Figure 3
Percent changes of tumor volume and selected PET parameters during and immediately after radiotherapy. (a) Tumor volume. (b) Standard uptake value (SUV). (c) Retention index (RI). (d) Sensitivity factor (SF). A solid line represents tumors with local failure (LF); dashed line represents tumors with local control (LC). Points are shown as means with error bars indicating SE and only positive SE are shown for clarity.
