  • Title: [Quantitative flow measurement of the carotid artery using a combination of intra-arterial digital subtraction angiography and ultrasound].
    Author: Fiedler V, Sümpelmann R, Peters PE.
    Journal: Rofo; 1985 Dec; 143(6):655-60. PubMed ID: 3001856.
    Abstract:
    Arterial blood flow was estimated using digital subtraction roentgen-densitometry in a model of the cervical arteries. The best results were obtained with two sampling windows calculating the mean passage time using the line of gravity of the contrast bolus. Mechanical contrast injection created a systematic error by acceleration. This procedure was then used for examining five patients. Quantitative blood flow measurements required knowledge of the transverse vessel area. This was determined by high resolution sonography. Blood flow was calculated as the product of cross-sectional area and mainstream velocity.
