In this study ultrasonic findings of the breast were analyzed, and further examined by using the quantification classification II to improve its diagnositic ability. Among 250 cases undergoing echography of the breast using a 10 MHZ terminal from July 1990 to February 1991, 90 cases including 44 of breast cancer which were able to be histologically diagnosed were subjected. Echographic findings were classified by 7 factors such as shape and verge of the tumor, and analyzed by the quantification classification II in order to distinguish breast cancer from other diseases. In addition, these obtained category scores were applied to calculate for newly diagnosed 34 cases of breast caner. As a result, the eccentric correlation coeficience was largest for verge followed by posterior echo, which might be important factors for differential diagnosis of breast cancer from others. Such findings as irregular belt-like border and weakened posterior echo had a large category score, especially being indicative of breast cancer. The correct diagnosis rate was 86% for breast cancers. It was 85%, when calculated by applying the category scores to the recently diagnosed 34 cases of breast cancer. By making the most use of the category score calculated, more objective diagnostic avility can be achieved. |
