The Digital Imaging and Communications in Medicine (DICOM) standard is the universal format for interoperability in medical imaging. In addition to imaging data, DICOM has evolved to support a wide range of imaging metadata including contrast administration data that is readily available from many modern contrast injectors. Contrast agent, route of administration, start and stop time, volume, flow rate, and duration can be recorded using DICOM attributes [1]. While this information is sparsely and inconsistently recorded in routine clinical practice, it could potentially be of significant diagnostic value. This work will describe parameters recorded by automatic contrast injectors, summarize the DICOM mechanisms available for tracking contrast injection data, and discuss the role of such data in clinical radiology.
医学数字成像和通信（DICOM）标准是医学成像中实现互操作性的通用格式。除了成像数据外，DICOM已经发展到支持广泛的成像元数据，包括可从许多现代造影剂注射器轻松获取的造影剂给药数据。造影剂、给药途径、开始和停止时间、体积、流速和持续时间可以使用DICOM属性进行记录[1]。虽然这些信息在常规临床实践中记录稀少且不一致，但它可能具有重要的诊断价值。这项工作将描述自动造影剂注射器记录的参数，总结可用于跟踪造影剂注射数据的DICOM机制，并讨论此类数据在临床放射学中的作用。
