Methyl-L-11C-methionine PET as a diagnostic marker for malignant progression in patients with glioma.
UNLABELLED Methyl-L-(11)C-methionine ((11)C-MET) PET has been shown to detect brain tumors with a high sensitivity and specificity. In this study, we investigated the potential of (11)C-MET PET to noninvasively detect tumor progression in patients with gliomas. Moreover, we analyzed the relationship between changes in (11)C-MET uptake on PET and changes in various molecular immunohistochemical ...
متن کاملTumor uptake studies of S-adenosyl-L-[methyl-11C]methionine and L-[methyl-11C]methionine.
Tumor accumulation of S-adenosyl-L-[methyl-11C]methionine ([11C]SAM) was investigated in mice bearing mammary carcinoma (FM3A) and in rats bearing ascitic hepatoma (AH109A). After injection of [11C]SAM the blood clearance of 11C radioactivity was rapid. The 11C level was relatively high in both tumors. The uptake ratios of tumor to organ increased with time in several organs, especially in brai...
متن کاملDiagnosis of Brain Tumors Using Amino Acid Transport PET Imaging With 18F- Fluciclovine: A Comparison Study With L-Methyl-11C-Methionine PET Imaging
Objective(s): 18F-fluciclovine (trans-1-amino-3-[18F] fluorocyclobutanecarboxylic acid, [FACBC]) is an artificial amino acid radiotracer used for positron emission tomography (PET) studies, which is metabolically stable in vivo and has a long half-life. It has already been shown that FACBC-PET is useful for glioma imaging. However, there have been no reports evaluating the efficiency of FACBC-P...
متن کاملClinical positron emission tomography for brain tumors: comparison of fludeoxyglucose F 18 and L-methyl-11C-methionine.
PURPOSE To evaluate the differences between fludeoxyglucose F 18 (FDG) and L-methyl-11C-methionine (11C-methionine) as tracers for positron emission tomography (PET) in the evaluation of brain tumors. METHODS We analyzed 10 patients with histologically verified cerebral glioma or meningioma and 1 patient with a neuroradiologic diagnosis of low-grade glioma by using FDG, 11C-methionine, and PE...
متن کاملA novel PET index, 18F-FDG-11C-methionine uptake decoupling score, reflects glioma cell infiltration.
UNLABELLED The linear correlation between (11)C-methionine PET and tumor cell density is not well conserved at the tumor border in glioma. A novel imaging analysis method, voxelwise (18)F-FDG-(11)C-methionine PET decoupling analysis (decoupling score), was evaluated to determine whether it could be used to quantitatively assess glioma cell infiltration in MRI-nonenhancing T2 hyperintense lesion...
