  • Title: Intra-arterial digital subtraction angiography.
    Author: Foley WD, Milde MW.
    Journal: Radiol Clin North Am; 1985 Jun; 23(2):293-319. PubMed ID: 2986195.
    Abstract:
    DSA is an imaging technique that should be integrated into a state-of-the-art angiographic system for proper application and utilization. This results in improvements in both efficiency and diagnostic accuracy. However, from the physician's viewpoint, the proper use of a DSA imaging facility mandates not only an understanding of angiographic principles as applied with conventional film-screen systems but also an in-depth understanding of the factors that affect DSA performance. In particular, factors affecting spatial resolution and contrast sensitivity are crucial. This knowledge has to be applied interactively and "on-line" to achieve optimal IA-DSA image quality.
