Imaging pediatric elbow trauma in the acute setting remains diagnostically challenging given difficult patient positioning, multiple ossification centers of the pediatric elbow, overlapping structures, and complex joint anatomy. Digital tomosynthesis is a technique where the X-ray source travels across a limited arc angle, obtaining a series of low-dose exposures that are in turn digitally reconstructed to produce high in-plane resolution at a relatively low overall radiation dose. Digital tomosynthesis is now more commonly integrated into standard radiographic machines and offers a new and exciting way to assess the pediatric elbow. In this review article we discuss the clinical applications of digital tomosynthesis in pediatric elbow trauma along with challenges related to technique, patient positioning and artifacts.

小儿肘的数字断层合成。

鉴于患者定位困难，小儿肘部骨化中心多，结构重叠以及关节解剖复杂，在急性情况下对小儿肘部创伤进行成像仍然在诊断上具有挑战性。数字断层合成是一种技术，其中X射线源在有限的弧角上传播，获得一系列低剂量的曝光，然后对这些低剂量的曝光进行数字重建，以在相对较低的总辐射剂量下产生较高的平面分辨率。现在，数字断层合成通常被集成到标准放射线照相设备中，并提供了一种新颖而激动人心的方式来评估小儿肘关节。在这篇综述文章中，我们讨论了数字断层合成在小儿肘部创伤中的临床应用以及与技术，患者定位和人工制品有关的挑战。
