Surveillance and diagnosis of hepatocellular carcinoma: A systematic review

Figure 2 Importance of precise late arterial phase. A: Too early arterial phase. Aorta and left hepatic artery (thin arrow) with high signal intensity, but no contrast is seen in portal vein (thick arrow). No contrast in the suspicious lesion; B: Late venous phase: washout and capsule in the lesion (but no diagnoses due to lack of hyperintensity in arterial phase due to bad technique). Note the artifact in MRI images (*); C: CT was performed in the same patient with a good late arterial phase depicting hyperattenuation of the lesion that it is now diagnostic. Contrast in left portal vein can be seen (thick arrow).
