Historically, the evaluation of renovascular hypertension has been accomplished by US, renal scintigraphy and digital subtraction angiography. Based on its high accuracy reported in adults renal CT angiography (CTA) with pediatric-appropriate low radiation dose techniques has become an important tool in the workup of renovascular hypertension in children. Renal CTA has several advantages over more conventional imaging modalities, including rapid and non-invasive acquisition, high resolution and easy reproducibility. Additionally, in our experience high-quality renal CTA can be performed using low-dose radiation exposures and can be acquired without sedation in most instances. This article illustrates by examples the usefulness of renal CTA for diagnosis of childhood renovascular hypertension and provides an overview of renal CTA findings in the most common childhood renovascular diseases.
从历史上看，肾血管性高血压的评估是通过 US、肾闪烁显像和数字减影血管造影来完成的。基于其在成人中报道的高准确性，儿科适用的低辐射剂量技术的肾 CT 血管造影（CTA）已成为儿童肾血管性高血压检查中的重要工具。肾 CTA 与更传统的成像方式相比具有多个优势，包括快速、非侵入性采集、高分辨率和易于再现。此外，根据我们的经验，在大多数情况下，使用低剂量辐射可以进行高质量的肾 CTA，并且可以在不镇静的情况下进行采集。本文通过实例说明了肾 CTA 在儿童肾血管性高血压诊断中的有用性，并概述了最常见的儿童肾血管疾病的肾 CTA 表现。
