In the early stages, the USG appearance may be normal, even though lumps may be palpable on clinical examination. Although it may be impossible to distinguish all benign from all malignant solid breast nodules using USG criteria, a reasonable goal for breast USG is to identify a subgroup of solid nodules that has such a low risk of being malignant that the option of short-interval follow-up can be offered as a viable alternative to biopsy.
Stavros thoroughly explains the physics of breast ultrasound and the special probes and other equipment needed to produce high-resolution images of breast tissue.
The book explains every aspect of the examination in detail-from equipment selection and examining techniques, to correlations between sonographic and mammographic findings, to precise characterization of sonographic abnormalities.

It was initially believed that color Doppler scanning would add to the specificity of USG examination, but this has not proven to be very efficacious; however, in certain situations it does help resolve the issue, particularly when there is significant vascularity present within highly cellular types of malignancies[ 17 ] [ Figure 10 ].
