我们应用螺旋CT检查腹部和胸部。连续进行扫描，同时以恒定速度移动CT扫描仪的床面。当床面速度为20 mm/s时，可在单次屏气期间扫描整个肺野。检测到小至3 mm的肿瘤。螺旋CT的诊断检出率和准确性均远优于常规胸片，且具有上级诊断价值。在腹部检查期间，可以在注射造影剂期间的任何指定相位（优选动脉）扫描靶器官。我们发现了非常小的肝脏肿瘤，这是传统CT无法发现的。螺旋CT产生连续数据，重建以显示三维图像。螺旋CT可用于早期肺癌的普查和计算机辅助诊断。
We applied helical CT to examinations of the abdomen and thorax. Scanning was performed continuously while the couchtop of the CT scanner was shifted at a constant speed. The entire lung field could be scanned during a single holding of the breath when the couchtop speed was 20 mm/s. Tumors as small as 3 mm were detected. The diagnostic detectability and accuracy of helical CT were far superior to those of conventional chest radiography. During abdominal examination, the target organ could be scanned at any specified phase (preferably arterial) during the injection of contrast medium. We detected very small hepatic tumors which could not be detected by conventional CT. Helical CT produced continuous data, which was reconstructed to display three-dimensional images. Helical CT could be used in mass screening for the detection of early lung cancer and in computer-aided diagnosis.
