ABSTRACT
Objective To evaluate the clinical value of full-field digital mammography three-dimensional (3D) positioning system for localization and excision of nonpalpable breast lesions.Methods 106 patients with nonpalpable breast lesions and underwent preoperative localization were analyzed retrospectively.They underwent wire-localization operation guided by mammography 3D positioning system (GE Senogrphe DS).The depth of wire insertion was calculated manually and automatically.Combined with the manual measurement, systematic measurement, skin elasticity and breast parenchyma structure, the positioning wire was placed.Then, the clinical resection was performed according to the wire localization.Results The localization accuracy of mammography 3D positioning system was 100%.11 patients appearedsyncope.With the rest, psychological comfort and fluid infusion, patients recovered quickly.Conclusion Full-field digital mammography 3D positioning system can improve the accuracy of clinical resection of nonpalpable breast lesion.
