目的:探讨三维超声成像在胆总管结石及胆总管癌诊断中的临床应用价值。方法:对22例扩张胆总管进行三维超声成像,描述了胆总管内结石及胆总管癌病变的立体图像特征。图像采集方法为磁场空间定位自由扫查。结果:三维超声成像所见图像逼真清晰、形态直观、立体感强,并可确定病变的部位、范围和其表面结构,尤其是胆总管癌对胆总管壁的浸润情况。结论:三维超声成像对胆总管病变的诊断及制定方案提供更为丰富的信息。
Objective: To investigate the clinical value of three-dimensional ultrasonography in the diagnosis of common bile duct stones and common bile duct cancer. Methods: Three-dimensional ultrasound imaging was performed on 22 patients with dilated common bile ducts. The stereoscopic image features of common bile duct stones and common bile duct cancer lesions were described. The image acquisition method is a magnetic space spatial positioning free scan. RESULTS: The three-dimensional ultrasound images showed vivid images, intuitive morphology and strong stereoscopic effect. The location, extent and surface structure of the lesions could be determined, especially the common bile duct carcinoma infiltrating the common bile duct. Conclusion: Three-dimensional ultrasound imaging provides more information for the diagnosis and formulation of common bile duct lesions.
