Figure 5. Final MRI and MET PET imaging.
A, B: coronal and axial MRI images. The most recent MRI findings indicated no lesions in the right paranasal cavity; however, the space-occupying lesion (SOL) in the cranial cavity showed increased contrast enhancement in some areas, and the edematous changes in the surrounding brain parenchyma had worsened.
C: MET PET imaging. Mean standardized uptake (SUVmean) of 1.39 in the tumor and 1.07 in normal brain tissue was observed.
MET: 11C-methionine; PET: positron emission tomography
