The diagnosis of pulmonary sequestration traditionally requires arteriography to identify abnormal systemic vessels feeding the abnormal portion of the lung. Non-invasive imaging techniques have recently been used to replace arteriography. Conventional computed tomographic (CT) scanning is, however, at a disadvantage because of its inability to obtain multiplanar images. The combination of slip ring CT scanning and computerised three-dimensional reconstruction (spiral CT angiography) can be used to visualise the anatomical detail of a wide range of vessels within the lung. Four cases of pulmonary sequestration are reported which were successfully diagnosed using spiral CT angiography. Spiral CT scanning allows simultaneous imaging of anomalous vessels and lung parenchyma in a single examination and is particularly useful in the diagnosis and assessment of pulmonary sequestration.
传统上，肺隔离症的诊断需要进行动脉造影，以识别为肺部异常部分供血的异常体循环血管。近年来，非侵入性成像技术已被用于取代动脉造影。然而，传统的计算机断层扫描（CT）由于无法获取多平面图像而存在劣势。滑环CT扫描与计算机三维重建（螺旋CT血管造影）相结合，可用于显示肺内各种血管的解剖细节。本文报告了4例使用螺旋CT血管造影成功诊断的肺隔离症病例。螺旋CT扫描能够在一次检查中同时对异常血管和肺实质进行成像，在肺隔离症的诊断和评估中特别有用。
