Figure 4. Case 4 — A: Gd contrast-enhanced T1-weighted image

B: FLAIR (fluid-attenuated inversion recovery) image

C: [¹¹C]methionine positron emission tomography (MET-PET)

D: anti- [¹⁸F]FACBC positron emission tomography (FACBC-PET)

A 57-year-old man who had a small round-shaped mass without enhancement in the right frontal lobe in Gd T1-weighted image, which was diagnosed with oligodendroglioma, grade II, IDH mutant, 1p/19q co-deletion. This case showed 1p19q co-deletion. Both PET tracers were detected in a high signal lesion of FLAIR image, and it was easy to detect the border between tumor and cortex. FACBC-PET showed clearer contrast of abnormal lesion than MET-PET.
