A four year study has been undertaken into the effects on the workload and cost implications of the introduction of digital subtraction angiography (DSA) in a large United Kingdom teaching hospital. The increase in workload has been entirely due to the ability to perform intravenous angiography. DSA is cheaper than conventional angiography if more than 210 cases are undertaken each year. This difference is accounted for by the reduced use of X-ray film. However, intravenous angiography is more expensive because of the use of large volumes of nonionic medium.
在英国一家大型教学医院开展了一项为期四年的研究，旨在探讨引入数字减影血管造影（DSA）对工作量和成本的影响。工作量的增加完全归因于进行静脉血管造影的能力。如果每年进行超过210例手术，DSA比传统血管造影更便宜。这种差异是由于X射线胶片使用量减少所致。然而，由于使用大量非离子型造影剂，静脉血管造影成本更高。
