Axial T1-weighted MR image before contrast a T1-weighted MR image after injection of gadolinium without fat saturation b and with fat saturation c in a patient with diffuse thickening of the neopharynx (radial free flap reconstruction) after total laryngectomy for larynx cancer. DW-MRI shows hyperintense signal (arrow) in the b800 image d with corresponding low signal in the ADC map e indicating tumour recurrence. The PET-CT image f showed intense uptake of glucose (see also Fig. 10) over a long segment due to which it was interpreted as inflammation
