Multiparametric evaluation of a 64-year-old patient with rectal cancer, pre-therapy. (a) Sagittal fast spin-echo T2-weighted image (left) and sagittal diffusion-weighted image with high b-value (b = 800 s/mm2) (center) and ADC map showed a big rectal tumour with restricted diffusion. (b) Perfusion MRI-related parametric maps (transfer constant, Ktrans and return constant, kep), gadolinium concentration/time curve of the tumour evidenced increased perfusion within the tumour and a type 3 curve. (c) MR spectroscopy depicted an increased lipids peak. (d) Sagittal 18F-FDG-PET image evidenced an increased uptake of glucose in the tumour (red arrows)
