MicroPET imaging of NCI-H1299-CDDP-bearing model with 68Ga-NOTA-Nb109. a Representative PET images of NCI-H1299-CDDP xenograft obtained at different time points after injection of 68Ga-NOTA-Nb109. The tumor was denoted with a dotted line circle. b Tissue uptake of 68Ga-NOTA-Nb109 in NCI-H1299-CDDP xenograft quantified by ROI analysis over the imaging time-course. c Tumor-to-muscle uptake ratio for 68Ga-NOTA-Nb109 in NCI-H1299-CDDP xenograft over time. All data were expressed as mean ± SD (n = 3). ***P < 0.001
