From: pO polarography, contrast enhanced color duplex sonography (CDS), [18F] fluoromisonidazole and [18F] fluorodeoxyglucose positron emission tomography: validated methods for the evaluation of therapy-relevant tumor oxygenation or only bricks in the puzzle of tumor hypoxia?

Figure 2

From left to right: transaxial FDG PET-, transaxial FMISO PET-, CDS- and transaxial CT scans in two different patients. A:with a normoxic tumor (pO2 ≤ 2.5 mmHg = 13.0%, pO2 ≤ 5.0 mmHg = 15.1%, pO2 ≤ 10.0 mmHg = 17.0%, median pO2 = 36.2 mmHg, mean pO2 = 41.1 mmHg; CPD = 12.05%; FDGSUVmax = 17.84, FDGSUVmean = 14.80; FMISOT/M = 1.31, FMISOT/B = 1.07). B:with a hypoxic tumorB (pO2 ≤ 2.5 mmHg = 37.7%, pO2 ≤ 5.0 mmHg = 48.8%, pO2 ≤ 10.0 mmHg = 58.1%, median pO2 = 5.5 mmHg, mean pO2 = 17.7 mmHg; CPD = 2.71%; FDGSUVmax = 9.34, FDGSUVmean = 8.00; FMISOT/M = 1.60, FMISOT/B = 0.88). 1/2 = distance measurements for the guidance of the polarographic needle electrode
