目的探讨超声对胆囊息肉、胆囊腺瘤、胆囊癌鉴别诊断价值。方法分析571例胆囊息肉、30例胆囊腺瘤、109例胆囊癌灰阶超声(BUS)与彩色多普勒血流显像(CDFI)的声像图特征。结果胆囊息肉、胆囊腺瘤、胆囊癌的大小、彩色血流分级、动脉血流峰值流速(Vmax)和阻力指数(RI)等均差异有显著意义,如以RI≤0.65作为诊断恶性病变的指标,较有特异性。结论BUS联合CDFI是鉴别胆囊息肉样病变的有效方法。
Objective To investigate the differential diagnosis of gallbladder polyps, gallbladder adenoma and gallbladder carcinoma by ultrasound. Methods 571 cases of gallbladder polyps, 30 cases of gallbladder adenoma, 109 cases of gallbladder carcinoma with gray scale ultrasound (BUS) and color Doppler flow imaging (CDFI) sonographic features. Results There were significant differences in gallbladder polyps, gallbladder adenoma, gallbladder carcinoma size, color flow grade, Vmax, and RI. For example, RI≤0.65 was used as an index to diagnose malignant lesions , More specific. Conclusions BUS combined with CDFI is an effective method to distinguish polypoid lesions of gallbladder.
