A 41-year-old female patient with histological proven pancreatic adenocarcinoma in the head of the pancreas. The images showed the lesion with clearly demarcated hyperintensity area compared with the surrounding normal tissues on DWI images. Axial contrast-enhanced MRI image depicted a hypointense lesion in the head of the pancreas (a); Axial T2WI (b); freehand ROIs were drawn along the high signal intensity border of the tumor with obtained DWI images (b = 600 s/mm2, (c) to cover the largest possible single-slice area.
