  • Title: [Effect of signal-to-noise ratio and window width on image information in transvenous DSA of different vascular regions].
    Author: Arlart IP, Ertel R.
    Journal: Rofo; 1986 Jun; 144(6):716-22. PubMed ID: 3012709.
    Abstract:
    The diagnostic quality of DSA images depends on numerous factors related to the apparatus and the technique of examination. An improvement in image can be brought about by correct choice of the mask and injected frames, by subsequent correct manipulation of the images and by the choice of the signal-to-noise ratio and window width. In the present study, the effect of these factors was demonstrated on image quality of venous DSA studies in various vascular regions. Practical advice is given for the examination of particular regions and for various diagnostic problems.
