摘要
目的探讨双重超声造影在胃肠间质瘤病变中的应用价值。方法回顾分析70例胃肠间质瘤,术前均行双重超声造影,并与病理结果对比分析。结果 70个间质瘤分布于胃底24个,胃窦15个,胃体小弯侧12个,胃体大弯侧8个,十二指肠6个,直肠5个。GIST主要造影特征为肿瘤周边环状高增强,内部呈低或高增强。结论 GIST的双重超声造影表现具有一定的特征性,对患者的术前诊断、手术方式的选择及术后随访具有重要价值。
Objective To evaluate the application value of double contrast-enhanced ultrasound （DCUS）in the diagnosis of gastrointestinal stromal tumor （GIST）. Methods A total of 70 cases of gastrointestinal stromal tumor （GIST） were retrospectively ana- lyzed. The patients were all undergone DCUS and the results were compared with that of pathology. Results There were 70 lesions located in fundus of stomach, 15 in antrum, 12 in lesser curvature,8 in greater curvature,6 located in duodenum and 5 in rectum. The ultrasound characteristics of GIST were a ring-like enhanced contrast around the tumor with inside hyper or hypo-enhanced contrast. Con-clusion The DCUS of GIST has a certain characteristics that have an important value in pre-operative diagnosis, selection of operation approach and post-operative follow-up.
