双源CT Flash Spiral模式在非镇静状态下婴幼儿胸部CT检查中的应用
摘要
目的:对于非镇静状态下婴幼儿胸部CT检查中应用双源CTFlashSpiral模式的具体方法以及应用价值施行分析。方法:选取我们医院所接诊的胸部疾病婴幼儿病人资料100例施行分析,所选100例婴幼儿病人中50例接受双源CTFlashSpiral模式进行扫描,扫描期间病人处于清醒状态,剩余50例婴幼儿病人接受64层CT常规螺距模式加以扫描,扫描期间病人处在睡眠状态,比较两组图像质量、辐射剂量和扫描时间。结果:两组婴幼儿病人检查所得图像质量、辐射剂量以及扫描时间对比差异明显。结论:临床中对于非镇静状态下婴幼儿胸部CT检查中开展双源CT Flash Spiral模式效果理想,扫描速度比较快,所产生的辐射剂量比较低,应该给予大力的推广与应用。
