The aim of the study was to evaluate 3D computed tomography (3D-CT) for the visualization of tumor extent with respect to the infiltration of the pulmonary arteries in patients with locally advanced small and nonsmall-cell lung cancer. A total 61 examinations in 40 patients with bronchial carcinoma were performed with contrast-enhanced (150 ml injected with 4 ml/s after bolus tracking) 2 mm spiral CT (pitch 1.5, increment 1 mm) (Somatom Plus4, Siemens AG, Germany). Using the implemented software cine mode, surface shaded display (SSD), and maximum intensity projection (MIP), reconstructions of the pulmonary arteries and the tumors were generated. In comparison to conventional spiral thoracic CT, the optimized cross-sectional images of the mediastium represented a benefit with the technique described, and this can help to diagnose vessel infiltration and may therefore be of value for pre- and post-therapeutic staging in modern stage-adapted multimodality treatment programs.
本研究的目的是评估三维计算机断层扫描（3D-CT）在局部晚期小细胞肺癌和非小细胞肺癌患者中对肿瘤侵犯肺动脉范围的可视化情况。对40例支气管癌患者共进行了61次检查，采用对比增强（团注追踪后以4ml/s的速度注入150ml）2mm螺旋CT（螺距1.5，层厚1mm）（德国西门子公司Somatom Plus4）。使用已安装的软件电影模式、表面阴影显示（SSD）和最大密度投影（MIP），生成肺动脉和肿瘤的重建图像。与传统螺旋胸部CT相比，所描述的技术能提供优化的纵隔横断面图像，有助于诊断血管侵犯，因此在现代适应分期的多模式治疗方案中对治疗前和治疗后的分期可能具有价值。
