64排螺旋CT及其后处理技术在老年人食管异物诊断中的价值

Clinical application of 64 slice-spiral CT with post-processing techniques in diagnosis of oldman esophagus foreign body

目的:探讨64排螺旋CT及其后处理技术在老年人食管异物诊断中的临床应用价值。方法:收集本院临床拟诊断食管异物的老年患者(≥60岁)39例,均采用64排螺旋CT行常规扫描及三维重建,其中1例加增强扫描,总结分析其CT表现,并将CT诊断结果与手术或胃镜检查结果作对照。结果:在39例患者中,CT诊断食管异物34例,CT表现为食管内高密度影,食管壁增厚,食管脓肿,食管穿孔,食管梗阻。64排螺旋CT及其后处理技术诊断老年人食管异物的敏感度为97.05%,特异度为80.00%,准确率为87.18%。结论:64排螺旋CT及其后处理技术对老年人食管异物有较高的诊断价值,可作为首选检查方法。

Objective：To explore the clinical application of 64-slice spiral CT with post-processing techniques in diagnosis of oldman esophagus foreign body.Method：39aged（greater than or equal to 60years）patients with clinically suspected of esophagus foreign body were enrolled in this study.All cases were examined with routine CT scanning and three-dimensional reconstruction,of them,1patient underwent contrast-enhanced CT scan.CT findings were retrospecttively analyzed and compared with that of surgery or gastroscopy.Result：Of 39 patients,esophagus foreign body was diagnosed by CT in 34 cases.CT signs of oldman esophagus foreign body include high density in esophugas,esophugas inflammation,esophugas perrforation,esophugas abscess,esophugas obstructure.In diagnosing oldman esophagus foreign body,the sensitivity,specificity,rate of accuracy were 97.05%,80.00%,87.18%.Conclusion：64-slice spiral CT with post-processing techniques has the high value in the diagnosis of oldman esophugas foreign bodies,which should be used as the first examination method fo rthis disease.
