| 摘 要： | 目的：对比分析两种不同方向的肺部螺旋CT扫描的图像质量。方法：随机选择100例肺部扫描的患者,者人头→足和足→头两种方向扫描，两组图像按有无呼吸运动伪影，对比剂伪影来评定质量。结果：两组图像质量存在明显的差异。结论：肺部螺旋CT扫描时，采用由足→头方向扫描，能够获得更好的满足诊断要求的CT图像。

| Abstract: | Objective:To evaluate the image quality of lung spiral CT scanning in two different directions.Methods:100 patients selected randomly were performed lung spiral CT scanning at head first and vice versa foot first.The image quality in two different scanning directions was compared when breathing motion artifacts and contrast media artifacts were assessed.Results:The difference of image quality between two groups was significant.Conclusion:Compared with CT scanning at head first,the image quality at foot first is much better in meeting the requirement of the diagnosis. |
