Abstract

Contrast enhanced ultrasonography (CEUS) refers to the use of ultrasound contrast medium in conventional ultrasonography to enhance the visualisation of the region under study. A two year old male Labrador Retriever, weighing 27 kg was presented with a history of anorexia and intermittent vomiting since one week. Abdominal radiography showed a radiopaque foreign body within the intestine. Conventional ultrasonography could not provide proper intestinal lumen visibility due to gas artefacts. Contrast enhanced ultrasonography was done after giving polyethylene glycol (PEG) electrolyte solution via nasogastric intubation. Gas artefacts were reduced and the segmented dilated loops with accumulated contrast medium was visible. Dilated and normal loops could be identified sonographically. Exploratory laparotomy with enterectomy and enteroanastomosis was performed to correct the condition. The animal made an uneventful recovery. The surgical and sonographical findings were retrospectively compared.
