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".
每分钟进行21幅图像的非周期性重建的连续(动态)计算机断层扫描(CT)可提高对主动脉冠状动脉搭桥术评估的特异性。在35例搭桥术中,CT检查后第二天进行了选择性冠状动脉造影:CT技术的敏感性为92%,特异性为89%。不进行额外的连续CT检查时,敏感性为85%,特异性为67%。两组血管造影显示不同“血流”情况下,CT对血流当量的定量测量无显著差异。
