摘要 【目的】探讨彩色多普勒超声在胆囊癌诊断中的应用价值。【方法】经C T、M RI、病理诊断和随访证实的24例胆囊癌患者采用彩色多普勒超声进行诊断鉴别,检测病灶大小、边界、形态和回声特性,以及血流信号的有无、出现的部位和性质以及血流参数,并与20例无胆囊疾病的患者胆囊壁的血流参数进行分析比较。【结果】在彩色多普勒超声表现中胆囊癌患者胆囊动脉收缩期最大流速(PSV ),舒张期最低流速(EDV ),平均流速(Vmean)和阻力指数(RI)分别为(30.4±4.3) cm/s ,(8.8±6.1) cm/s ,(14.6±5.2) cm/s和(0.71±0.21),明显高于正常对照组,分别为(14.3±2.7)cm/s ,(4.4±3.8)cm/s ,(6.1±3.4)cm/s和(0.46±0.23),差异有统计学意义( P <0.01)。以胆囊动脉PSV≥20cm/s进行胆囊癌良恶性的判断标准界值指标,其敏感性、特异性、准确性、阳性预测值、阴性预测值及约登指数,分别为87.50%、95.00%、90.91%、95.45%、86.36%、0.825。【结论】彩色多普勒超声所反映的血流信号结合声像图对于胆囊癌患者病情的诊断具有重要的临床应用价值。 [Objective]To explore the value of color Doppler ultrasound used in the diagnosis of gallbladder carcinoma .[Methods]Color Doppler ultrasound was used for the differential diagnosis of 24 patients with gallblad-der carcinoma diagnosed by CT ,MRI ,pathology and follow up .The tumor size ,boundary ,shape ,echo feature , blood flow signal and its location and character and hemodynamic parameters were examined and compared with those of gallbladder wall of 20 patients without gallbladder disease .[Results]Color Doppler ultrasonic manifesta-tions showed that peak systolic velocity (PSV) ,end diastolic velocity(EDV) of artery ,mean velocity(Vmean) and resistance index (RI) in gallbladder carcinoma group were (30 .4 ± 4 .3)cm/s ,(8 .8 ± 6 .1)cm/s ,(14 .6 ± 5 .2)cm/s and (0 .71 ± 0 .21) respectively ,which were obviously higher than those in normal control group[(14 .3 ± 2 .7)cm/s ,(4 .4 ± 3 .8)cm/s ,(6 .1 ± 3 .4)cm/s and (0 .46 ± 0 .23) ,respectively] ,and there were significant differences( P〈0 .01) .The differential diagnosis indicator was gallbladder artery PSV ≥0 .20cm/s .The sensitivity ,specificity , accuracy ,positive predictive value ,negative predictive value and Youden index were 87 .5% ,95 .0% ,90 .91% , 95 .45% ,86 .36% and 0 .825 ,respectively .[Conclusion] Blood flow signal showed by Color Doppler ultrasound combined with ultrasonogram in the diagnosis of patients with gallbladder has an important useful value .
