[Spatial visualisation of an intraductal mamma carcinoma (author's transl)]

Layer radiology was performed in the roentgenographic visualisation of a mainly intraductal (comedo) carcinoma showing a characteristic triangular microcalcified group in the x-ray film. A three-dimensional model was constructed on the basis of this stratified visualisation. It was found to be wedge-shaped, as was to be expected on account of the anatomical conditions, proving that the "triangular principle" can be considered as correct.
