranial bleeding, finding high levels of sensitivity and specificity. However, to date has not been evaluated concordance of results between different observers according to their experience, as occur in clinical practice.

 

The purpose of this study was to determine the interobserver agreement of dual-energy CT and unenhanced CT between radiology resident and experimented neuroradiologists to detect and differentiate hemorrhage in patients with acute ischemic stroke after endovascular treatment.
