【摘要】 目的探讨超声造影(contrast enhanced ultrasonography,CEUS)对胆囊占位性病变的鉴别诊断价值。方法对30例常规超声拟诊为胆囊占位性病变的患者进行超声造影检查,观察病变的超声增强表现,并与病理结果进行对照。结果 30例患者中24例为胆囊良性病变,6例为胆囊癌,胆囊癌超声造影主要表现为不均匀性增强。常规超声诊断准确率、特异性及敏感度分别为53.3%、50.0%和66.7%;超声造影诊断准确率、特异性及敏感度分别为93.3%、91.7%和100%,二者比较差异有统计学意义(P<0.05)。结论 CEUS对胆囊占位性病变的鉴别诊断具有较高的价值。更多还原

【Abstract】 Objective To investigate the value of contrast enhanced ultrasonography(CEUS) in the differential diagnosis of gallbladder occupying lesions.Methods Totally 30 patients with gallbladder occupying lesions were detected using conventional ultrasongraphy and CEUS respectively.The features of lesions on CEUS were analyzed and compared with pathology findings.Results Among 30 cases,24 cases were benign and the remaining 6 cases were malignant.The accuracy,sensitivity and specificity were 53.3%,50.0% and 66.7% for conventional ultrasongraphy and 93.3%,91.7% and 100% for contrast-enhanced ultrasonography.There was significant difference between the two methods(P<0.05).Gallbladder carcinomas performed as heterogeneous enhancement in CEUS.Conclusion CEUS has a higher value in the differential diagnosis of gallbladder lesions.更多还原
