Ultrasound elastography enables in vivo measurement of the mechanical properties of living soft tissues in a non-destructive and non-invasive manner and has attracted considerable interest for clinical use in recent years. Continuum mechanics plays an essential role in understanding and improving ultrasound-based elastography methods and is the main focus of this review. In particular, the mech...

Ultrasound (US) elastography measures the deformation of tissue in response to applied force to derive and display its stiffness. It has been applied to various organs and tissues, e.g., as an adjunct tool to conventional US and X-ray mammography in the detection and characterization of breast masses. Real-time US elastography processing is demanding due to several computationally-expensive mod...

Elastography is a new technique for evaluating the stiffness of nodules. It is generally recognised that malignant thyroid lesions are harder than benign lesions. Different elastographic techniques are presented, with characteristics, advantages and limita‐ tions. Qualitative and semiquantitative methods are described. Comparison of the main existing techniques, static and dynamic elastographie...

BACKGROUND Elastography is an imaging technique, which displays the hardness of soft tissue, by showing the behavior of tissue when subjected to mechanical stress. The purpose of this study was to assess the role of ultrasound elastography in differential diagnosis of breast lesions. MATERIALS AND METHODS A prospective study was conducted in our Research Centre, University of Medicine and Pha...

OBJECTIVE We aimed to evaluate the predictive value of elastography in determining malignancy during preoperative investigation of thyroid nodules and to compare its results with preoperative fine-needle aspiration biopsy (FNA) and postoperative histopathology results. MATERIAL AND METHODS Among the group of patients who had indications for thyroidectomy between January 2013- September 2013 i...

Definitely, contrast and elastography have been the two words prevailing in the ultrasonography research literature of the last decade. Of these, elastography did cast a special charm over the researchers, due to its ever increasing number of technological approaches. A major role was also played by the adaptability of the method(s) to virtually all applications of ultrasonography and even the ...

BACKGROUND In vivo detection of vulnerable plaques is presently limited by a lack of diagnostic tools. Intravascular ultrasound elastography is a new technique based on intravascular ultrasound and has the potential to differentiate between different plaques phenotypes. However, the predictive value of intravascular elastography to detect vulnerable plaques had not been studied. METHODS AND R...

Elastography is emerging as an imaging modality that can distinguish normal versus diseased tissues via their biomechanical properties. This paper reviews current approaches to elastography in three areas—quasi-static, harmonic and transient—and describes inversion schemes for each elastographic imaging approach. Approaches include first-order approximation methods; direct and iterative inversi...

Background: Ultrasound is the modality of choice for evaluation of thyroid nodules. Elastography plays a complimentary role in characterizing the thyroid nodules. Objectives: This study is undertaken to evaluate the role of Elastography in evaluation and characterization of the thyroid nodules. Materials and methods: Fifty cases of thyroid nodules who underwent ultrasound evaluation during Marc...

Although elastography can enhance the differential diagnosis of thyroid nodules, its diagnostic performance is not ideal at present. Further improvements in the technique and creation of robust diagnostic criteria are necessary. The purpose of this study was to compare the usefulness of strain elastography and a new generation of elasticity imaging called supersonic shear wave elastography (SSW...
