[CT angiography of the pulmonary artery in patients with bronchial carcinoma].
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.
