ABSTRACT

Objective:To evaluate the spiral CT in the diagnosis of esophageal neoplasm by comparing it with conventional CT and barium meal examination.Methods:Spiral CT contrast enhancement scanning and image processing with MPR an d CTVE were performed in 15 cases.A comparison was made between the images of spiral CT and the ones of conventional CT and the images of barium meal examinat ion.Results:① On axial images with spiral CT,all lesions of 15 patients showed almo s t the same pictures as seen with conventional CT.Images clearly showed the posit ion,size,shape of the esophageal neoplasm with local extension and the relation with the adjacent structures as well as lymth node metastases.②MPR could we ll display esophageal structure through different angle and direction.The appea rances of inner wall and lesions on CTVE of esophageal neoplasm were similar to those of fiberaptic endoscopy.③Barium meal examinatiuon was a very effective sc reening method.Conclusion:Compared with conventional CT and barium meal examination,application of spiral CT provides clinicians with more useful informations.
