Palpation of organs is one of the oldest clinical examination techniques, for instance, if you think of the palpation of the breast or the digital rectal examination of the prostate, where hard palpable regions are suspicious for cancer. This is the basic principle of real-time elastography, an ultrasound technique, which is able to visualise tissue elasticity. Since prostate cancer features an increased stiffness due to the higher cell and vessel density than the normal surrounding tissue, real-time elastography has been used for several years for prostate cancer detection. This review introduces the different techniques of ultrasound elastography and furthermore summarises its limitations and potentials.
器官触诊是最古老的临床检查技术之一，例如，想想乳房触诊或前列腺指诊，可触及的硬结区域可能提示癌症。这就是实时弹性成像的基本原理，它是一种能够显示组织弹性的超声技术。由于前列腺癌细胞和血管密度高于周围正常组织，因而硬度增加，实时弹性成像已用于前列腺癌检测数年。本文综述了超声弹性成像的不同技术，并总结了其局限性和潜力。
