摘要: Abstract Purpose Cone beam CT (CBCT) imaging assessment of acute ischemic stroke (AIS) patients with large-vessel occlusion (LVO) in the angiosuite may improve workflow and decrease time to recanalization. In order for this gain widespread acceptance, current CBCT needs further development image quality. Our study aimed compare quality a new protocol performed directly from multidetector as gold standard. Methods AIS an LVO who were candidates endovascular treatment prospectively included study. Following conventional (MDCT), underwent unenhanced cone (XperCT, Philips) angiosuite, using two different protocols: standard 20.8 s XperCT and/or improved 10.4 s protocol. Images evaluated both qualitative quantitative methods. Results We 65 Patients received prior treatment; 18 assessed scans 47 newer scan. The analysis showed that mean contrast-to-noise ratio (CNR) was significantly higher compared (2.08 +/- 0.64 vs. 1.15 0.27, p  Conclusions Continued advances cone-beam allow marked improvements brain parenchyma, which supports direct-to-angiosuite approach eligible thrombectomy treatment.
