Enhancement patterns of pancreatic adenocarcinoma on conventional dynamic multi-detector row CT: Correlation with angiogenesis and fibrosis

Figure 3 Well-differentiated tubular adenocarcinoma in a 44-year-old man. A: Transverse dynamic CT images; B: Time-attenuation curve. Dynamic CT scans showing low enhancement in the arterial phase; C: Photomicrograph showing immunoreactivity to VEGF, which is depicted as brown cytoplasm. The score was 1 (extremely weak) (Anti-VEGF stain; original magnification, × 400); D: Photomicrograph showing few microvessels and depicting vessel walls, which appear brown (Anti-CD34 stain; original magnification, × 200).
