Effect of coronary stenosis severity on variability of quantitative arteriography, and implications for interventional trials.
Q uantitative coronary arteriography is now routinely used in studies assessing arterial remodelling in response to interventions such as lipid lowering and percutaneous transltinal coronary angioplasty. Although this methodology provides both relative and absolute measurements that can be evaluated statistically as continuous variables, it is, however, often desirable or necessary to establish...
متن کاملCORONARY ARTERY DISEASE Computerized image analysis for quantitative measurement of vessel diameter from cineangiograms
Subjective estimates of the angiographic severity of coronary artery stenoses show variability and inaccuracy. We therefore tested the accuracy of a newly developed computerized image analysis system for quantitating vessel diameter from cineangiograms. Fourteen cylindrical phantoms of known diameter were filled with contrast medium and filmed over a wide range of clinically relevant radiograph...

15 صفحه اولClinical Applications of Coronary Arteriography By RICHARD
A NEW diagnostic test such as coronary IAV arteriography must pass through three stages before its ultimate elinical applicability can be determined. During the first stage, the test is used by its developers on a limited group of patients. During the second stage, the test is applied widely as clinical investigators explore possible niew applications. Coronary arteriography is in this second s...
