Elastographic versus B-mode dimensional analysis of breast tissue lesions
Résumé
The objective of elastography is to complement mammography and ultrasound to better differentiate between benign and malignant breast lesions. In this aim, strain-related criteria have been introduced, based on axial strain imaging but also shear strain imaging. In this study, size and shape of fibroadenomas and cancers between B-mode and axial strain images are compared. To quantify the size differences observed, the area of the lesions in elastograms and sonograms were determinedand the strain/B-mode area ratios computed.
