Answer

As mentioned, ultrasonography is highly operator dependent. Therefore, its efficacy depends on obtaining images that are of high technical quality, on interpreting those images correctly, and on clearly reporting the results.

Baker et al and Rahbar et al demonstrated that observer variability varies considerably in the description and assessment of solid masses demonstrated on sonograms. [39, 40] More uniform and more clearly understandable examination reports are needed to improve patient care and to facilitate research in the use of breast US.
