Digital subtraction angiography — Wikipedia Republished. CT angiography (CTA) Being one of the leading tertiary hospitals in Singapore, different CT scanners with individual characteristics were utilised to cater to the high patient volume. Siemens CT angiography versus Digital Subtraction angiography for intracranial vascular pathology in a clinical setting Yang Cunli, Li Ser Khoo, Puay Joo Lim, Eng, 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.
