Rapid advances are changing the technology and applications of multidetector computed tomography (CT) scanners. The major increase in data associated with this new technology, however, breaks most commercial picture archiving and communication system (PACS) architectures by preventing them from delivering data in real time to radiologists and outside clinicians. We proposed a phased model for 3D workflow, installed a thin-slice archive and measured thin-slice data storage over a period of 5 months. A mean of 1,869 CT studies were stored per month, with an average of 643 images per study and a mean total volume of 588 GB/month. We also surveyed 48 radiologists to determine diagnostic use, impressions of thin-slice value, and requirements for retention times. The majority of radiologists thought thin slice was helpful for diagnosis and regularly used the application. Permanent storage of thin slice CT is likely to become best practice and a mission-critical pursuit for the health care enterprise.
快速发展正在改变多探测器计算机断层扫描（CT）扫描仪的技术和应用。然而，与这项新技术相关的数据大幅增加，打破了大多数商业图像存档与通信系统（PACS）的架构，使它们无法将数据实时传送给放射科医生和外部临床医生。我们提出了一个用于三维工作流程的分阶段模型，安装了一个薄层存档，并在5个月的时间里测量了薄层数据存储情况。每月平均存储1869例CT研究，每项研究平均有643幅图像，每月平均总体积为588GB。我们还对48名放射科医生进行了调查，以确定诊断用途、对薄层价值的看法以及保留时间的要求。大多数放射科医生认为薄层有助于诊断并经常使用该应用程序。薄层CT的永久存储可能会成为医疗企业的最佳实践和关键任务追求。
