[Improvement of specificity in evaluation of aortocoronary bypass grafts by serial (dynamic) computed tomography (author's transl)].
Serial (dynamic) Computed Tomography (CT) with a non-periodic reconstruction of 21 images per minute improves specificity in evaluation of aortocoronary bypass grafts. In 35 bypass grafts, selective coronary arteriography was performed the day after CT: Sensitivity of CT-technique was 92%, specificity 89%. Without additional serial Ct, sensitivity was 85%, specificity 67%. Quantitative CT-measurements of flow equivalents showed no significant differences within two groups with angiographically displayed different "run off".
