A 50-year-old man with pancreatic head cancer. Baseline axial T2 single-shot fast spin echo (ssFSE) pre-treatment MRI (a) demonstrates the primary tumour (open black arrow) and L2 metastasis (asterisk). The patient underwent Whipple’s procedure and external beam radiotherapy (RT) for L2 metastasis (30Gy over ten fractions). Follow-up MRI was performed 9 months after treatment. Coronal (b), sagittal (c) T2 ssFSE and axial fat suppressed T2 ssFSE (d) demonstrate increased T2 signal intensity in the medial upper pole renal cortices (open white arrows in b and d) consistent with acute radiation nephropathy. Note marrow replacement in the spine and partially treated L2 metastasis (asterisk) in c. Areas of radiation nephropathy demonstrate restricted diffusion in the medial upper poles (solid white arrows) on axial fat suppressed diffusion weighted echo planar (EPI) images (B50, B400 and B800—left to right in e). There is corresponding low signal intensity (black arrow) on ADC map (f)
