Correlation of CT enhancement, tumor angiogenesis and pathologic grading of pancreatic carcinoma

Figure 2 A 52-year-old man with moderately-differentiated pancreatic head carcinoma. A: Pancreatic-phase helical CT enhancement imaging 35 s after administration of contrast agent revealed that CT enhancement of mass in pancreatic head was slightly lower than that of normal pancreatic tissues. Scarce blood vessel area appeared in the central region of the mass; B: Showing immunohistochemical staining of anti-CD34 antibody (200 ×). CD34-positive cells were counted as microvessels (tan color), moderate MVDs in hot spot area of the neoplastic cells in moderately-differentiated pancreatic carcinoma.
