Is mammography useful in Paget's disease of the breast?
Mammogram is of limited value in management of Paget's disease of the breast for women without breast palpable mass; it can not predict the site of malignancy, nor the invasive component.
An activity ratio of 3 between the perfusion and ventilation scan was not reached in about 25% of the 286 V/P studies (in around 8% the P/V ratio was<2), so that V/P studies were performed inadequately in a considerable number of procedures. Controlling the count rate increase during the perfusion tracer application (e. g. by handheld monitor) is therefore essential to avoid insufficient data.
