Differential diagnosis of brain lesions by gallium scanning
The effectiveness of gallium and technetium scanning was compared in the detection of brain tumors and to evaluate whether the combined use of both radionuclides might help in the differential diagnosis of tumors versus infarcts. Seventy-seven patients were studied, 28 with brain tumors and 43 with infarcts. Twenty-eight infarction cases had positive technetium brain scans while the gallium scan was negative. An additional nine cases showed a marked disparity between the technetium and gallium accumulation with the gallium study read as equivocal. In six cases no differential was possible since the gallium uptake approached that of technetium. Of the 28 intracranial neoplasms studied, nine showed gallium uptake to be greater than technetium uptake, using visual comparison of the density ratio in lesion to calvarium as criterion. In four of these cases the lesions were detected with gallium and not with technetium. Two cases showed gallium uptake slightly less than with technetium. It is concluded that /sup 67/Ga scanning is a useful adjunct to brain scanning with /sup 99m/Tc, particularly in the early detection of certain tumors as well as the differentiation of tumor from infarct.
