Abstract:An increased amino acid metabolism is characteristic for many brain malignancies. Combined positron emission and computed tomography (PET/CT) with radiolabeled amino acids is often used in recognizing the tumor nature of the structural brain lesion detected on MRI. On 11C-methionine PET/CT a hallmark of a brain tumor is an increased amino acid uptake, topographically coinciding with a structural lesion on MRI. However, high 11C-methionine uptake in the brain lesion is not tumor specific and could be seen in a … Show more
