Ultrasonography and radiography were used as an adjunct to clinical examination in the evaluation of 73 obstructed teats in 63 dairy cows. The images obtained with a 3.5 MHz and a 5 MHz linear array transducer were compared with radiographs and correlated with findings obtained at surgery. Ultrasonography and radiography allowed a correct assessment of the lesions in 68 respectively 58 teats. In five cases the obstructive lesions in the teat canal were not clearly discernible when ultrasonography was used. Radiography was the method of choice for the evaluation of the teat canal and small mucosal folds in the milk cistern. Ultrasonography was the method of choice for the detection of obstructive lesions at the base of the teat; all 14 of these cases were assessed correctly using ultrasonography versus three of 14 when radiography was used. Ultrasonography is a useful tool for the practitioner to evaluate obstructive teat lesions.
超声检查和X线摄影被用作临床检查的辅助手段，用于评估63头奶牛的73个阻塞乳头。将使用3.5MHz和5MHz线性阵列换能器获得的图像与X线片进行比较，并与手术结果相关联。超声检查和X线摄影分别在68个和58个乳头中对病变进行了正确评估。在5例中，使用超声检查时乳头管内的阻塞性病变无法清晰辨别。X线摄影是评估乳头管和乳池内小黏膜皱襞的首选方法。超声检查是检测乳头基部阻塞性病变的首选方法；在这些病例中，使用超声检查对所有14例均评估正确，而使用X线摄影时14例中仅3例评估正确。超声检查是从业者评估阻塞性乳头病变的有用工具。
