Diagnostic Values Of B-mode Ultrasound And Normal X-ray Technology On Different Foreign Bodies In Canine Stomach

Ten different physical characteristic foreign bodies in canine stomach were checked with B-mode ultrasound and normal X-ray technology so as to evaluate their diagnostic values. The foreign bodies were different in size, shape and density (for example, cotton, plastic bag, ping-pong, wood block, battery, solid plastic ball, bone, stone, glass plug 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. Ultrasonograph could show all of the different foreign bodies in canine stomach, but couldn't show their character. High-density foreign bodies greatly different from gastric tissue and the feed in stomach, could form lively acoustics interface. Low-density foreign bodies within much micro-air bubbles inside could form strong echograph.According to this research, the diagnostic values of B-mode ultrasound to low density foreign bodies (the cotton, the plastic bag) in canine stomach were better than normal X-ray's, but the diagnostic values of normal X-ray technology were better than ultrasound to high density foreign bodies in canine stomach.
