Evaluation of Malignancy in Ring Enhancing Brain Lesions on CT by Thallium-201 SPECT
JNNP 63:569-574, Kallen,K.,et al, 1997
See this aricle in Pubmed

Article Abstract
Fourteen high grade gliomas,three low grade gliomas,and four abscesses were found.Uptake was higher in the highly malignant glioma group(median thallium index(TI)=2.1),than in the low grade glioma group(medial T1=1.6). Overlapping indices were found between high and low malignant cystic gliomas as well as between either one of the glioma groups and the infectious lesions,and there were no significant differences between groups.It is concluded that high 201T1 uptake in enhancing cystic lesions is an indicator of highly malignant glioma.However,the differentiation between the high malignant gliomas and abscesses or low malignant gliomas by 201TL SPECT is only partial with an overlap between these groups.
