Aim: This study was designed to assess the possible usefulness of shear-wave elastography in differentiating between benign and malignant tissue in prostate neoplasia. Patients and methods: A total of 120 prostate tissue samples were obtained from 10 patients treated by radical prostatectomy and investigated pre-operatively by ultrasound elastography followed by directed biopsy. After resection, whole-mount sectioning and histological examination was performed. The predictions based on shear

Shear wave elastography
Shear wave elastography (SWE) is an increasingly explored ultrasound (US) technique that measures elastic tissue properties. This technique can add information to the conventional gray-scale and Doppler US techniques, providing a quantitative assessment of tissue

technique of quantitative elastography. ARFI correlates tissue flexibility with conventional gray-scale images obtained by US. Shear wave velocity (SWV) is measured by ARFI to establish the stiffness of tissues in meters per seconds (m/sec). With gradually increasing acoustic frequencies, tissues fail to respond in time to the transitions between positive and negative pressures, and the motion becomes out of phase with the acoustic wave frequency. As a result, energy is deposited in the tissues, which

Although grayscale, color and power Doppler US show sonographic features of some specific diagnosis, it is challenging in many cases to differentiate between benign and malignant tumors. Also, it is difficult to make a distinction between pleomorphic adenomas and Warthin tumors, which are the most common parotid gland tumors(2,3).

diseases). There is a need of a practical study for the diagnosis and follow-up of ON patients(7). Elastography is a non-invasive ultrasonographic (US) technique for evaluating the elastic properties of tissues, and shear wave elastography (SWE) uses waves that are generated by transducers and interact with the tissue(8).
In the present study, we attempt to determine the optic nerve findings and diagnostic performance of SWE as an alternative to MRI in patients with ON.

Aim: This study was designed to evaluate the performance of shear-wave elastography as a diagnostic tool for prostate cancer in a larger cohort of patients than previouslyreported. Patients and methods: Seventy-three patients with suspected prostate carcinoma were investigated by ultrasound elastography followed by directed biopsy. The elastographic and histological results for all biopsies were compared. Results: After exclusion of invalid and non-assessable results, 794 samples were obtained

Non-invasive methods for liver stiffness assessment have been introduced over recent years. Of these, two main methods for estimating liver fibrosis using ultrasound elastography have become established in clinical practice: shear wave elastography and quasi-static or strain elastography. Shear waves are waves with a motion perpendicular (lateral) to the direction of the generating force. Shear waves travel relatively slowly (between 1 and 10 m/s). The stiffness of the liver tissue can be

both safe and noninvasive(10).
Elastography can be done with an ultrasonic transducer in combination with shear wave techniques such as TE, point shear wave elastography (pSWE), and two-dimensional shear wave elastography(11,12). The main restriction of TE in clinical practice is the high amount of uninterpretable outcomes(13). Shear wave elastography (SWE) is an innovative method that is based on shear waves applied on a diagnostic ultrasound system(14). SWE has the benefit of being able to image

Aim of the study: Since there have been only few works reporting the diagnosis of kidneys using Acoustic Radiation Force Impulse technique and those works do not provide consistent results of shear wave velocity measurements in renal tissue, we have decided to use kidney phantoms with known properties to examine the reliability of the method itself in a controlled setup similar to kidneys examination. Materials and methods: Four gelatin-based phantoms imitating different clinical situations

The newer and non-invasive imaging techniques of transient elastography (TE) and shear-wave elastography (SWE) provide the opportunity to detect hepatic fibrosis and are a safe and reliable alternative to liver biopsy(18). Furthermore, TE and SWE are reproducible and quantifiable measures of liver stiffness. Using an

a significant recovery of shoulder range of movement(5,11,12). Recent studies have also shown that the stiffness of the CHL can be assessed using shear wave elastography(13–15). Shear wave elastography is a relatively new technique to non-invasively provide quantitative information regarding tissue elasticity in real time based on their viscoelastic properties. The ultrasound system propagates shear waves into tissues and assesses their elastic modulus. This has been used in a variety of

The next step in the development of ultrasound palpation was to apply the local remote tissue compression by using the acoustic radiation force generated through the special beam forming of the ultrasonic beam probing the tissue. The acoustic radiation force causes a slight deformation the tissue thereby forming a shear wave propagating in

In addition to morphological features, ultrasound imaging combined with strain and shear wave elastography can also provide information on the mechanical properties of intact and diseased muscle tissue, thus allowing assessment of muscle biomechanics in the clinical setting(9–16). Strain

In the last few years, notable technical progress has taken place in ultrasound elastography. Qualitative methods have been replaced by quantitative ones, such as: transient elastography, acoustic radiation force impulse and shear wave elastography. Owing to the fact that the spleen is superficially located, it is possible to obtain reliable measuring accuracy of its hardness using sonoelastography. Lately, many researchers have been investigating how spleen elasticity changes in patients
