[Local radiometry of tumors of the breast]

The authors propose a radionuclide method of diagnosis of breast tumors based on focal radiometry of 99mTc-pertechnetate accumulated in them after injection. Radiometry is done with a scanner with a pulse counter. The ratio of pulse counts accumulated in a tumor, to this indicator on the contralateral side makes it possible to determine a tumor type. This method is of diagnostic importance for tumors with a diameter less than 2 cm, their individual sections and also for lymph nodes.
