Axial NCCT examinations were obtained with 5-mm slice thickness reconstruction. CTA was performed as part of standard clinical care by scanning from the base of the skull base to the vertex using an axial technique, 0.5 section pitch, 1.25-mm collimation, kVp 120 – 140. Prior publications of an overlapping cohort described that CTA scans at our institution were typically acquired at either 235 or 350 mA14 (link),15 (link). On detailed review we found that a wide range of mA (80 to 630) was used in clinical practice. Intravenous iodinated contrast material (65 to 85 mL), was administered by power injector with an infusion rate of 4-5 mL/s with Smart-Prep, a semiautomatic contrast bolus triggering technique. The contrast materials used were IsoVue 370 and IsoVue 300 (iopamidal, Bracco Diagnostics Inc, Milan, Italy). Volumetric Computed Tomography Dose Index (CTDI-vol) ranged from 34.7 to 89.4 mGy (mean 60.9, SD 16.6) and Dose-Length Product (DLP) ranged from 628.7 to 3763.4 mGy–cm (mean 1923.6, SD 957.5).

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.
