Various diffusion magnetic resonance imaging techniques for pancreatic cancer

Figure 4 Images in a 65-year-old woman with a focal lesion in the neck of the pancreas. Magnetic resonance (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 and D: Axial slab three-dimensional liver acquisition with volume acceleration dynamic contrast-enhanced; E-L: Multi-b DWI (b = 0, 50, 100, 300, 500, 800, 1000 and 1500); M-P: Standard ADC = 1.52 × 10^-3 mm²/s, slow ADC = 1.39 × 10^-3 mm²/s, fast ADC = 63 × 10^-3 mm²/s and f = 7.2% generated by the post-processing from the multi-b DWI. DWI: Diffusion weighted imaging; ADC: Apparent diffusion coefficient.
