Elastography-based imaging techniques have received substantial attention in recent years for non-invasive assessment of tissue mechanical properties. These techniques take advantage of changed soft tissue elasticity in various pathologies to yield qualitative and quantitative information that can be used for diagnostic purposes. Measurements are acquired in specialized imaging modes that can detect tissue stiffness in response to an applied mechanical force (compression or shear wave). Ultrasound-based methods are of particular interest due to its many inherent advantages, such as wide availability including at the bedside and relatively low cost. Several ultrasound elastography techniques using different excitation methods have been developed. In general, these can be classified into strain imaging methods that use internal or external compression stimuli, and shear wave imaging that use ultrasound-generated traveling shear wave stimuli. While ultrasound elastography has shown promising results for non-invasive assessment of liver fibrosis, new applications in breast, thyroid, prostate, kidney and lymph node imaging are emerging.Here, we review the basic principles, foundation physics, and limitations of ultrasound elastography and summarize its current clinical use and ongoing developments in various clinical applications.

“…For few years, elastography has been used in adults to determine the tissue stiffness in tissues like the liver, kidney, lymph nodes, breast, prostate, pancreas and thyroid [17,18]. There are a number of scientific reports about the diagnostic value of elastography in the differentiation of thyroid nodules in adults; however, there are no studies on the applications of elastography in the diagnosis of thyroid gland in children [19,20,21,22].…”

Background: Ultrasound elastography is a noninvasive method of imaging based on the estimation of the mechanical properties of tissue. Data in adults indicate that decreased flexibility in comparison to the surrounding healthy tissue is characteristic of malignancy (in most thyroid carcinomas, except for follicular thyroid carcinoma). The purpose of our study was to assess the deformation of thyroid nodules and to evaluate the usefulness of elastography in predicting malignant thyroid nodules in adolescent patients. Methods: We examined 47 children with 62 thyroid nodules. All patients underwent elastography and fine needle aspiration cytology (FNAC). Results: Thirty-seven girls (79%) and 10 boys (21%) were included in the study. A strain ratio <2 was observed in 17 nodules (27% of the study group), a strain ratio between 2 and 4.9 in 34 nodules (55%) and a strain ratio >5 in 11 nodules (18%). According to cytological examination, 3 nodules (4.8% of the study group) were malignant. Two of them were hard (strain ratio ≥5), and 1 nodule had a strain ratio of 2. Conclusions: Our results suggest that elastography can be complementary to conventional ultrasonography and useful while making a decision about FNAC. At the same time, it should not replace the cytological assessment of thyroid nodules in children and adolescents.

“…Sonoelastography (SE) is a new imaging technique that measures the mechanical properties of tissue [14], and has seen early adoption as a non-invasive substitute for liver fibrosis staging [15][16][17][18][19][20][21], characterization of thyroid nodules [22][23][24], and localization of prostate cancer [24,25]. In this case report, we review a case of amyloidosis of the liver with findings seen on ultrasound shear wave elastography and also review the literature on the topic.…”

Amyloidosis is extremely rare, with an estimated 2225 new US cases reported annually. Signs and symptoms of the disease are subtle and imaging findings are not pathognomonic. Currently, diagnosis requires biopsy to demonstrate the deposition of amyloid. Elastography is a new imaging modality that evaluates tissue elasticity. It has shown to have efficacy in characterizing thyroid nodules, detecting prostate cancer, and staging liver fibrosis. We present a case of hepatic amyloidosis in a 51-year-old male that demonstrates significantly increased stiffness with a median value of 99.1 kPa (range 25.7-188.9 kPa) on shear-wave elastography (SWE) imaging, which is significantly higher than the cut-off range reported for cirrhosis on SWE (10.4-11.5 kPa). This finding raises the possibility that elastographic imaging may be sensitive to tissue mechanical changes induced by amyloid deposition.
