摘　　要：目的探讨超声造影诊断胃间质瘤的价值。方法本院门诊或住院患者21例,经口服高回声型的胃超声造影剂,显示胃壁肿块,其中4例给予经静脉的双重超声造影(口服胃超声造影剂加静脉注射SonoVue对胃肿块血流灌注进行观察)。结果 21例肿瘤均为单发,经口服超声造影表现为低回声或近似无回声肿物,瘤体大小为3～9.3cm,平均(4.1±1.4)cm,其内可探及血流信号。双重超声造影提示良性病变3例,恶性病变1例,均与手术病理结果相符合。超声造影提示恶性胃间质瘤4例,与手术病理符合率为80.0%(4/5),良性胃间质瘤15例,符合率为93.75%(15/16),提示良性可能性大和恶性可能性大者各1例。胃镜检出16例,活检提示良性胃间质瘤13例,恶性3例,与手术病理符合率为100%,2例肌壁间型和3例腔外型未检出。手术病理结果为恶性间质瘤5例,良性16例。结论超声造影诊断胃间质瘤有较高的临床价值,可作为临床诊断的首选方法。Objective To evaluate the clinical value of contrast-enhanced ultrasonography in diagnosis of gastric stromal tumors.Methods A total of 21 outpatients or inpatients in our hospital,which were diagnosed as gastric tumor by oral highecho-type gastric ultrasound contrastagent,were included,in which4 cases were treated by double contrast-enhanced ultrasonography(DCUS,oral and intravenous contrast agent SonoVue).Results All of the tumors in the 21 patients were single and shown as hypoechoic or nearly anechoic m...
