Banoxantrone (BN) induces modification of tumor hypoxia in Calu6 xenografts. A, TMR of [18F] FAZA uptake is increased from baseline at day 1 and 3 in control tumors (Cn; white bars) but was reduced in drug-treated tumors. B, Example, [18F] FAZA PET images with greatest hypoxia represented by orange and red. C, Tumor MRI hypoxic fraction showed similar relative reduction at day 1 and 3, relative to control tumors. D, Example segmented MRI images showing hypoxic (blue), normoxic (yellow), and necrotic (gray) tumor. E, Lower percentage of pimonidazole staining was detected in drug-treated tumors at day 3, compared to controls. F, Example pimonidazole adduct formation images (×40 magnification).
