The ultrasound is also helpful to make the diagnosis of a variety of soft tissue tumors bacause of its safety, low cost, noninvasiveness and usefulness.
We analysed untrasonographic findings of 43 cases of soft tissue tumors which were histopathologically confirmed by biopsy and obtained the following results. The ultrasonography could effectively image not only the presence, size and location of
the
lesion, but also the relationship between the lesion and the adjacent structures. And this method could easily identify the consistency of the lesion, solid or cystic nature, be used to guide the percutaneous biopsy and aspiration without
exposure
to
radiation, and afford the differentiation of malignant lesion from benign one. It could also define the entities of soft tissue tumors by the nature of internal echo, margin of the lesion, internal echo homogeniety, post-acoustic enhancement, and
so on.
