摘要

目的:探讨螺旋CT低剂量扫描及图像后处理技术在食道异物中的诊断价值。方法:30例临床怀疑有食道异物患者

用3组不同的管电流（40、120、200 mA）行螺旋CT胸部扫描。进行VR等后处理技术重建

由2名放射科医师分析3组图像的质量、异物显示情况、食道异物检出情况

将结果进行统计学分析。结果:各组可符合临床诊断要求的后处理图像差异无统计学意义。40、120、200 mA扫描诊断的准确性都为100%。结论:低剂量扫描及后处理技术可明确诊断食道异物

并可作为电子内窥镜检前的筛查确定手术路径。螺旋CT低剂量扫描技术不影响图像后处理效果

可清楚显示病变

适用于食道异物患者的检查。

Abstract

Objective:To explore the diagnosis value of low-dose spiral CT scanning and image post-processing technology in the esophageal foreign body.Methods:A total of 30 cases with suspected esophageal foreign body

underwent spiral CT chest scan with 3 different sets of tube current(40

120

200 mA).And VR post-processing techniques were used for reconstruction

Image quality

foreign body shown and the esophageal foreign body detection of three groups were statistically analyzed by two radiologists.Results:The difference of groups meeting the requirements of the clinical diagnosis of post-treatment images was not statistically significant.Diagnostic accuracies of 40 120 and 200 mA scan were all 100%.Conclusion:Low-dose scanning and post-processing technology can accurately diagnose esophageal foreign body

and determine the path of surgery the screening before as an electronic endoscopies.Low-dose spiral CT scanning technology does not affect the image post-processing effects

and can clearly demonstrate lesions

which makes it applicable to the esophageal foreign body inspection.
