A new device for isometric localization of nonpalpable breast lesions detected by mammography. Experience in over 100 cases

One of the main problems in localization in mammography is the changing geometry of the breast. It is seldom possible to obtain identical mammograms due to the palpation or rotational effect. The authors have developed a method which aims to satisfy the following conditions: (1) between mammography and localization the isometry must be guaranteed, (2) high accuracy, (3) additional mammographies must be limited to 2, (4) no dependence upon the model of the mammography unit, (5) minimal discomfort for the patient, (6) practicability also in smaller hospitals. The unit and method are described. (Auth.)
