Scientists can form more specific images of brain tumors with the help of radiolabeled amino acids. In the current issue of Deutsches Ärzteblatt International, Karl-Josef Langen of the Jülich Research Center and his coauthors describe the current state of knowledge in this nuclear medical diagnostic technique.

Cerebral gliomas are one of the commonest types of brain tumor. The current procedure of first choice for their diagnosis is magnetic resonance imaging. However, it is very often difficult to distinguish other non-specific changes in the brain from tumor tissue. Nuclear medical diagnosis with radiolabeled amino acids allows more precise imaging, as specific transporters in the gliomas enhance the uptake of amino acids. Several studies have confirmed that more reliable images are formed. This is advantageous in planning therapy. However, the two currently approved amino acids have not yet been approved as drugs and may only be used for research purposes.
