Elastography is an ultrasound-based newer imaging technique that is currently being used for the evaluation of breast lesions and hepatic pathology. It is also being evaluated for characterizing lesions of the prostate, thyroid, cervix and lymph nodes. We have applied real-time sonoelastography to a variety of musculoskeletal pathologies and here we report the findings of elastography for the e...

Elastography imaging is performed by subjecting the tissue under investigation to a form of mechanical excitation. The resultant tissue displacement vector is measured and can be used compute the spatial variation of strain within the tissue. These strain maps, known as elastograms, serve as surrogates for tissue elasticity. While elastography can be performed with any imaging modality, ultraso...

results of the 133 breast lesions, 32 were malignant and 101 were benign. in the differentiation of benign and malignant lesions, conventional us resulted in sensitivity of 100 %, specificity of 43.0 %, ppv of 57.1 %, npv of 36.7 %, and accuracy of 100 %. regarding swe, the sensitivity, specificity, ppv, npv, and accuracy values based on emax were 84.4 %, 89.1 %, 71.1 %, 94.7 %, and 88.0 %, res...

t a fi d T t p n r r l fi w N of Diagnostic and Interventional Imaging, to an emerging technique: ultrasound elastography. This issue provides the readers with information necessary to understand this new modality on the eve of its clinical expansion. Analogies with the development of pulsed wave and color Doppler modes are important, especially for techniques providing two-dimensional color-co...

UNLABELLED Nonalcoholic fatty liver disease (NAFLD) is one of the most common liver diseases in affluent countries. Accurate noninvasive tests for liver injury are urgently needed. The aim of this study was to evaluate the accuracy of transient elastography for the diagnosis of fibrosis and cirrhosis in patients with NAFLD and to study factors associated with discordance between transient elast...

Purpose: Ultrasound elastography is a new imaging procedure which allows the reconstruction of elasticity distribution by characterising the difference of hardness between pathological and normaltissue.Materials and Methods: The aim of our study was to apply real-time elastography during endoscopic ultrasound (EUS) examinations and to consequently characterise benign versus malignan...

Background: Ultrasound elastography displays information on tissue stiffness. Deep endometriotic nodules are hard fibrotic tissues. Patients recognized as having deep endometriosis only after several years from the onset of symptoms, therefore it is important to improve diagnostic capabilities. Cases: In this case series, our purpose was present applicability and feasibility transvaginal strain...

Cardiac magnetic resonance (MR) elastography noninvasively provides mechanics-based image contrast. The measurement of mechanical parameters is otherwise possible only by palpation or invasive pressure measurement. Measurement of parameters of myocardial shear stiffness is considered to be diagnostically beneficial especially in patients with diastolic dysfunction due to diffuse myocardial dise...

The World Federation for Ultrasound in Medicine and Biology (WFUMB) has produced guidelines for the use of elastography techniques including basic science, breast and liver. Here we present elastography in thyroid diseases. For each available technique, procedure, reproducibility, results and limitations are analyzed and recommendations are given. Finally, recommendations are given based on the...

Recently, Elastography has been introduced for prostate cancer imaging. Elastography is an imaging technique that evaluates the elasticity of the tissue. Krouskop et al. reported that cell density was greater in neoplastic tissue, which causes a change in tissue elasticity / stiffness. Ophir et al. first described the principle of this technique in 1991. To reduce the time-consuming calculation...
