| ［摘要］ 目的 探讨优化重组技术在冠心病患者心率过快和心率波动中的诊断价值。方法 选取196例确诊为冠心病的患者，据心率程度及波动范围分为四组，均行64层螺旋CT检查，以优化重组技术评估各组各支冠脉可评价率。结果 四组自动重组后各支血管图像质量比较差异均有统计学意义（P<0.01）,A组优于其他三组（P<0.01）；再次优化重组后各支血管图像质量比较，左回旋支及右冠状动脉差异有统计学意义（P<0.01）；自动重组和再次优化重组后，B、C、D组各支可评价率比较差异均有统计学意义（P<0.05或P<0.01）。结论 64层螺旋CT优化重组技术可有效提高影像图像可评价率，但仍存在一定的局限和不足，检查前有效控制心率及心率波动可提高可评价率和诊断率。 |

| Abstract: |
| ［Abstract］ Objective To study the diagnostic value of restructuring optimization technology in coronary heart disease(CHD) patients with high heart rate and heart rate fluctuations.Methods According to the degree of heart rate and the range,196 CHD patients were divided into 4 groups and examined by 64-slice CT.According to restructuring optimization technology,the valuable rate of each coronary artery between groups were compared.Results After automatic restructuring,there were statistically significant difference in the evascular image quality between 4 groups(P<0.01), the image quality of group A was better than that of the other 3 groups(P<0.01); After again restructuring, the vascular image quality of left circumflex branch and right coronary artery between 4 groups were significant difference(P<0.01). After again restructuring optimization and automatic, the evaluable rates between groups B, C, D were statistically significant difference(P<0.05 or P<0.01).Conclusion 64-slice CT restructuring optimization technology can effectively increase the evaluable rate of video image, but there are still certain limitation and the insufficiency, and the effective control of heart rate and heart rate fluctuations before examination can improve the evaluable rate and the diagnostic rate. |
