[What is the reliability of conventional ultrasound mammography and color coded ultrasound in diagnosis of breast tumors?].
To establish the diagnostic relevance of sonographic blood supply measurement for tumor's nature evaluation, 192 women with suspect unilateral breast findings were examined on the preoperative day with color coded sonography (MEM color technique). A combination of evaluation in B-scan and color mode resulted in a sensitivity of approx. 96% in cases of malignant tumors (121 histological findings of breast cancer). Specificity in the 71 patients with a histologically benign diagnosis was of over 90%. Despite an essential improvement in dignity diagnosis, histologic proof is, however, necessary, even in cases of benign findings at the diagnosis. Since a 100% certainty in the differentiation of benign and malignant tumors will never be achieved with ultrasound techniques, biopsy specimen will have to be taken. Thus additional measurements of tumor blood flow seems of no clear advantage for the patient. In our opinion, the essential contribution of blood flow diagnosis of malignant tumors lies rather in the evaluation of tumor prognosis, since the differences in the blood supply of malignant growths are indicators for their biological behavior.
