Digital cine angio system was developed a few years ago and is being using widely for cardiac examinations. However, the image quality of digital imaging in clinical examinations is seldom evaluated. We have attempted to evaluate the digital imaging in D.C.I. First, each segment of coronary arteries that is exposed in routine projection angle were visually evaluated. Second, regarding the appearance of the coronary arteries on the diaphragm we compared digital imaging with cine film. As a result, the image quality of the coronary arteries except for segments 7 to 10 (classified by A.H.A.) was evaluated as being good. Regarding the appearance of coronary arteries on a diaphragm, digital imaging was evaluated higher than cine film. In this report, the advantages of digital imaging in coronary angiography were studied.
