[Sonography in therapy-oriented diagnosis and after-care of primary bone and soft tissue tumors].

Based on the results of 150 patients with primary tumors or the suspicion of malignant lesions of the locomotor system the perspectives and limits of the sonographic diagnosis under the therapeutic aspects of interdisciplinary oncologic cooperation is demonstrated. As the ideal adjunct to conventional roentgenograms, ultrasound is the first-line imaging procedure in the fields of primary diagnosis, follow-up, post-therapeutic care as well as tumor exclusion for methodic, patient-related and economic/logistic reasons. Its consequent application will markedly reduce the number of more invasive and expensive methods.
