Likewise, there was no correlation between the grayscale images of the mammary tissue by qualitative elastography. A difference was found in the deformity of the mammary masses between the malignant and benign groups (P = 0 · 002). Using quantitative elastography, the mean values of shear velocity were 3 · 33 m/s for malignant tumours and 1 · 28 m/s for benign tissue (P < 0 · 0001).</p> </sec> <sec id="jsap12256-sec-0004" sec-type="section"> <title>CLINICAL SIGNIFICANCE</title> <p id="jsap12256-para-0004">The use of acoustic radiation force impulse elastography may help to differentiate between malignant and benign mammary neoplasms.</p> </sec> </abstract>
