Clinical Application of Low Tube Voltage Combined with Iterative Reconstruction in Lower Extremity Arterial CTA
-
摘要: 目的：探讨80kV管电压结合迭代重建技术在下肢动脉CT血管成像中的应用价值。方法：将40例拟行下肢CTA检查的患者随机分为两组，实验组扫描及注射参数为80kVp，对照组为100kVp。对比两组辐射剂量、对比剂剂量和图像质量。结果：对照组的有效辐射剂量和对比剂剂量（95mL）明显高于实验组，差异具有统计学意义（P<0.001）；两组血管强化CT值和图像质量主观评分均无统计学差异（P均大于0.05）。结论：80kV管电压结合迭代重建技术的CT扫描技术应用于下肢动脉CTA成像，在保证图像质量的前提下能显著降低辐射剂量和对比剂剂量，具有重要应用推广价值。Abstract: Objective:To explore the application value of 80kV tube voltage combined with iterative reconstruction technology in CT angiography of lower extremity artery. Methods:40 patients were randomly divided into two groups. The parameters of scanning and injection were 80kV in the experimental group and 100kV in the control group. The radiation dose, contrast dose and image quality were compared between the two groups. Results:The effective radiation dose and contrast dose (95mL) of the control group were significantly higher than those of the experimental group, the difference was statistically significant (P<0.001); there was no statistical difference between the two groups in the CT value of vascular enhancement and the subjective score of image quality (P>0.05). Conclusion:The CT scanning technology of 80kV tube voltage combined with iterative reconstruction technology can significantly reduce the radiation dose and contrast agent dose on the premise of ensuring the image quality, which has important application and promotion value.
