Abstract
Clinical 16 mm cinefluorography and 70 mm camera fluorography were compared in 30
unselected patients undergoing coronary arteriography. Accuracy in detecting coronary
arterial stenosis and collateral vessels and in assessing the degree of stenosis was
similar with the two techniques. With both methods, there were significant inter-
and intraobserver differences in estimating the degree of stenosis. These differences
indicate that coronary arteriography is only a semiquantitative method for making
decisions about treatment, prognosis and follow-up of patients. The use of more than
one observer increases the likelihood that stenotic lesions will be detected. Interobserver
variation in detecting collateral circulation is small.
