TLDR
For assessing breast lesions, US elastography with the proposed imaging classification, which was simple compared with that of the Breast Imaging Recording and Data System classification, had almost the same diagnostic performance as conventional US.Abstract:
Purpose: To evaluate the diagnostic performance of real-time freehand elastography by using the extended combined autocorrelation method (CAM) to differentiate benign from malignant breast lesions, with pathologic diagnosis as the reference standard. Materials and Methods: This study was approved by the University of Tsukuba Human Subjects Institutional Review Board; all patients gave informed consent. Conventional ultrasonography (US) and real-time US elastography with CAM were performed in 111 women (mean age, 49.4 years; age range, 27–91 years) who had breast lesions (59 benign, 52 malignant). Elasticity images were assigned an elasticity score according to the degree and distribution of strain induced by light compression. The area under the curve and cutoff point, both of which were obtained by using a receiver operating characteristic curve analysis, were used to assess diagnostic performance. Mean scores were examined by using a Student t test. Sensitivity, specificity, and accuracy were compared b...read more

Ultrasound elastography: Principles and techniques
TL;DR: The principles of elastographic techniques are introduced and a technical summary for the main elastography techniques are given: from quasi-static methods that require a static compression of the tissue to dynamic methods that uses the propagation of mechanical waves in the body.

Elastic Moduli of Breast and Prostate Tissues under Compression
TL;DR: To evaluate the dynamic range of tissue imaged by elastography, the mechanical behavior of breast and prostate tissue samples subject to compression loading has been investigated and the data show that breast fat tissue has a constant modulus over the strain range tested while the other tissues have a modulus that is dependent on the strain level.

Elastography of breast lesions: initial clinical results.
TL;DR: Elastography has the potential to be useful in the evaluation of areas of shadowing on the sonogram and also may be helpful in the distinction of benign from malignant masses.

In vivo real-time freehand palpation imaging
TL;DR: The preliminary data suggest that the strain image sequences for various breast pathologies are unique, and that a comparison of the lesion area measured in B-mode vs. strain images appears to be a sensitive criterion for separating invasive ductal carcinoma from cyst and fibroadenoma.

Real time tissue elasticity imaging using the combined autocorrelation method.
TL;DR: A more useful technique for imaging tissue elasticity, which is called the combined autocorrelation (CA) method, has the advantages of producing strain images of high quality with real-time processing and being applicable to large displacements.

Freehand ultrasound elastography of breast lesions: clinical results.
TL;DR: A freehand method for ultrasound elastography, which can be applied during a routine sonographic examination with off-line calculation of strain images (elastograms), and a freehand applicator, which guarantees a homogeneous axial compression regardless of the experience of the examiner is developed.
