Abstract:

In the approaches to elastography, two mathematical operations have been frequently applied to improve the final estimate of shear wave speed and shear modulus of tissues. The vector curl operator can separate out the transverse component of a complicated displacement field, and directional filters can separate distinct orientations of wave propagation. However, there are practical limitations that can prevent the intended improvement in elastography estimates. Some simple configurations of wavefields relevant to elastography are examined against theoretical models within the semi-infinite ela

Abstract:

Ultrasound elastography including transient elastography (TE), point shear wave elastography, (pSWE) and two (three)- dimensional shear wave elastography (2D-SWE) have been introduced mainly for the evaluation of the liver. All the techniques are also feasible for the examination of spleen, whereas pSWE and 2D-SWE can be used for the assessment of the pancreas, kidney, gastrointestinal tract and other organs. Strain elastography also plays a role for non-liver applications. The aim of the current report is to highlight unique features and techniques for the elastographic examinations in childr

Abstract:

There has been great interest in the development of non-invasive techniques for the diagnosis of liver fibrosis in chronic liver diseases, including ultrasound elastographic methods. Some of these methods have already been adequately studied for the non-invasive assessment of diffuse liver diseases. Others, however, such as two-dimensional Shear Wave Elastography (SWE), of more recent appearance, have yet to be validated and some aspects are for the moment incompletely elucidated. This review discusses some of the aspects related to two-dimensional SWE: the examination technique, the examinati

Abstract:

AbstractElastography is the noninvasive method of qualitative and quantitative evaluation of strain and elastic modulus distribution in soft tissues. In simpler terms, elastography is the science of measuring tissue stiffness, the deviation of which correlates with pathology of the tissue/organs being evaluated. Whereas, elasticity, refers to the property of solid matter to return to their original shape and size after removal of the deforming forces. In all forms of elastography, irrespective of the types of deforming forces or moduli, the deformation of tissue occurs in the form of shear def

Abstract:

Transient elastography (TE) is a clinically available ultrasound elastography technique in which mechanical vibration of a small piston at the tissue surface generates a short shear wave pulse that propagates into the body. The piston doubles as an ultrasonic transducer; thus, the shear wave propagation is measured with pulse-echo ultrasound along the beam axis, yielding the wave speed and tissue stiffness. The long shear wavelength compared to piston diameter used in current devices results in low shear wave signal that decays rapidly on axis as the shear wave spreads in all directions, thus

Abstract:

Despite that esophageal varices can be effectively detected by using upper gastrointestinal tract endoscopy, the procedure is invasive and requires the integration of adequate experience and training, and it is not suitable for many patients. Accordingly, ultrasound elastography has been developed and validated by many studies in the recent literature as effective and non-invasive modalities for the early observation and diagnosis of esophageal varices and the relevant hepatic diseases. In this study, we aim to conduct a literature review to furtherly elaborate on the role and validity of elas

Abstract:

Shear wave elastography (SWE) relies on the generation and tracking of coherent shear waves to image soft tissue’s shear elasticity. However, coherent shear wave tracking is not always possible due to scattered or interfering waves that arise from inhomogeneities, muscular activity, heart beating, or external sources. To overcome this limitation, we developed an alternative approach using a complex elastic wave-field. Based on the analogy between time reversal and seismic noise correlation, this complex field is “transformed” into a coherent converging-diverging time-reversal field using spati

Abstract Purpose: To date, MRI remains the gold standard for the diagnosis of breast implant rupture. As MRI is an expensive procedure with limited availability, improvement in sonographic assessment is desirable. A potentially useful tool in this regard is the assessment of tissue stiffness using ultrasound elastography. Strain elastography provides a qualitative analysis by producing a coloured map in the B-mode image comparing the stiffness of adjacent tissues in the region of interest, whereas shear wave elastography provides a quantitative analysis.

Abstract:

Shear wave elastography with ultrasound is a noninvasive method used for measuring stiffness in the human body. Shear wave elastography can be used for accurately and quantitatively measuring stiffness. However, its disadvantage is that the stiffness value can vary significantly because the region of interest (ROI) setting depends on the diagnostic operator. In this study, a stiffness measurement program using color mapping in shear wave elastography was developed to address the above-mentioned disadvantage. Color map and color ratios were obtained and evaluated for major lower limb muscles (i
