Sonoelastography is based on the knowledge that some diseases, such as cancer, lead to a change in tissue hardness. Elastography examines the elastic properties of tissues by applying a slight compression to the tissue and comparing the images obtained before and after this compression. Endoscopic ultrasonography (EUS) is today the best technique to diagnose a small pancreatic mass and to determine the histology of such lesions. However, the accuracy of EUS-FNA is around 85-90%. In this study, elastography was used to differentiate benign from malignant pancreatic masses. The bright future of the second generation of elastography, the quantitative elastography or ratio elastography, is also discussed.
超声弹性成像基于这样的认识，即某些疾病（如癌症）会导致组织硬度发生变化。弹性成像是通过对组织施加轻微的压缩，并比较压缩前后获得的图像，来检查组织的弹性特性。内镜超声检查（EUS）是目前诊断胰腺小肿块和确定此类病变组织学的最佳技术。然而，EUS-FNA 的准确率约为 85-90%。在这项研究中，弹性成像被用于区分胰腺良恶性肿块。本文还讨论了第二代弹性成像（定量弹性成像或比值弹性成像）的光明前景。
