Compression-free biplanar radiography of the breast specimen with a specimen device

Purpose: To develop a device for specimen radiography of impalpable breast lesions with microcalcifications in order to perform compression-free radiography in two planes and to document the original orientation of the specimen on the radiographic film. Materials and Methods: A curved plate with its radius equal to the film-focus-distance enables specimen radiography without compression and with minimizing artifacts induced by beam divergency. Adjustable markers can document the topographic orientation of the specimen on the radiographic film. Results: The presented specimen device for biplanar radiography avoids interfering compression artifacts for both radiologist and pathologist. Documenting the original topographic orientation of the specimen on the film helps to guide the surgeon in cases requiring further resection. Discussion: Biplanar specimen radiography without compression of the specimen measures the distance of microcalcifications to the margin of the resected tissue more accurately and thus provides a better basis for planning any necessary additional resection.
