From: Apparent diffusion coefficient of pancreatic adenocarcinoma: is there any congruity with tumor resectability?

A 55-year-old male patient comes by epigastric pain and discomfort. ac Axial and coronal T2 fat saturation sequence showed diffusely enlarged swollen pancreas (head, body, and tail) with heterogeneous signals and relatively preserved peri-pancreatic fat planes. The pancreatic vessels are totally encased inside the lesion. d1d3 DWI at multiple b values (0, 500, and 1000 s/mm2) demonstrates the increase of degree of lesion restriction by the increased b value denoting the malignant nature of the lesion apart from the facilitated cystic degenerated part of the lesion in which the signal was progressively reduced (colored arrow head). e, f ADC map of the pancreas showed low signal of the lesion and the measured ROI reflected the low ADC value (0.9–1.0 × 10−3 mm2/s). Also, the mesenteric vessels are noted near totally encased within the lesion (yellow arrow at d2 and e) (non-resectable lesion)
