A evaluation of contrast-enhanced harmonic endoscopic ultrasonography by using a second-generation contrast agent in pancreatic solid tumors

在这项研究中，我们的目的是评价对比增强谐波超声内镜使用第二代造影剂在胰腺实体瘤的价值。将增强模式与总共133个胰腺实体瘤的最终诊断进行比较。根据增强模式组合诊断胰腺癌的敏感性、特异性和准确性分别为94%、89%和92%。结论：谐波超声内镜对胰腺实性肿瘤的诊断具有重要价值。

In this study, we aimed to evaluate the value of contrast-enhanced harmonic endoscopic ultrasonography by using a second-generation contrast agent in pancreatic solid tumors. The enhancement patterns were compared with the final diagnosis of a total of 133 pancreatic solid tumors. The sensitivity, specificity, and accuracy of diagnosis based on combinations of enhancement patterns were respectively, 94%, 89%, 92% for pancreatic carcinoma. We conclude that contrast-enhanced harmonic endoscopic ultrasonography is useful modality for different diagnosis of pancreatic solid tumors.
