超声造影在胆管可疑占位性疾病中的应用

Application of contrast-enhanced ultrasonography in suspect occupied lesions of hepatic bile ducts

目的探讨超声造影在胆管可疑占位性疾病中的应用价值。方法5例胆管可疑占位性疾病患者接受超声造影检查。采用对比脉冲序列(CPS)成像技术,造影剂为SonoVue。结果1例胆总管下段癌注射造影剂后约23秒时见造影剂充填,持续50秒,而且病灶显示更清晰。1例胆泥和3例胆管结石始终未见造影剂进入。结论超声造影看来可鉴别胆管结石或胆泥和肿瘤,并有助于胆管微小病变的诊断。

Objective To discus the value of contrast-enhanced ultrasound in the diagnosis of suspect occupied lesions in hepatic bile duct. Methods Five patients with suspect occupied lesions in bile duet underwent contrast-enhanced ultrasound. The technique of contrast pulseed sequences （CPS） and the contrast agent SonoVue were used. Results One ease of common bile duet carcinoma showed early enhancement at 23s after injecting of contrast agent and the enhancement last 50s with even clear tumor margin. No enhancement was found in 1 ease of duetal mud and 3 cases of calculus of bile duct. Conclusions Contrast-enhanced uhrasonography can distinguish neoplasm from duetal mud and calculus, and is helpful to diagnose small duetal diseasases.
