Figure 1From: Hypoxia, blood flow and metabolism in squamous-cell carcinoma of the head and neck: correlations between multiple immunohistochemical parameters and PET Relationship between PET findings and immunohistochemistry. Association between the expression of p53 (A) and the amount of apoptotic cells (B) with [18F]FDG SUV (●, lower SUV; ○, higher SUV). The amount of apoptotic cells displayed an association with the metabolically active tumor volume (C) and a trend toward an association in the expression of Ki-67 was also seen with the metabolically active tumor volume (D) (●, values less than or equal to the median value; ○, values greater than the median value). In E, the association between VEGF expression and [18F]FDG SUV is illustrated as ●, weak expression; ○, intense expression.Back to article page
