Figure 2: A low axillary lymph node is the most RGD-K5 avid lesion in Subject-1, shown on the top row. The baseline RGD-K5 SUVmax measured before treatment is 10.8, and the value is decreased to 3.5 after receiving 4 doses of bevacizumab. The size measured on CT is 1.5×1.1 cm on the baseline scan, and 1.0×0.6 cm on the follow-up scan. The FDG uptake is much lower. The pre-treatment FDG SUVmax is 1.03, and is decreased slightly to 0.9 after 4 doses of bevacizumab.
