MRI images of histological proven pancreatic cancer in 56-year-old female patient with a lower ADC (1.08 × 10− 3 mm2/s), orally taken S-1 and a lower pre-treatment CA19–9 level (339.9 U/ml). The OS was 522 days. Axial precontrast T1WI (a); Axial T2WI (b); Axial contrast-enhanced T1WI (c); DWI image (b = 600 s/mm2, (d)); freehand ROIs were drawn along the high signal intensity border of the tumor with obtained DWI images (b = 600 s/mm2, (e)) to cover the largest possible single-slice area.
