Non-contrast CT and CTA were performed using a multi-detector GE Revolition Evo 64 × 2 (General Electric Healthcare Chicago, USA). For non-contrast CT examination, images were acquired at 1 mm and 5 mm slice thickness. In CTA, 80-100 mL of nonionic contrast material was administered intravenously at a rate of 4.5 mL/sec with a Mallinckrodt automatic injector (Dublin, Ireland), and images with a slice thickness of 0.625 mm were obtained with the helical scanning technique. Maximum intensity projections (MIPs) images with a thickness of 5 mm were obtained in axial, coronal, and sagittal planes.
Automatic injector

Scanning and reconstruction protocol: All patients were scanned with 64-row multislice computed tomography system (Toshiba Aquilion 64; Toshiba Medical Systems; Japan). The imaging parameters were 120 kVp, 250 mA, 125 mAs with a collimation of 64 x 0.5 mm, and a rotation time of 0.5 seconds. Image reconstruction parameters were as follows: section thickness of 0.5 mm, overlapping steps of 0.3 mm, and field of view (FOV) of 120 mm 2 . After brain scanning without contrast administration, all patients were scanned with intravenous contrast application for enhancing intracranial vessels. An iodine contrast medium of 100 mL with a concentration of 300 mg Iodine per mL (Omnipaque® 300mg I/ml, Amersham health, Ireland) was used. Infusions were performed with an automatic injector system (Mallinckrodt automatic injector). The infusion rate was adjusted as 4 mL/sec. A bolus tracking method was used for synchronization of contrast medium and scanning time.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
