Clinical Applications of FDG PET and PET/CT in Head and Neck Cancer
Figure 4
Patient with a squamous cell carcinoma of the right mandible (arrows). (a) The [18F]Galacto-RGD PET shows heterogeneous tracer uptake, which can also be clearly delineated in (b) the image fusion with the corresponding MRI scan. (c) shows the tumour volume in red as defined by MRI. By applying a threshold of SUV 3 and only using pixels with SUVs above this threshold, (d) a subvolume with more intense vß3 expression can be defined which is shown in the 3D reconstruction (blue line in (c), blue area in (d)).
