Examples of negative correlations between k 3 and v d and discordance between k 3 and TBR in parametric maps for patients 1 and 2. From left to right: pre-PET transverse CT scan; FAZA-PET TBR at 1 h for the tumour contour shown on the CT; TBR at 2 h; k 3 map; v d map. Strong negative correlations between k 3 and v d are evident. In both tumour slices, there are regions where v d is well-below unity and variations in k 3 and TBR are discordant
