Brain edema imaging

Radiolabeled amino acids have been introduced as SPECT and PET tracers that allow a precise delineation of brain tumor in cerebral gliomas and differentiation of tumor tissue and edema. Radiolabeled amino acids are taken up by specific amino acid transporters in glioma cells [198-201]. Recently 0-(2-[ F] fluorethyl)-L-tyrosin (p FjFET) has been introduced as PET brain tumor imaging tracer [202,203].

Fig. 16.11. Neuroimaging of the case above (Fig. 16.10) showed diffuse hyperintensity on DWI of both cerebral hemispheres (white brain), affecting all components cortex, basal ganglia and white matter.
