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.
