AbstractUltrasound elastography (USE) is becoming an important adjunct tool in the evaluation of various musculoskeletal (MSK) traumatic conditions and diseases, with an increasing number of applications and publications in recent years. This rapidly evolving technique enhances the conventional ultrasound (US) examination by providing information on the elastic properties of tissue alongside the morphological and vascular information obtained from B-mode US and Doppler imaging. Those performing USE must have basic knowledge of its proper imaging techniques and limitations. In this review article, we place the USE in historical perspective and discuss basic techniques and current applications of USE in the evaluation of various traumatic and pathologic conditions of fasciae, nerves, muscles, tendons, ligaments, and MSK soft tissue masses.

Breast cancer has a high mortality rate and caused about 13.7% of all cancer types deaths in women. Mammography imaging, having a good sensitivity to cancer, is used along with biopsy in a routinely manner, to differentiate between malignant and benign masses. Biopsy is an invasive procedure, and to reduce the necessity for performing it, ultrasound elastography was proposed. Elastography is a potential imaging technique to characterize breast masses, and to differentiate malignant from benign lesions, based on imaging estimated tissue strains under compression. This can result in lowering the number of unnecessary biopsies. Using 3D elastography, lesion relative stiffness with the surrounding soft tissue is estimated at different compression levels, and used as a classification parameter to judge the malignancy of the lesion. In addition, elastography provided a means of emphasizing the strain difference of the lesion from the surrounding soft tissue, which can be used as an additional classification parameter. A pilot study on volunteered patients was performed, and results were compared with biopsy diagnosis as a reference. Initial elastography results showed good agreement with biopsy outcomes. Moreover, we constructed different strain elastograms including first principal, maximum shear and von Mises strains. Those new types of elastographic volumes incorporated the normal axial and shear strains together, which provided better distinction of the hard lesion from the soft tissue. In summary, the proposed elastographic techniques can be used as a noninvasive quantitative characterization tool for breast cancer, with the capability of visualizing and separating the masses in three dimensional space.

Összefoglaló. Az ultrahang-elasztográfia az elmúlt évek során egyre növekvő figyelmet kapott a lágyszövetek elaszticitásának vizsgálatában. A módszer használatát az teszi szükségessé, hogy egyes, a mechanikai tulajdonságaikban különböző szövetek hasonló echogenitásúak lehetnek, valamint hogy egy adott szövet megváltozott struktúrája vagy mechanikai tulajdonsága nem minden esetben jár együtt a szövet hagyományos ultrahangképének megváltozásával. Az elmúlt évtizedben a deformációs és a nyírási ultrahang-elasztográfia vált széles körben elérhetővé. Ezen új képalkotási technika egyre nagyobb szerepet tölt be a szülészeti-nőgyógyászati ultrahang-diagnosztikában is. A nőgyógyászatban szerephez juthat az endometriosis és az adenomyosis kimutatásában, valamint a benignus és a malignus cervicalis és ovarialis képletek elkülönítésében. A nőgyógyászathoz hasonlóan a szülészetben is jelentős változást hozhat az ultrahang-elasztográfia: alkalmas lehet a szülésindukció sikerességének, a koraszülés bekövetkezésének és a praeeclampsia kialakulásának előrejelzésére. Orv Hetil. 2021; 162(18): 690–695. Summary. Ultrasound elastography has received significant attention for the assessment and measurement of soft tissue elastic properties in recent years. The advantage of ultrasound elastography lies in the fact that two different tissues can share similar echogenicities but may have other mechanical properties or, on the contrary, mechanical abnormalities of a designated tissue do not necessarily go hand in hand with an altered appearance on a conventional ultrasound image. In the last decade, strain and shear-wave elasticity imaging methods have become the most widely available among commercial ultrasound equipments. The importance of this new method expands rapidly also in the field of obstetrics and gynecology. Ultrasound elastography has a promising role in the diagnosis of endometriosis and adenomyosis and helps to differentiate benign and malignant cervical and ovarian lesions. The use in the prediction of the outcome of labor induction and preterm birth, and in the evaluation of preeclampsia are emerging. Orv Hetil. 2021; 162(18): 690–695.

Objectives. Various elastography techniques have been proffered based on linear or nonlinear constitutive models with the aim of detecting and classifying pathologies in soft tissues accurately and noninvasively. Biological soft tissues demonstrate behaviors which conform to nonlinear constitutive models, in particular the hyperelastic ones. In this paper, we represent the results of our steps towards implementing ultrasound elastography to extract hyperelastic constants of a tumor inside soft tissue. Methods. Hyperelastic parameters of the unknown tissue have been estimated by applying the iterative method founded on the relation between stress, strain, and the parameters of a hyperelastic model after (a) simulating the medium’s response to a sinusoidal load and extracting the tissue displacement fields in some instants and (b) estimating the tissue displacement fields from the recorded/simulated ultrasound radio frequency signals and images using the cross correlation-based technique. Results. Our results indicate that hyperelastic parameters of an unidentified tissue could be precisely estimated even in the conditions where there is no prior knowledge of the tissue, or the displacement fields have been approximately calculated using the data recorded by a clinical ultrasound system. Conclusions. The accurate estimation of nonlinear elastic constants yields to the correct cognizance of pathologies in soft tissues.
