[Study of gallium-67 citrate distribution in rat tumors].

In rats with transplantable tumors of different histological structure the authors have studied the dynamics of gallium-67 citrate distribution in tumors, adjacent tissues and blood. It has been found that gallium-67 is able to be accumulated in increased amounts in all tumors irrespective of their histological type. Tumor image in scannograms was mostly distinct on the 2--3d day after injection of gallium-67 citrate, when there was the greatest difference in accumulation of the isotope in the tumor and surrounding "intact" tissues.
