对儿科先天性心脏病 (CHD) 患者进行心血管计算机断层扫描 (CT) 通常具有挑战性。这可能是由于患者合作有限、心率较高、疾病的复杂性和多样性以及放射剂量最小化的需要。随着第三代双源 (DS) 双能 (DE) CT 扫描仪的推出，CT 技术的最新发展非常适合应对这些挑战。 DSCT的特点是音调高、解剖覆盖范围长、心电图同步扫描更加灵活。 DE 提供有关血管结构、心肌和肺灌注的附加临床信息，并可减少伪影。这些进步增加了儿童先心病患者的临床适应症并修改了 CT 方案。在我院，采用 DE 技术的 DSCT 已迅速成为儿科先心病患者术前和术后管理的重要影像技术。本文的目的是描述儿科 CHD 患者采用 DE 技术的最新 DSCT 方案，并提供我们在 18 个月期间的经验的一些案例。
Cardiovascular computer tomography (CT) in pediatric congenital heart disease (CHD) patients is often challenging. This might be due to limited patient cooperation, the high heart rate, the complexity and variety of diseases and the need for radiation dose minimization. The recent developments in CT technology with the introduction of the third-generation dual-source (DS) dual-energy (DE) CT scanners well suited to respond to these challenges. DSCT is characterized by high-pitch, long anatomic coverage and a more flexible electrocardiogram-synchronized scan. DE provides additional clinical information about vascular structures, myocardial and lung perfusion and allows artifacts reduction. These advances have increased clinical indications and modified CT protocol for pediatric CHD patients. In our hospital, DSCT with DE technology has rapidly become an important imaging technique for both pre- and postoperative management of pediatric patients with CHDs. The aim of this article is to describe the state-of-the-art in DSCT protocol with DE technology in pediatric CHD patients, providing some case examples of our experience over an 18-month period.
