Evaluation of volume and shape of breasts: comparison between traditional and three-dimensional techniques

There have been many attempts to evaluate the shape, volume, and contour of breasts both before and after operation. To evaluate and compare results objectively in a reproducible, low-cost way is difficult. The aim of this study was to compare three-dimensional techniques with traditional methods in evaluating the volume and shape of breasts. Twelve patients with breast cancer were evaluated, 6 patients preoperatively and 6 patients postoperatively, using plastic cups, thermoplastic casts, magnetic resonance imaging (MRI), and three-dimensional imaging techniques. Thermoplastic casts and plastic cups measured better accordance with the volume of the operated breast than either the three-dimensional technique or MRI, which resulted in significantly higher values. The three-dimensional technique offered a new possibility to evaluate the shape of breasts objectively.
