Tissue doppler and strain imaging for evaluating tissue elasticity of breast lesions

Aim: Sonoelastography depicts the intrinsic elastic properties of a tissue which are characterized by the strain applied to achieve tissue deformation and the velocity at which tissue deformation occurs. The present study served to investigate whether the specificity of B-mode ultrasound (US) can be improved by combining B-mode imaging with tissue Doppler imaging (TDI) and offline analysis of tissue strain imaging (TSI). Methods: 25 with malignant and 25 with benign focal breast lesions were examined by US with a linear transducer (9MHz, Aplio, Toshiba). B-mode US views of the lesions were overlaid with color-co…
