Figure 4From: Significant impact of different oxygen breathing conditions on noninvasive in vivo tumor-hypoxia imaging using [18F]-fluoro-azomycinarabino-furanoside ([18F]FAZA)[18F]FAZA tumor and muscle clearance in both tumor models. [18F]FAZA clearance is displayed in both animal models (relative to 1 h after injection) with a higher muscle clearance (** p < 0.01; PyV-mT C57/BL6, n = 9; CT26 colon carcinoma-bearing BALB/c, n = 10).Back to article page
