The feasibility of using computed tomography (CT) to identify the common bile duct (CBD) and comparison with ultrasonography (US) results were evaluated in normal beagle dogs and dogs without hepatobiliary and pancreatic diseases. In addition, CBD diameters were obtained from CT at the level of the porta hepatis and the duodenal papilla level in dogs with underlying diseases that may cause cholestasis. US is a useful modality in the estimation of gallbladder volume because ejection fraction and CBD diameter from US were not significantly different from those of CT. The normal biliary tract was visible on CT images in 68% of the normal dog group. CBD diameter was not over 3 mm and 3.5 mm at the porta hepatis and duodenal papilla levels, respectively in normal dogs weighing less than 15 kg. Dogs suspected to have cholestasis associated with hepatobiliary or pancreatic diseases had significantly larger CBD than that in normal dogs.
在正常比格犬以及无肝胆和胰腺疾病的犬只中，评估了使用计算机断层扫描（CT）识别胆总管（CBD）的可行性，并与超声检查（US）结果进行比较。此外，在可能导致胆汁淤积的潜在疾病犬只中，从肝门水平和十二指肠乳头水平的CT图像上获取了CBD直径。超声检查在估计胆囊容积方面是一种有用的方法，因为超声检查得出的射血分数和CBD直径与CT检查结果无显著差异。正常犬组中，68%的犬在CT图像上可见正常胆道。体重小于15 kg的正常犬，肝门水平和十二指肠乳头水平的CBD直径分别不超过3 mm和3.5 mm。疑似患有与肝胆或胰腺疾病相关胆汁淤积的犬只，其CBD明显大于正常犬。
