Figure 2: A 68-year-old patient with liposarcoma of the oropharynx. A maximum intensity projection (MIP) of the PET shows increased FDG uptake in the tumour ((f), arrow) as compared to the PET six months before (c). The short tau inversion recovery (STIR) images ((a) and (d)) and the corresponding fused PET/MR images ((d) and (e)) show no change in tumour size over six months.
