Internal echo histogram examination has a role in distinguishing malignant tumors from benign masses in the breast
1Department of Surgery II, Nagasaki University School of Medicine, 1-7-1 Sakamoto, Nagasaki, Japan.
Abstract:
We analyzed the histograms of reflecting ultrasound (US) from the internal areas of the masses of 50 lesions in the breast. The central average of gravity and the ratio between lower and higher width in the histograms were compared as the parameters. Statistical significance were found in both parameters between malignant tumors and benign masses (P<.001, P<.01). Therefore, analysis of histograms based on reflecting US was useful in making differential diagnoses of malignant tumors and benign masses in the breast.
