An inexpensive, simplified flow model for use with digital subtraction angiographic (DSA)
equipment is described. System tests show that the model gives reproducible data with a …

A steady-state flow model was used to optimize methods of data analysis, to investigate
variables that affect the time-density curves, and to determine the accuracy of transit-flow …

Measurement of blood flow from Cine-angio-grams, using a technique that obtains contrast
medium mass values at multitudinous positions along individual vessels and from numerous …

Eighteen digital subtraction angiography (DSA) examinations were retrospectively
evaluated for factors that led to their erroneous interpretation. Overlapping vessels obscured …

[en] The general principles of digital techniques in quantitating absolute blood flow during
arteriography are described. Results are presented for a phantom constructed to correlate …

Abstract From May, 1982 to May, 1983, 300 consecutive patients were examined by
intravenous digital subtraction angiography (DSA) using the Philips DVI system, which had a …

Intravenous DSA provides a safe, accurate, and cost-effective means of examining the
extracranial and intracranial vasculature on an inpatient or outpatient basis. Intra-arterial …

An inexpensive digital subtraction angiography (DSA) apparatus that can perform live
subtraction, processed subtraction, and road mapping is described. The apparatus can be …

Sixty-nine patients with 91 separate abnormal findings were studied by both intra-arterial
digital subtraction arteriography (ADSA) and conventional film screen subtraction …

The technique of radiographic subtraction was first described in 1935 (Ziedses des Plantes,
1935), although the first English language paper on the subject did not appear until 27 years …
