Congenital lung anomalies vary widely in their clinical manifestation and imaging appearance. Although radiographs play a role in the incidental detection and initial imaging evaluation in patients with clinical suspicion of congenital lung anomalies, cross-sectional imaging such as computer tomography (CT) is frequently required for confirmation of diagnosis, further characterization, and preoperative evaluation in the case of surgical lesions. Recently, with the development and widespread availability of multidetector CT scanners, CT has assumed a greater role in the noninvasive evaluation of congenital lung anomalies. The combination of fast speed, high spatial resolution, and enhanced quality of multiplanar reformation and three-dimensional reconstructions makes multidetector CT an ideal noninvasive method for evaluating congenital lung anomalies. In this article, the authors review the multidetector CT technique for evaluation of congenital lung anomalies. Important clinical aspects, characteristic imaging features, and key points that allow differentiation among various anomalies are highlighted for a variety of common and uncommon conditions.
先天性肺发育异常的临床表现和影像学表现差异很大。虽然胸部X线片在偶然发现以及对临床怀疑有先天性肺发育异常的患者进行初步影像学评估中发挥作用，但对于确诊、进一步特征描述以及外科病变的术前评估，通常需要计算机断层扫描（CT）等横断面成像。近年来，随着多排CT扫描仪的发展和广泛应用，CT在先天性肺发育异常的无创评估中发挥了更大作用。多排CT速度快、空间分辨率高，多平面重组和三维重建质量提高，使其成为评估先天性肺发育异常的理想无创方法。在本文中，作者回顾了多排CT评估先天性肺发育异常的技术。针对各种常见和罕见情况，重点介绍了重要的临床方面、特征性影像学表现以及区分各种发育异常的关键点。
