Diagnostic sensitivity of imaging modalities for hepatocellular carcinoma smaller than 2 cm

Figure 2 Case No. 2: detection by gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid magnetic resonance imaging. Imaging and histological findings of the nodule in segment six. A: Ultrasonography (US) reveals an 8 mm hyperechoic nodule (arrow); B: Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid magnetic resonance imaging reveals a defect (arrow) in the hepatobiliary phase; C: The nodule is diagnosed as well-differentiated hepatocellular carcinoma by US-guided biopsy, showing cellularity more than two-fold that of the non-tumorous area.
