Blood flow rate and velocity are important parameters for the study of vasc
ular systems, and for the diagnosis, monitoring and evaluation of treatment
of cerebro- and cardiovascular disease. For rapid imaging of cerebral and
cardiac blood vessels, digital x-ray subtraction angiography has numerous a
dvantages over other modalities. Roentgen-videodensitometric techniques mea
sure blood flow and velocity from changes of contrast material density in x
-ray angiograms. Many roentgenvideodensitometric flow measurement methods c
an also be applied to CT, MR and rotational angiography images. Hence, roen
tgen-videodensitometric blood flow and velocity measurement from digital x-
ray angiograms represents an important research topic. This work contains a
critical review and bibliography surveying current and old developments in
the field. We present an extensive survey of English-language publications
on the subject and a classification of published algorithms. We also prese
nt descriptions and critical reviews of these algorithms. The algorithms ar
e reviewed with requirements imposed by neuro- and cardiovascular clinical
environments in mind. (C) 2000 American Association of Physicists in Medici
