犬胃内异物X光射线诊断的研究

Study on Canine Gastric Foreign Bodies by X-ray Diagnosis

在已有病例的基础上通过鉴别对比,分析各种胃内异物X光片的特点,为临床诊断提供依据。利用X光机对犬胃内异物病例进行X光平片的拍摄观察,并对犬胃内大小、形状、密度不同的异物的诊断效果进行了归类、比较和分析。结果显示:X光平片检查能够清晰、直观地显示胃内高密度异物,并且能够对其准确地定位;但对于胃内低密度异物几乎不成像,甚至观察不到胃内异物的存在。但是使用造影剂后,就可以使低密度异物成像;胃内中等密度的异物虽然能够通过X光显示,但其轮廓不十分清晰。结果表明:对于中高密度的胃内异物,X光平片检查效果明显好于低密度的胃内异物,而低密度异物借助造影剂后能够较准确地定位。

Through comparison and identification of existing cases, features of various gastric foreign bodies in X-ray radiographs was analyzed to provide the foundation for clinical diagnosis. X-ray radiographs of gastric foreign bodies cases were taken,classified, compared and analyzed by observing X-ray diagnostic effect on gastric foreign body of different size,shape and density. Results showed that the X-ray radiographs could clearly and visually display gastric foreign body of high density and accurately fix the position of gastric foreign body,but gastric foreign bodies with low density couldn＇t be imaged nearly in X-ray radiograph. The foreign bodies with low density might be imaged in X-ray radiographs by using contrast agent. Although foreign bodies with medium density could show X-ray films,and its outline wasn＇t very clear. Conclusions obtained that gastric foreign bodies of high and medium density in X-ray radiographs was significantly better than that in low density,and low density foreign bodies after using contrast agents could accurately fix.
