Palpation has been used by doctors for centuries to aid in the diagnosis of disease or illness. Today, ultrasound elastography is extending palpation to organs located beyond the reach of physical touch, providing new opportunities for diagnosis and the noninvasive assessment of disease. There are two commercially available techniques for ultrasound elastography: strain and shear wave. Although ultrasound systems providing strain elastography have been available longer than shear wave, the latter is quickly gaining traction as the preferred technique. Richard G.

Lymphedema is a chronic condition characterized by the accumulation of protein-rich liquid in the interstitial space of tissues caused by the inability of the lymphatics to transport lymph fluid back to the lymphatic system 1. The National Cancer Institute predicts that there will be almost 4 million breast cancer survivors by January 3 , and as a result, the incidence of BCRL will increase. Potential causes related to BCRL include radiotherapy and lymph node biopsy or dissection 1 , 4. Diagnosis is mostly clinical 5 , and it has been classified into four stages by the International Society of Lymphology based on clinical characteristics. Stages 0 and I correspond to the early accumulation of high protein fluid, and pitting may occur. Stages II and III involve fibrosis, fat deposits, and trophic skin changes, and pitting starts to disappear 6. Currently, there is no specific tool for diagnosis at early stages when symptoms have not appeared.
Breast elastography: A literature review
Ultrasound elastography is a relatively new diagnostic technique for measuring tissue elasticity hardness. This review describes the types and evaluation methods of elastographies used in diagnosing pancreatic tumors. It also evaluates the diagnostic ability of transabdominal US or endoscopic ultrasonography EUS elastography for pancreatic tumors, based on findings from a search of published articles.
Breast cancer is the most frequently diagnosed cancer and the chief cause of cancer death among women worldwide, with an estimated 1. Ophir et al raised the concept of ultrasound elastography in The first practical diagnostic equipment was released in Breast ultrasound elastography is an emerging sonographic imaging technique which provides information on breast lesions in addition to conventional ultrasonography US and mammography.
