Brain Tumor Imaging by Positron Emission Computed Tomography Using 11C-Labeled Amino Acids

Abstract
We report our preliminary clinical results on positron emission tomography of human cerebral tumors with 11C-tagged amino acids. Carbon-11-DL-valine and 11C-DL-tryptophan were used for imaging the tumors. Some attempts at quantitation of the uptake were also carried out. The implications of these observations are discussed. © Lippincott-Raven Publishers.
