Tumor angiogenesis and dynamic CT in colorectal carcinoma: Radiologic-pathologic correlation

Figure 1 Rectal carcinoma. A: Target plane of CT perfusion indicates invasive nodule (arrow) and ROI (white round region); B: Corresponding section of specimen shows invasive nodule (five corner star) and examined area (white round region).

Figure 2 High microvessel density, stained by CD34 (magnification, ×100).

Figure 3 Low microvessel density with high PF. A: many large vessels with low microvessel density (magnification, ×100); B: Perfusion image shows obvious enhancement of colon lesion with high PF (44.4 mL/min/100 g).

Figure 4 mean±SD for PF for each Dukes’ stage.
