Figure 2 CT images of cases in Group A, B, C. Case A, Male, 67 years old, giant hepatocellular carcinoma, BMI 26.18 kg/m2. Figures A1–A4 are 40keV, 70keV, 80keV and 90keV images of cases in Group A at portal venous phase, respectively. Case B, Male, 79 years old, nodular cell hepatocellular carcinoma, BMI 18.90 kg/m2. Figures B1–B4 are 40keV, 70keV, 100keV and 110keV images of cases in Group B at portal venous phase, respectively. Case C, Male, 44 years old, nodular hepatocellular carcinoma, BMI 22.84 kg/m2. Figures C1–C4 are 40keV, 70keV, 90keV and 100keV images of cases in Group C at portal venous phase, respectively. With the increase of keV, the CT value, image noise, CNR, and SNR gradually decrease. (P<0.001). All the images in Figure were downloaded from GE AW8.0.
