Various diffusion magnetic resonance imaging techniques for pancreatic cancer

Figure 6 Images in a 52-year-old man with a focal lesion in the body and tail of the pancreas. MR imaging suggests that it is a malignancy. A: Axial T1-weighted fat-suppressed gradient-echo MR image; B: Axial T2-weighted fat-suppressed fast spin-echo MR image; C-G: Axial and coronal slab three-dimensional liver acquisition with volume acceleration dynamic contrast-enhanced; H: MRCP shows the dilated main pancreatic duct in the body and tail of pancreas; I-P: Multi-b DWI imaging (b = 0, 50, 100, 300, 500, 800, 1000 and 1500); Q and R: DTI (b = 500 and 800) using 30 diffusion gradients directions; S and T: DKI (b = 1500 and 2000) using 30 diffusion gradients directions. MR: Magnetic resonance; DWI: Diffusion weighted imaging; DKI: Diffusion kurtosis imaging; MRCP: Magnetic resonance cholangiopancreatography.
