Effects of ROI Placement on PET-Based Assessment of Tumor Response to Therapy
Figure 2
The uptake profile from Figure 1 normalized to Pre-Tx maximum SUV. The distribution of uptake within the tumour has changed during the therapy such that the maximum uptake point along the profile in Pre-Tx corresponds to a local minimum uptake point in the Intra-Tx. The maximum uptake point along the profile in Intra-Tx is now in a different location of the tumour.
