Abstract

We present here a user-friendly calculator for the setting of a pediatric split-bolus polytrauma computed tomography (CT) protocol with a mixed arterial and venous phase, aiming to both reduce radiation dose and improve workflow while assuring optimal image quality. All the different parameters are calculated based on patient's weight with rapid computation of the injected contrast media and saline volumes, injection's flow rate, injection's timing, and optimal acquisition time. The designed calculator is built in a widely available Google Sheets file, accessible by a quick response (QR) code. Although polytrauma imaging represents the main goal of the technique, it can be used in a wide variety of contexts, including oncological, infectious, and vascular pathologies.

摘要

我们在此呈现了一个用户友好型的计算器，用于制定儿科分割式双期 CT 方案（动脉期和静脉期），旨在降低辐射剂量和优化工作流程的同时，确保获得最佳的图像质量。所有不同的参数都是基于患者的体重计算的，快速计算出注射的造影剂和生理盐水的体积、注射的流速、注射的时间以及最佳采集时间。设计的计算器内置于一个广泛使用的 Google Sheets 文件中，可以通过快速响应 (QR) 码访问。尽管多发伤成像代表了该技术的主要目标，但它可以在多种情况下使用，包括肿瘤学、传染病和血管病理学。
