The detection of malignant or dysplastic cells in a tissue sample, by treating the sample with a solution containing radioactive gallium and relying upon the greater take-up of the gallium by the malignant or dysplastic cells relative to normal cells to provide a detectable signal of malignancy, is improved by including non-radioactive preemptive species in the solution to pre-empt potential gallium binding sites in protein molecules of normal cells. The pre-emptive species may be one or more of scandium, indium or yttrium. |
