OBJECTIVE We sought to evaluate diffractive ultrasound (US) in the characterization of solid breast masses. METHODS Forty-eight patients with solid breast masses (24 malignant and 24 benign) observed at conventional US underwent targeted diffractive US before needle biopsy or surgery. The process of locating the lesion was performed with knowledge of the mammography and conventional US. On diffractive US, imaging features, including shape, brightness, echotexture, margin, and boundary echo were analyzed and odds ratio (OR) were calculated to show how the risk of malignancy was altered by the presence of a given finding. RESULTS Of the 48 solid breast masses seen on conventional US, 46 (96%) were seen at diffractive US. Diffractive US features suggestive of malignancy were irregular shape (OR 11.5), sono-opacity (OR 204), spiculated margin (OR 17.0), and absent boundary echo (OR 11.5) or thick rim (OR 5.5), whereas those of benignancy were round shape (OR 0.03), sonotransmission (OR 0.07) or isodensity (OR 0.01), well-defined margin (OR 0.03), and thin capsule (OR 0.03; P < 0.05). CONCLUSIONS The finding of a sono-opaque mass on diffractive US was highly sensitive for malignancy. Further improvement of diffractive US equipment is needed to increase image quality and to permit inclusion of the axillary tail and deep portions of the breast.

D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
