The Cost effectiveness of digital subtraction angiography in the diagnosis of cerebrovascular disease

Book excerpt: In the case study, a single category of clinical problems where digi- tal subtraction angiography (Dsa) Is in use on a broad scale, cere- brovascular diseases, is selected as the context within which the cost effectiveness of dsa is explored. The intention of the study is to present a careful description of the current and potential appli- cation of dsa within the area of diagnostic radiology concerned with cerebrovascular disease and to suggest the implication of the techno- logy for patterns of clinical practice and patient care costs under different assumptions.
