“…The specificity of ultrasound alone ranges between 7.1-98.8%. 1 The positive predictive value was 8.4-13.7% for biopsies performed as a result of screening studies which is much lower than the optimal positive predictive value of 25-40% achieved at mammographic screening. 2 Since then other modalities have been investigated to aid in distinguishing benign from malignant diseases.…”

Background: To presenting with breast lumps are very common in surgical practice and the routine use of ultrasound in the diagnosis is well validated. But there are gray zones in equivocal cases which increase the number of negative biopsies. To increase the sensitivity and specificity of ultrasound by adding another non-invasive modality, namely strain elastography, can reduce this rate. To evaluate the sensitivity and specificity of strain elastography in the diagnosis of breast masses.Methods: As part of the triple assessment patients presenting with breast lumps underwent ultrasonography and strain elastography, where strain ratios were calculated. Based on which they either underwent percutaneous biopsy or surgical excision. A total of 30 patients with breast lesions underwent sonomammogram in which the breast lesions were both graded with BIRADS and also the elastography and strain ratio was calculated.Results: Strain ratio has higher sensitivity and specificity which makes it a valid diagnostic tool in the evaluation of breast masses.Conclusions: It can also help in reducing the number of benign lesion biopsies and also reduce the number of negative biopsies. Being a non-invasive modality, it is much more patient compatible and economically cheaper when compared with MRI and modalities.

“…Sonoelastography arises as a non invasive method of imaging to evaluate tissue stiffness, it has been used to improve diagnostic confidence and increased specificity of conventional sonography. Therefore unnecessary short term follow up or biopsies were able to be reduced [34][35][36].On the other hand, SWE measured tissue stiffness by Young´s modulus (as we defined before) which is expressed in pressure units, usually in kilopascals (kPa). In SWE, shear waves created by ultrasound system propagate in tissue at speeds of 1-10mm/ sec, equivalent to a 1-300kPa.…”

Objective: Make a literature review of breast elastography, an imaging technique not so new today, for many still unknown in diagnostic ultrasound, which emerges in order to characterize complementarily tissues of the breast, contributing to differential diagnosis between benign and malignant lesions.Review: Today breast cancer is by far the most common cancer in women. Mammography and ultrasound has become an indispensable diagnostic tandem within the breast image, increasing the sensitivity of ultrasound mammography by 15% and both techniques are able to characterize most breast lesions. Using these techniques together we achieve a sensitivity of 85-100% and a specificity of 76-80%, specially in dense breasts where mammography is significantly limited [1]. Copyright: ©2017 Fernadez Keywords: We can distinguish two types of elastographyCompression elastography and "shear-wave" elastography (SWE).Compression elastography (strain) produces an image based on the displacement of the tissue from an external or patient source, and the movement of the tissue shows the direction of US beam propagation. This technique allows a qualitative assessment of the lesion. With real-time ultrasound elastography, the physical properties of soft tissue are revealed through characterization of the differences in stiffness between the region of interest and the surrounding tissue based on mechanically induced deformation (strain) of structures during B-mode scanning [8].Data acquisition and interpretation of elasticity images are largely dependent on the examiner´s experience, and significant interobserver variability has been found [3,4,13,14]. The real-time elastogram is displayed with a scale based on the relative strain of the tissues. The technique to obtain the optimal images varies with the algorithm used by the manufacturer of the ultrasound system. Monitoring of the B-mode image to confirm the lesion is only displaced in depth during scanning and otherwise moving in the field of view (FOV) will allow optimal images. With the displacement technique, one cannot be surveying the breast; scanning must be done in one stationary position.Modern US devices allow combined elasticity and 2D real time assessment of tissues or lesions, using the same probe as conventional ultrasound imaging [15]. Sonoelastography demonstrates the elasticity of a lesion related to the elasticity of the surrounding tissue [13], so the final result is based on the comparison between pre and postcompression data [10,15,16], however it´s difficult with this technique to amount of the stress during the compression process.In contrast to strain elastography, SWE uses an acoustic radiation force impulse created by a focused ultrasound beam, which allows measurement of the propagation speed of shear waves within the tissue to locally quantify its stiffness in kilopascals or m/s. Because the speed of sound through tissues is dependent on the "stiffness" of these tissues, a quantitative value of the stiffness can be obtained, shear wave velocity is propo...

“…In recent years, a variety of manufacturers have begun to incorporate elastography, a realtime tissue stiffness measuring technique in ultrasound equipment. In the breast, cancers tend to be stiffer than benign lesions, and elastography has also been reported to improve the specificity for the diagnosis of solid breast masses (2)(3)(4).…”
