A prospective study was performed comparing computed and conventional radiography for the detection and visibility of cardiovascular devices in intensive care unit patients. Computed images were obtained using a commercially available 2K x 2K, 12-bit storage phosphor plate system. Image sets from 50 patients were assessed independently by three observers. A significant difference between the types of image was found for the detection of mediastinal drainage tubes and prosthetic valves. Computed images allowed greater confidence in the identification of courses and tips of lines. This advantage was most marked with edge-enhanced computed images.
进行了一项前瞻性研究，比较计算机断层扫描和传统放射成像在重症监护病房患者心血管装置检测及显影方面的效果。使用市售的2K×2K、12位存储磷光板系统获取计算机断层扫描图像。50名患者的图像集由三名观察者独立评估。在纵隔引流管和人工瓣膜的检测方面，发现两种图像类型存在显著差异。计算机断层扫描图像能让人对导管的走行和尖端位置的识别更有信心。这种优势在边缘增强的计算机断层扫描图像上最为明显。
