Typically both breast and prostate cancer present as tissue with decreased elasticity. Palpation is the oldest technique of tumor detection in both organs and is based on this principle. Thus an operator can grade a palpable mass as suspicious for cancer. Strain elastography as modern ultrasound technique allows the visualization of tissue elasticity in a color coded elastogram and can be understood as technical finger. The following article shows similarities and differences of ultrasound strain elastography in the diagnosis of breast and prostate cancer.
• In prostata cancer elastography, in breast cancer B-mode is the primary sonographic search modality. • The diagnostic value of the search modalities change with increasing age.• A cut-off value for a strain ratio is hard to obtain in the elastography of the prostata, because there is no stabile reference tissue in the prostata.
通常情况下,乳腺癌和前列腺癌均表现为弹性降低的组织。触诊是这两个器官中最古老的肿瘤检测技术,且基于此原理。因此,操作者可将可触及的肿块判定为可疑癌。应变弹性成像作为一种现代超声技术,能在彩色编码弹性图中显示组织弹性,可被视为技术上的手指。以下文章展示了超声应变弹性成像在乳腺癌和前列腺癌诊断中的异同。
• 在前列腺癌弹性成像中,在乳腺癌中B超是主要的超声检查方式。• 随着年龄增长,检查方式的诊断价值会发生变化。• 在前列腺弹性成像中很难获得应变比的临界值,因为前列腺中没有稳定的参照组织。
