Abstract

Clinical medicine needs a convenient, relatively noninvasive technique for the measurement of regional arterial blood flow. Measurement of flow would be extremely useful in evaluating the improvement in flow following vascular surgery or angioplasty. A number of techniques based on film or video densitometry have been used.(3,4) More recently digital subtraction angiography has been used for the measurement of blood flow.(1,2,5) These techniques basically obtain the blood flow by measuring the time a bolus of contrast material takes to move between two points of an artery. By knowing the distance between the points, the average diameter of the vessel, and the bolus transit time the blood flow (cc/min) can be calculated.
