| 目的：探究第二代双源CT 自适应前瞻性心电触发序列扫描冠脉成像临床价值及应用前景。方法：将2012 年10 月至2014
年10 月期间因持续房颤等心血管疾病入院接受治疗的120 例患者纳入本次研究，随机分为研究组（60 例）和对照组（60 例），研
究组患者采用第二代双源CT自适应前瞻性心电触发序列扫描冠脉成像进行检查，对照组患者则采用回顾性心电门控螺旋扫描。
对比两组辐射剂量，图像质量评分及图像有效诊断率。结果：研究组患者Z-轴扫描范围、容积CT 剂量指数（CTDIvol）、平均有效
剂量(ED)、平均剂量长度乘积(DLP)均明显低于对照组，比较差异均具有统计学意义(P<0.05)。研究组图像质量评分及图像有效诊
断率均明显优于对照组，差异均有显著统计学意义(P<0.05)。结论：第二代双源CT 前瞻性心电触发序列扫描，具有有效诊断率高，
辐射量低，安全性较好的优点，在冠脉成像中具有较高的推广应用价值。 |

| Objective:To explore the application value of second generation of dual source CT adaptive prospectively
electrocardiography triggering sequence scanning in coronary angiography.Methods:A total of 120 patients with persistent atrial
fibrillation and other cardiovascular diseases, who were treated in Beijing Shijitan Affiliated Hospital of Capital Medical University from
October 2012 to October 2014, were randomly divided into research group (n=60) and control group (n=60). The research group was
detected by second generation of dual source CT adaptive prospectively electrocardiography triggering sequence scanning in coronary
angiography, while the control group, by retrospective electrocardiography gated spiral scanning.Then the radiation dose, image quality
score and effective diagnostic rate in the two groups were compared.Results:The Z-axial scanning range, volume CT dose index
(CTDIvol), effective dose(ED), dose-length product(DLP) in the research group were significantly lower than those in the control group,
the differences were significantly different (P<0.05). And the image quality score and effective diagnostic rate in the research group were
significantly better than those in the control group, the differences were significantly different(P<0.05).Conclusion:Second generation of
dual source CT adaptive prospectively electrocardiography triggering sequence scanning has the advantages of highly effective diagnostic
rate, low radiation dose, and good safety, which is widely applied to coronary angiography. |
