Abdominal applications of diffusion-weighted magnetic resonance imaging: Where do we stand

Figure 5 Focal nodular hyperplasia. A: Enhanced arterial phase; B: Venous phase T1-weighted gradient recalled-echo; C: Diffusion-weighted image; D: Apparent diffusion coefficient map (ADC). An arterial enhancing lesion which becomes isointense to slightly hyperintense to liver on venous phase and shows impeded diffusion with ADC of 1.3 × 10^-3 mm²/s.
