The authors examined 50 patients with cerebral
glioma
with use of positron emission tomography (PET) and L-[methyl]-[11C]methionine to assess the grade of malignancy and the extent of cerebral
glioma
.
Carbon-11 methionine
was highly accumulated in the lesion in 31 of 32 patients with high-grade
glioma
and 11 of 18 patients with low-grade
glioma
. The rate of uptake of C-11 methionine in high-grade
glioma
was significantly higher than in low-grade
glioma
(P < .001). However, in individual cases it was difficult to evaluate the grade of malignancy only from the degree of C-11 methionine accumulation. In most cases, the area of increased accumulation of C-11 methionine did not correspond to the abnormalities seen at computed tomography (CT). Surgical intervention confirmed that methionine PET delineated the extent of cerebral
glioma
more clearly than did CT. The authors concluded that methionine PET has greater utility in assessing the extent rather than the grade of malignancy of cerebral
glioma
.
