In addition to MR imaging, PET imaging of O-(2-[18F]Fluorethyl)-L-Tyrosine (FET) uptake provides information on brain tumour extent and metabolic activity. Similarly, MRS has been shown be value for distinguishing high- from low-grade gliomas. Based 2D spatially resolved MRSI, an overlap between 18FET the choline/N-acetyl-aspartate (Cho/NAA) ratio more than 75 % reported.
