Differentiation of hepatocellular carcinoma from its various mimickers in liver magnetic resonance imaging: What are the tips when using hepatocyte-specific agents?

Figure 4 Dysplastic nodule in the same patient as Figure 1. A: precontrast T1-weighted image shows a hyperintense nodule in segment 8, suggesting high contents of iron or copper; B: Hepatic arterial phase of gadoxetic acid-enhanced MRI shows isointensity of the tumor; C, D: transitional and hepatobiliary phases show hypointensity of the tumor relative to the liver parenchyma; E, F: T2-weighted image and diffusion weighted image (b = 800) show isointensity of the tumor.
