Fig. 5A. —70-year-old man with cirrhosis due to chronic type C viral hepatitis
and moderately differentiated 7.4-cm hepatocellular carcinoma showing mild
vascular endothelial growth factor (VEGF) expression, moderate hypointensity
on in-phase T1-weighted, heterogeneous mild hyperintensity on T2-weighted, and
heterogeneous mild enhancement on hepatic arterial dominant phase images.
Child-Pugh grade was B. Schematic shows electrophoretic bands and
corresponding histograms in this patient. VEGF solution (1.25 mg/mL) was used
for calibration. Area of histogram was 723 pixels for calibration band, 1,559
pixels for hepatocellular carcinoma band (HCC), and 1,455 pixels for
surrounding liver band. VEGF expression index (VEGFIND) was 2.16 in
hepatocellular carcinoma and 2.01 in surrounding liver, giving
VEGFIND difference of 0.15.
