The mean age of the patients was 59 years (range, 41 - 85 years). The final histopathological analysis revealed six malignant breast lesions, four of which were presented as a mass and two as an architectural distortion. There was no significant difference between digital breast tomosynthesis and SV in mass characterization, and both digital breast tomosynthesis and SV showed high sensitivity and negative predictive value (NPV) for the detection of breast carcinoma. Nevertheless, SV showed greater overall specificity in comparison to digital breast tomosynthesis (84% to 50%) as shown in Fig 1.
Even though in the case of a negative SV finding, the overlap of negative SV and breast ultrasound findings was 100%, breast ultrasound has shown greater specificity than SV for the detection of breast cancer (87% vs 77%) at the same level of sensitivity and negative predictive value as shown in Fig 2.
In 29% (18/62) of the patient, the availability of SV after digital breast tomosynthesis eliminated the need for ultrasound as a part of the diagnostic process.
