Summary
Utilizing digital subtraction angiography (DSA) is costly. However, using computed contrast-enhanced digital subtraction (CCDS) examinations significantly reduced angiographic costs by 177,000 DM annually.
Area of Science:
- Medical Imaging
- Radiology
- Cost-Effectiveness Analysis
Background:
- Digital subtraction angiography (DSA) is a common diagnostic tool.
- DSA procedures, particularly those involving intra-arterial contrast or shunt angiography, incur substantial costs.
Purpose of the Study:
- To compare the costs of computed contrast-enhanced digital subtraction (CCDS) examinations with traditional digital subtraction angiography (DSA).
- To evaluate the potential cost savings of implementing CCDS in clinical practice.
Main Methods:
- A retrospective study analyzed data from 2909 CCDS examinations and 1893 DSA examinations over two years.
- Cost per examination was calculated for both CCDS (147 DM) and DSA (709 DM).
Main Results:
- CCDS examinations were found to be significantly more cost-effective than DSA.
- The average cost per DSA examination was 709 DM, compared to 147 DM for CCDS.
- Implementation of CCDS led to an annual cost reduction of 177,000 DM for angiographic procedures.
Conclusions:
- CCDS offers a substantial cost-saving alternative to conventional DSA.
- Adopting CCDS can lead to significant financial benefits in diagnostic imaging departments.
- This study highlights the economic advantages of CCDS in reducing healthcare expenditure for angiographic examinations.
