Comparing PET/MRI with PET/CT for Pretreatment Staging of Gastric Cancer

Figure 6

A 75-year-old man with gastric carcinoma diagnosed as liver metastasis proven by clinical information of follow-up. (a) Axial CT image shows suspicious mild low density in segment VII of the liver (arrow). (b, d) On fusion PET/MRI and PET/CT image, the right liver node shows FDG uptake with an SUVmax of 4.3 (arrow). (c) On the T2-weighted axial image, a moderate high signal intensity node is seen (arrow). (e) On the PET image, an obviously avid FDG uptake was observed (arrow). (f) This lesion shows high signal intensity on diffusion-weighted image with a -value of 800 (arrow).
