X线平片检查对犬胃内不同性质异物诊断价值的研究

Diagnostic values of normal X-ray technology on different foreign bodies in canine stomach

犬胃内异物是犬常见病、多发病,对其准确的诊断是兽医临床实施有效治疗的主要环节。文章利用X线机对犬胃内9种异物病例进行X线平片的拍摄观察,并对犬胃内大小、形状、密度不同的异物(如棉花团、木块、实心塑料球、骨头块、金属管等)的诊断效果进行了归类、比较和分析。结果显示,X线平片检查能够清晰、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的显像效果不明显,甚至观察不到胃内异物的存在;胃内中等密度的异物虽然能够通过X线显示,但其轮廓不十分清晰。

Foreign body in canine stomach is the common and frequently encountered disease in veterinary clinic.Precise diagnosis of this disease is the most important process for effective treatment.Nine different physical characteristic foreign bodies in canine stomach were checked with normal X-ray technology so as to evaluate their diagnostic values.The foreign bodies were different in size,shape and density（for example,cotton,wood block,solid plastic ball,bone and metal pipe）.The results indicated that radiograph could clearly show high-density foreign bodies with their shape,size,character and location,but couldn’t obviously show low-density and middle-density foreign bodies.
