作者采用了具有连续旋转能力的计算机断层扫描（CT）扫描仪的传输系统来检查单次屏气期间的完整肺亚容量。24名成年患者接受了最多12个连续1秒旋转的扫描，数据采集与患者纵向运动同步，每秒一个切片厚度。回顾性地从体积内的任何水平获得插值平面原始数据，这些数据提供了与标准图像相当的高质量图像。孤立性肺结节没有被遗漏，其中心总是可以被描绘出来，并且很容易获得二次重建和三维重建。作者认为，螺旋容积CT，通过完全测量肺的一个亚容积，是一种有吸引力的CT新应用。
The authors adapted the transport system of a computed tomographic (CT) scanner with continuous rotation capability to examine complete lung subvolumes during a single breath hold. Twenty-four adult patients underwent scanning with up to 12 continuous 1-second rotations, and data acquisition was synchronized with longitudinal patient motion at one section thickness per second. Interpolated planar raw data were obtained retrospectively from any level within the volume, and these afforded high-quality images that were comparable to standard images. Solitary pulmonary nodules were not omitted, their centers could always be depicted, and secondary reformations as well as three-dimensional reconstructions were obtained easily. The authors conclude that spiral volumetric CT, by completely surveying a subvolume of the lung, is an attractive new application of CT.
