Abstract

Six patients with malignant lymphoma of the brain underwent 67Ga and 201Tl brain SPECT. For the quantitative analysis, count ratios of a lesion to the normal brain (L/N) were calculated. In 201Tl SPECT studies, an L/N ratios ranged from 2.3 to 3.2, with a mean of 2.9 ± 0.4. In 67Ga SPECT studies, an L/N ratios ranged from 4.4 to 6.6 with a mean of 5.7 ± 0.8. 67Ga SPECT showed much more intense tracer uptake than 201Tl SPECT and the degree of 67Ga accumulation seems to be in proportion to the viability of malignant lymphoma. We came to the conclusion that quantitative 67Ga SPECT appears to be useful in detecting and managing malignant lymphoma in the brain.
