16层螺旋CT在食管裂孔疝诊断中的应用

目的：探讨16层螺旋CT在食管裂孔疝诊断中的应用价值。方法：回顾25例经胃镜、手术或上消化道造影证实的食管裂孔疝患者的16层螺旋CT资料并加以分析。结果：16层螺旋CT可以清晰显示食管裂孔疝的疝囊大小、部位、形态、密度、膈肌裂孔情况及病变与邻近结构的关系。结论：16层螺旋CT通过薄层断面和多平面重建技术（MPR）可以多角度显示疝囊及内容物,可为肿瘤性病变及其他不明原因膈肌膨隆的鉴别诊断提供有价值的诊断信息。

Clinical application with 16-row spiral CT in diagnosis of esophageal hiatal hernia

Objective： To investigate diagnostic value of 16 slice spiral CT in esophageal hiata hernia. Methods： We reviewed 25 cases by gastroscope, operation or upper gastrointestina radiography confirmed esophageal hiatal hernia in patients with 16 slice spiral CT data, and analyzed. Results： Image of 16 slice spiral CT could clearly show the esophageal hiatal hernia hernia sac size, position, shape, density, the diaphragmatic hiatus and pathological relationship with adjacent structures. Conclusion： 16 slice spiral CT through thin section and multiplanar reconstruction （MPR） can be multi-angle display hernia sac and contents, especially in the display of the diaphragmatic hiatus of broadening and lesions and their relation to the adjacent tissues have irreplaceable role.At the same time and neoplastic lesions and other unexplained diaphragm bulge in the differential diagnosis of provide valuable diagnostic information.
