To determinate the diagnostic performance of sonographic elastography for the differentiation of benign from malignant breast masses.

MATERIAL AND METHODS: Sonographic elasticity images of 86 nonpalpable breast masses (30 benign and 56 malignant masses). After subtraction of B-mode images from color elasticity images. Elasticity images were also reviewed and were assigned a score on a five-point scale. Lesion dimensions were measured by using calipers on recorded B-mode US images and elastography postacquisition images. Two quantitative elasticity values were extracted, the first corresponding to the elasticity value of the lesion and the second to the elasticity value of normal tissue. Distinguishing benign from...

Elastography is a very helpful technique that adds value to the sonographic examination by enabling you to evaluate the stiffness of tissue. Studies have shown that a combination of ultrasound elastography and sonography had the best results in detecting cancer and potentially could reduce unnecessary biopsies. •“Quantifying manual palpation” •Elasticity of lesion –Stiffer a lesion the more likely it is malignant –Except cysts! •Quantification –Graphs vs colour map –Fat:Lesion ratio•>10 (more likely malignant) •Application: –Distinguishing benign from malignant –Reassurance on B Mode appearance •Similar to...

Elastography has the potential to be useful in the evaluation of areas of shadowing on the sonogram. It also may be helpful in the distinction of benign from nonpalpable malignant masses.
