[Coronary flow measurements, using cine densitometry. Results using a multiple detector method. I. Normal flow values in healthy and stenosed coronary arteries during rest (author's transl)].

Coronary blood flow was measured by a cine densitometric method using a newly developed system incorporating computer data analysis. The first results concerning front and wave velocity of a selectively injected contrast bolus are reported. Average absolute flow volumes in the right coronary artery are 114 ml. per minute, in the left coronary artery, 88 ml per minute (RIVA = 52 ml/min., RC = ml/min.). There is good agreement with the results of dye dilution and isotope wash out techniques, but the latter are more complicated and less easily reproduced and therefore less suitable for routine use. The results are critically evaluated.
