B型超声诊断壶腹部肿瘤系统报道较少,定位准确率报道不一。本文分析了经手术及病理证实的75例壶腹部肿瘤超声图像特征。结果:B型超声在壶腹部肿瘤定位诊断中的准确性与检查者操作手法及经验密切相关。本文认为B超对壶腹部肿瘤的定位诊断准确率是较高的,达86％,不失为一种有价值的诊断手段。
B-type ultrasound diagnosis of ampulla tumor system is less reported, the accuracy rate of the report is not the same. This article analyzed the features of ultrasound images of 75 ampulla tumors confirmed by surgery and pathology. RESULTS: The accuracy of B-mode ultrasound in the localization of ampulla tumors was closely related to the examiner’s operation technique and experience. This paper believes that the accuracy of B-mode ultrasonography in the diagnosis of ampulla tumors is relatively high, reaching 86%, which is a valuable diagnostic tool.
