摘　　要：目的探讨超声造影在鉴别诊断胆囊良恶性疾病中的价值。方法回顾分析应用对比脉冲序列成像技术和SonoVue超声造影检查117例胆囊病变的特征,比较胆囊良恶性病变常规超声和超声造影的诊断符合率。结果除胆泥无造影剂进入外,胆囊良恶性病灶在达峰时多表现为高增强、富血供;消退时胆囊癌为低增强,良性病灶多为等增强。对于胆囊癌,常规超声的诊断符合率为65.38%,超声造影为92.31%;胆囊良性病灶,常规超声的诊断符合率为82.41%,超声造影为93.41%。结论超声造影可提高超声诊断胆囊疾病的准确率,可鉴别胆泥沉积与胆囊癌,了解胆囊癌侵犯胆囊壁的程度及肝内转移情况,但对于腺瘤和单发息肉以及直径小的胆囊癌鉴别较困难。Objective To investigate the value of contrast - enhanced ultrasound （CEUS） in differential diagnosis of benign and malignant gallbladder disease. Methods The characteristic of 117 patients with gallbladder disease examined by CEUS with SonoVue and contrast pulse sequence imaging technique were retrospectively analyzed. The diagnose accordance rate of benign and malignant gallbladder disease between convention ultrasound and CEUS was compared. Results Besides biliary sludge was non - enhancement, benign and malignant gallbladder diseases were mostly hyper - enhancement with abundant blood supply, gallbladder cancer was hypo - enhancement, and benign gallbladder disease mostly was iso - enhancement when contrast agent was extincted. The diagnose accordance rate of gallbladder cancer was 65.38% and 92.31% by convention ultrasound and CEUS respectively. The diagnose accordance rate of gallbladder benign disease was 82.41% and 93.41% by conventional ultrasound and CEUS respectively. Conclusion Contrast - enhanced ultrasound can improve the diagnose accordance rates of gallbladder diseases, it can discriminate biliary sludge and gallbladder cancer and obtain the invasion degree of gallbladder wall and liver metastasis. While it is difficultt for differential diagnosis of gallbladder adenoma, polypus, and gallbladder cancer with small diameter.
