Digital Mammography: Preliminary Demonstration of Clinical Feasibility.
Abstract
Our objective was to assess the clinical feasibility of digital mammography using a slot scanner system and to make comparisons to conventional film-screen mammograms performed on the same patients. Of 59 patients recruited between 31 October 1996 and 30 September 1997 47 had successfully completed studies using both modalities. Three of these had screening exams and 44 had diagnostic exams. Sixteen had their digital exam before their film-screen study; 31 had the opposite sequence. Interpretative decisions using the BI-RADS system were made for study purposes after each modality. In only one patient did the availability of the second modality result in a change in management. In this case, spot compression magnification views, (unavailable with the digital unit), of a region of palpable abnormality revealed nodular densities that on ultrasound were simple cysts. Only one patient had cancer; this was evident using both modalities. Delay in-installation of the unit and subsequent malfunctions made it impossible to conduct the study in the fashion originally planned. Nevertheless, a number of observations were made, several of which have led to modifications of the unit that are likely to enhance its performance in the clinical setting.
