三维超声成像在胆道肿瘤诊断及手术可切除性评价中的应用

Clinical Application of Three-dimensional Ultrasonographic Lmaging in Diagnosis and Operation Excision of Biliary Tumers

目的:探讨三维超声在胆道肿瘤早期诊断、分型、手术可切除性评价及预后估计中的临床实际应用价值。方法:29例胆道肿瘤患者在常规二维超声检查后进行三维超声检查,三维超声重建图像与二维超声图像对比,确定是否可以获得更多的诊断信息。结果:所有患者可以准确地显示梗阻水平,三维超声可清晰地显示扩张的胆管树结构,包括肝内胆管、肝总管、胆囊以及胆总管。结论:三维超声重建可以更客观地显示胆管解剖,能够提供较二维超声更丰富的信息,对肿瘤早期诊断、分型、手术可切除性评价及预后估计有重要的临床意义。

Objective To evaluate the clinical value of three-dimensional ultrasonographic imaging diagnosis and operation excision in patients with biliary tumers. Methods 29 patients with biliary tumers underwent three-dimensional ul trasonographic imaging which were compared with the two-dimensional ultrasonographic imaging to determine whether additional diagnostic informations would be obtained. Results The level of obstruction was correctly dpicted in all patients. The dilated biliary duct tree structure.s were well visualized including dilated intrahepatic ducts, common hepatic ducts, gallbladder and common bile duct. Conclusions The biliary anatomy can be more objectively visualized on three dimensional ultrasonographic imaging which will provide more informations than those in the two-dimensional images for diagnosis andoperation treatment of biliary tumers.
